Struct QGraphicsProxyWidget

#[repr(C)]
pub struct QGraphicsProxyWidget { /* private fields */ }

The QGraphicsProxyWidget class provides a proxy layer for embedding a QWidget in a QGraphicsScene.

C++ class: QGraphicsProxyWidget.

C++ documentation:

The QGraphicsProxyWidget class provides a proxy layer for embedding a QWidget in a QGraphicsScene.

QGraphicsProxyWidget embeds QWidget-based widgets, for example, a QPushButton, QFontComboBox, or even QFileDialog, into QGraphicsScene. It forwards events between the two objects and translates between QWidget's integer-based geometry and QGraphicsWidget's qreal-based geometry. QGraphicsProxyWidget supports all core features of QWidget, including tab focus, keyboard input, Drag & Drop, and popups. You can also embed complex widgets, e.g., widgets with subwidgets.

Example:

int main(int argc, char argv)
{
      QApplication app(argc, argv);
      QTabWidget *tabWidget = new QTabWidget;
      QGraphicsScene scene;
      QGraphicsProxyWidget *proxy = scene.addWidget(tabWidget);
      QGraphicsView view(&scene);
      view.show();
      return app.exec();
}

QGraphicsProxyWidget takes care of automatically embedding popup children of embedded widgets through creating a child proxy for each popup. This means that when an embedded QComboBox shows its popup list, a new QGraphicsProxyWidget is created automatically, embedding the popup, and positioning it correctly. This only works if the popup is child of the embedded widget (for example QToolButton::setMenu() requires the QMenu instance to be child of the QToolButton).

Implementations

impl QGraphicsProxyWidget

pub fn slot_new_proxy_widget(&self) -> Receiver<(*const QWidget,)>

Creates a proxy widget for the given child of the widget contained in this proxy.

Returns a built-in Qt slot QGraphicsProxyWidget::newProxyWidget that can be passed to qt_core::Signal::connect.

C++ documentation:

Creates a proxy widget for the given child of the widget contained in this proxy.

You should not call this function directly; use QGraphicsProxyWidget::createProxyForChildWidget() instead.

This function is a fake virtual slot that you can reimplement in your subclass in order to control how new proxy widgets are created. The default implementation returns a proxy created with the QGraphicsProxyWidget() constructor with this proxy widget as the parent.

This function was introduced in Qt 4.5.

See also createProxyForChildWidget().

pub unsafe fn create_proxy_for_child_widget( &self, child: impl CastInto<Ptr<QWidget>>, ) -> QPtr<QGraphicsProxyWidget>

Creates a proxy widget for the given child of the widget contained in this proxy.

Calls C++ function: QGraphicsProxyWidget* QGraphicsProxyWidget::createProxyForChildWidget(QWidget* child).

C++ documentation:

Creates a proxy widget for the given child of the widget contained in this proxy.

This function makes it possible to acquire proxies for non top-level widgets. For instance, you can embed a dialog, and then transform only one of its widgets.

If the widget is already embedded, return the existing proxy widget.

This function was introduced in Qt 4.5.

See also newProxyWidget() and QGraphicsScene::addWidget().

pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>

Calls C++ function: virtual const QMetaObject* QGraphicsProxyWidget::metaObject() const.

pub unsafe fn new_2a( parent: impl CastInto<Ptr<QGraphicsItem>>, w_flags: QFlags<WindowType>, ) -> QBox<QGraphicsProxyWidget>

Constructs a new QGraphicsProxy widget. parent and wFlags are passed to QGraphicsItem's constructor.

Calls C++ function: [constructor] void QGraphicsProxyWidget::QGraphicsProxyWidget(QGraphicsItem* parent = …, QFlags<Qt::WindowType> wFlags = …).

C++ documentation:

Constructs a new QGraphicsProxy widget. parent and wFlags are passed to QGraphicsItem’s constructor.

pub unsafe fn new_0a() -> QBox<QGraphicsProxyWidget>

The QGraphicsProxyWidget class provides a proxy layer for embedding a QWidget in a QGraphicsScene.

Calls C++ function: [constructor] void QGraphicsProxyWidget::QGraphicsProxyWidget().

pub unsafe fn paint( &self, painter: impl CastInto<Ptr<QPainter>>, option: impl CastInto<Ptr<QStyleOptionGraphicsItem>>, widget: impl CastInto<Ptr<QWidget>>, )

Reimplemented from QGraphicsItem::paint().

Calls C++ function: virtual void QGraphicsProxyWidget::paint(QPainter* painter, const QStyleOptionGraphicsItem* option, QWidget* widget).

C++ documentation:

Reimplemented from QGraphicsItem::paint().

pub unsafe fn qt_metacall( &self, arg1: Call, arg2: c_int, arg3: *mut *mut c_void, ) -> c_int

Calls C++ function: virtual int QGraphicsProxyWidget::qt_metacall(QMetaObject::Call arg1, int arg2, void** arg3).

pub unsafe fn qt_metacast(&self, arg1: *const c_char) -> *mut c_void

Calls C++ function: virtual void* QGraphicsProxyWidget::qt_metacast(const char* arg1).

pub unsafe fn set_geometry(&self, rect: impl CastInto<Ref<QRectF>>)

Reimplemented from QGraphicsLayoutItem::setGeometry().

Calls C++ function: virtual void QGraphicsProxyWidget::setGeometry(const QRectF& rect).

C++ documentation:

Reimplemented from QGraphicsLayoutItem::setGeometry().

pub unsafe fn set_widget(&self, widget: impl CastInto<Ptr<QWidget>>)

Embeds widget into this proxy widget. The embedded widget must reside exclusively either inside or outside of Graphics View. You cannot embed a widget as long as it is is visible elsewhere in the UI, at the same time.

Calls C++ function: void QGraphicsProxyWidget::setWidget(QWidget* widget).

C++ documentation:

Embeds widget into this proxy widget. The embedded widget must reside exclusively either inside or outside of Graphics View. You cannot embed a widget as long as it is is visible elsewhere in the UI, at the same time.

widget must be a top-level widget whose parent is 0.

When the widget is embedded, its state (e.g., visible, enabled, geometry, size hints) is copied into the proxy widget. If the embedded widget is explicitly hidden or disabled, the proxy widget will become explicitly hidden or disabled after embedding is complete. The class documentation has a full overview over the shared state.

QGraphicsProxyWidget's window flags determine whether the widget, after embedding, will be given window decorations or not.

After this function returns, QGraphicsProxyWidget will keep its state synchronized with that of widget whenever possible.

If a widget is already embedded by this proxy when this function is called, that widget will first be automatically unembedded. Passing 0 for the widget argument will only unembed the widget, and the ownership of the currently embedded widget will be passed on to the caller. Every child widget that are embedded will also be embedded and their proxy widget destroyed.

Note that widgets with the Qt::WA_PaintOnScreen widget attribute set and widgets that wrap an external application or controller cannot be embedded. Examples are QGLWidget and QAxWidget.

See also widget().

pub unsafe fn static_meta_object() -> Ref<QMetaObject>

Returns a reference to the staticMetaObject field.

pub unsafe fn sub_widget_rect( &self, widget: impl CastInto<Ptr<QWidget>>, ) -> CppBox<QRectF>

Returns the rectangle for widget, which must be a descendant of widget(), or widget() itself, in this proxy item's local coordinates.

Calls C++ function: QRectF QGraphicsProxyWidget::subWidgetRect(const QWidget* widget) const.

C++ documentation:

Returns the rectangle for widget, which must be a descendant of widget(), or widget() itself, in this proxy item’s local coordinates.

If no widget is embedded, widget is 0, or widget is not a descendant of the embedded widget, this function returns an empty QRectF.

See also widget().

pub unsafe fn tr( s: *const c_char, c: *const c_char, n: c_int, ) -> CppBox<QString>

Calls C++ function: static QString QGraphicsProxyWidget::tr(const char* s, const char* c, int n).

pub unsafe fn tr_utf8( s: *const c_char, c: *const c_char, n: c_int, ) -> CppBox<QString>

Calls C++ function: static QString QGraphicsProxyWidget::trUtf8(const char* s, const char* c, int n).

pub unsafe fn type_(&self) -> c_int

Reimplemented from QGraphicsItem::type().

See also setWidget().

Methods from Deref<Target = QGraphicsWidget>

pub fn geometry_changed(&self) -> Signal<()>

This signal gets emitted whenever the geometry is changed in setGeometry().

Returns a built-in Qt signal QGraphicsWidget::geometryChanged that can be passed to qt_core::Signal::connect.

C++ documentation:

This signal gets emitted whenever the geometry is changed in setGeometry().

Note: Notifier signal for property geometry. Notifier signal for property size.

pub fn layout_changed(&self) -> Signal<()>

This property holds the layout of the widget

Returns a built-in Qt signal QGraphicsWidget::layoutChanged that can be passed to qt_core::Signal::connect.

C++ documentation:

This property holds the layout of the widget

Any existing layout manager is deleted before the new layout is assigned. If layout is nullptr, the widget is left without a layout. Existing subwidgets' geometries will remain unaffected.

QGraphicsWidget takes ownership of layout.

All widgets that are currently managed by layout or all of its sublayouts, are automatically reparented to this item. The layout is then invalidated, and the child widget geometries are adjusted according to this item's geometry() and contentsMargins(). Children who are not explicitly managed by layout remain unaffected by the layout after it has been assigned to this widget.

If no layout is currently managing this widget, layout() will return nullptr.

Access functions:

QGraphicsLayout *	layout() const
void	setLayout(QGraphicsLayout *layout)

Notifier signal:

void	layoutChanged()

pub fn slot_close(&self) -> Receiver<()>

Call this function to close the widget.

Returns a built-in Qt slot QGraphicsWidget::close that can be passed to qt_core::Signal::connect.

C++ documentation:

Call this function to close the widget.

Returns true if the widget was closed; otherwise returns false. This slot will first send a QCloseEvent to the widget, which may or may not accept the event. If the event was ignored, nothing happens. If the event was accepted, it will hide() the widget.

If the widget has the Qt::WA_DeleteOnClose attribute set it will be deleted.

pub unsafe fn actions(&self) -> CppBox<QListOfQAction>

Returns the (possibly empty) list of this widget's actions.

Calls C++ function: QList<QAction*> QGraphicsWidget::actions() const.

C++ documentation:

Returns the (possibly empty) list of this widget’s actions.

This function was introduced in Qt 4.5.

See also insertAction(), removeAction(), QWidget::actions(), QAction::associatedWidgets(), and QAction::associatedGraphicsWidgets().

pub unsafe fn add_action(&self, action: impl CastInto<Ptr<QAction>>)

Appends the action action to this widget's list of actions.

Calls C++ function: void QGraphicsWidget::addAction(QAction* action).

C++ documentation:

Appends the action action to this widget’s list of actions.

All QGraphicsWidgets have a list of QActions, however they can be represented graphically in many different ways. The default use of the QAction list (as returned by actions()) is to create a context QMenu.

A QGraphicsWidget should only have one of each action and adding an action it already has will not cause the same action to be in the widget twice.

This function was introduced in Qt 4.5.

See also removeAction(), insertAction(), actions(), and QWidget::addAction().

pub unsafe fn add_actions(&self, actions: impl CastInto<Ref<QListOfQAction>>)

Appends the actions actions to this widget's list of actions.

Calls C++ function: void QGraphicsWidget::addActions(QList<QAction*> actions).

C++ documentation:

Appends the actions actions to this widget’s list of actions.

This function was introduced in Qt 4.5.

See also removeAction(), QMenu, addAction(), and QWidget::addActions().

pub unsafe fn adjust_size(&self)

Adjusts the size of the widget to its effective preferred size hint.

Calls C++ function: void QGraphicsWidget::adjustSize().

C++ documentation:

Adjusts the size of the widget to its effective preferred size hint.

This function is called implicitly when the item is shown for the first time.

See also effectiveSizeHint() and Qt::MinimumSize.

pub unsafe fn auto_fill_background(&self) -> bool

This property holds whether the widget background is filled automatically

Calls C++ function: bool QGraphicsWidget::autoFillBackground() const.

C++ documentation:

This property holds whether the widget background is filled automatically

If enabled, this property will cause Qt to fill the background of the widget before invoking the paint() method. The color used is defined by the QPalette::Window color role from the widget's palette.

In addition, Windows are always filled with QPalette::Window, unless the WA_OpaquePaintEvent or WA_NoSystemBackground attributes are set.

By default, this property is false.

This property was introduced in Qt 4.7.

Access functions:

bool	autoFillBackground() const
void	setAutoFillBackground(bool enabled)

See also Qt::WA_OpaquePaintEvent and Qt::WA_NoSystemBackground.

pub unsafe fn bounding_rect(&self) -> CppBox<QRectF>

Reimplemented from QGraphicsItem::boundingRect().

Calls C++ function: virtual QRectF QGraphicsWidget::boundingRect() const.

C++ documentation:

Reimplemented from QGraphicsItem::boundingRect().

pub unsafe fn close(&self) -> bool

Call this function to close the widget.

Calls C++ function: [slot] bool QGraphicsWidget::close().

C++ documentation:

Call this function to close the widget.

Returns true if the widget was closed; otherwise returns false. This slot will first send a QCloseEvent to the widget, which may or may not accept the event. If the event was ignored, nothing happens. If the event was accepted, it will hide() the widget.

If the widget has the Qt::WA_DeleteOnClose attribute set it will be deleted.

pub unsafe fn focus_policy(&self) -> FocusPolicy

This property holds the way the widget accepts keyboard focus

Calls C++ function: Qt::FocusPolicy QGraphicsWidget::focusPolicy() const.

C++ documentation:

This property holds the way the widget accepts keyboard focus

The focus policy is Qt::TabFocus if the widget accepts keyboard focus by tabbing, Qt::ClickFocus if the widget accepts focus by clicking, Qt::StrongFocus if it accepts both, and Qt::NoFocus (the default) if it does not accept focus at all.

You must enable keyboard focus for a widget if it processes keyboard events. This is normally done from the widget's constructor. For instance, the QLineEdit constructor calls setFocusPolicy(Qt::StrongFocus).

If you enable a focus policy (i.e., not Qt::NoFocus), QGraphicsWidget will automatically enable the ItemIsFocusable flag. Setting Qt::NoFocus on a widget will clear the ItemIsFocusable flag. If the widget currently has keyboard focus, the widget will automatically lose focus.

Access functions:

Qt::FocusPolicy	focusPolicy() const
void	setFocusPolicy(Qt::FocusPolicy policy)

See also focusInEvent(), focusOutEvent(), keyPressEvent(), keyReleaseEvent(), and enabled.

pub unsafe fn focus_widget(&self) -> QPtr<QGraphicsWidget>

If this widget, a child or descendant of this widget currently has input focus, this function will return a pointer to that widget. If no descendant widget has input focus, 0 is returned.

Calls C++ function: QGraphicsWidget* QGraphicsWidget::focusWidget() const.

C++ documentation:

If this widget, a child or descendant of this widget currently has input focus, this function will return a pointer to that widget. If no descendant widget has input focus, 0 is returned.

See also QGraphicsItem::focusItem() and QWidget::focusWidget().

pub unsafe fn font(&self) -> CppBox<QFont>

This property holds the widgets' font

Calls C++ function: QFont QGraphicsWidget::font() const.

C++ documentation:

This property holds the widgets’ font

This property provides the widget's font.

QFont consists of font properties that have been explicitly defined and properties implicitly inherited from the widget's parent. Hence, font() can return a different font compared to the one set with setFont(). This scheme allows you to define single entries in a font without affecting the font's inherited entries.

When a widget's font changes, it resolves its entries against its parent widget. If the widget does not have a parent widget, it resolves its entries against the scene. The widget then sends itself a FontChange event and notifies all its descendants so that they can resolve their fonts as well.

By default, this property contains the application's default font.

Access functions:

QFont	font() const
void	setFont(const QFont &font)

See also QApplication::font(), QGraphicsScene::font, and QFont::resolve().

pub unsafe fn get_contents_margins( &self, left: *mut c_double, top: *mut c_double, right: *mut c_double, bottom: *mut c_double, )

Reimplemented from QGraphicsLayoutItem::getContentsMargins().

Calls C++ function: virtual void QGraphicsWidget::getContentsMargins(double* left, double* top, double* right, double* bottom) const.

C++ documentation:

Reimplemented from QGraphicsLayoutItem::getContentsMargins().

Gets the widget's contents margins. The margins are stored in left, top, right and bottom, as pointers to qreals. Each argument can be omitted by passing 0.

See also setContentsMargins().

pub unsafe fn get_window_frame_margins( &self, left: *mut c_double, top: *mut c_double, right: *mut c_double, bottom: *mut c_double, )

Gets the widget's window frame margins. The margins are stored in left, top, right and bottom as pointers to qreals. Each argument can be omitted by passing 0.

Calls C++ function: void QGraphicsWidget::getWindowFrameMargins(double* left, double* top, double* right, double* bottom) const.

C++ documentation:

Gets the widget’s window frame margins. The margins are stored in left, top, right and bottom as pointers to qreals. Each argument can be omitted by passing 0.

See also setWindowFrameMargins() and windowFrameRect().

pub unsafe fn grab_shortcut_2a( &self, sequence: impl CastInto<Ref<QKeySequence>>, context: ShortcutContext, ) -> c_int

Adds a shortcut to Qt's shortcut system that watches for the given key sequence in the given context. If the context is Qt::ApplicationShortcut, the shortcut applies to the application as a whole. Otherwise, it is either local to this widget, Qt::WidgetShortcut, or to the window itself, Qt::WindowShortcut. For widgets that are not part of a window (i.e., top-level widgets and their children), Qt::WindowShortcut shortcuts apply to the scene.

Calls C++ function: int QGraphicsWidget::grabShortcut(const QKeySequence& sequence, Qt::ShortcutContext context = …).

C++ documentation:

Adds a shortcut to Qt’s shortcut system that watches for the given key sequence in the given context. If the context is Qt::ApplicationShortcut, the shortcut applies to the application as a whole. Otherwise, it is either local to this widget, Qt::WidgetShortcut, or to the window itself, Qt::WindowShortcut. For widgets that are not part of a window (i.e., top-level widgets and their children), Qt::WindowShortcut shortcuts apply to the scene.

If the same key sequence has been grabbed by several widgets, when the key sequence occurs a QEvent::Shortcut event is sent to all the widgets to which it applies in a non-deterministic order, but with the ``ambiguous'' flag set to true.

Warning: You should not normally need to use this function; instead create QActions with the shortcut key sequences you require (if you also want equivalent menu options and toolbar buttons), or create QShortcuts if you just need key sequences. Both QAction and QShortcut handle all the event filtering for you, and provide signals which are triggered when the user triggers the key sequence, so are much easier to use than this low-level function.

This function was introduced in Qt 4.5.

See also releaseShortcut(), setShortcutEnabled(), and QWidget::grabShortcut().

pub unsafe fn grab_shortcut_1a( &self, sequence: impl CastInto<Ref<QKeySequence>>, ) -> c_int

Adds a shortcut to Qt's shortcut system that watches for the given key sequence in the given context. If the context is Qt::ApplicationShortcut, the shortcut applies to the application as a whole. Otherwise, it is either local to this widget, Qt::WidgetShortcut, or to the window itself, Qt::WindowShortcut. For widgets that are not part of a window (i.e., top-level widgets and their children), Qt::WindowShortcut shortcuts apply to the scene.

Calls C++ function: int QGraphicsWidget::grabShortcut(const QKeySequence& sequence).

pub unsafe fn insert_action( &self, before: impl CastInto<Ptr<QAction>>, action: impl CastInto<Ptr<QAction>>, )

Inserts the action action to this widget's list of actions, before the action before. It appends the action if before is 0 or before is not a valid action for this widget.

Calls C++ function: void QGraphicsWidget::insertAction(QAction* before, QAction* action).

C++ documentation:

Inserts the action action to this widget’s list of actions, before the action before. It appends the action if before is 0 or before is not a valid action for this widget.

A QGraphicsWidget should only have one of each action.

This function was introduced in Qt 4.5.

See also removeAction(), addAction(), QMenu, actions(), and QWidget::insertActions().

pub unsafe fn insert_actions( &self, before: impl CastInto<Ptr<QAction>>, actions: impl CastInto<Ref<QListOfQAction>>, )

This function was introduced in Qt 4.5.

See also removeAction(), QMenu, insertAction(), and QWidget::insertActions().

pub unsafe fn is_active_window(&self) -> bool

Returns true if this widget's window is in the active window, or if the widget does not have a window but is in an active scene (i.e., a scene that currently has focus).

Calls C++ function: bool QGraphicsWidget::isActiveWindow() const.

C++ documentation:

Returns true if this widget’s window is in the active window, or if the widget does not have a window but is in an active scene (i.e., a scene that currently has focus).

The active window is the window that either contains a child widget that currently has input focus, or that itself has input focus.

See also QGraphicsScene::activeWindow(), QGraphicsScene::setActiveWindow(), and isActive().

pub unsafe fn layout(&self) -> Ptr<QGraphicsLayout>

This property holds the layout of the widget

Calls C++ function: QGraphicsLayout* QGraphicsWidget::layout() const.

C++ documentation:

This property holds the layout of the widget

Any existing layout manager is deleted before the new layout is assigned. If layout is 0, the widget is left without a layout. Existing subwidgets' geometries will remain unaffected.

QGraphicsWidget takes ownership of layout.

All widgets that are currently managed by layout or all of its sublayouts, are automatically reparented to this item. The layout is then invalidated, and the child widget geometries are adjusted according to this item's geometry() and contentsMargins(). Children who are not explicitly managed by layout remain unaffected by the layout after it has been assigned to this widget.

If no layout is currently managing this widget, layout() will return 0.

Access functions:

QGraphicsLayout *	layout() const
void	setLayout(QGraphicsLayout *layout)

pub unsafe fn layout_direction(&self) -> LayoutDirection

This property holds the layout direction for this widget.

Calls C++ function: Qt::LayoutDirection QGraphicsWidget::layoutDirection() const.

C++ documentation:

This property holds the layout direction for this widget.

This property modifies this widget's and all of its descendants' Qt::WA_RightToLeft attribute. It also sets this widget's Qt::WA_SetLayoutDirection attribute.

The widget's layout direction determines the order in which the layout manager horizontally arranges subwidgets of this widget. The default value depends on the language and locale of the application, and is typically in the same direction as words are read and written. With Qt::LeftToRight, the layout starts placing subwidgets from the left side of this widget towards the right. Qt::RightToLeft does the opposite - the layout will place widgets starting from the right edge moving towards the left.

Subwidgets inherit their layout direction from the parent. Top-level widget items inherit their layout direction from QGraphicsScene::layoutDirection. If you change a widget's layout direction by calling setLayoutDirection(), the widget will send itself a LayoutDirectionChange event, and then propagate the new layout direction to all its descendants.

Access functions:

Qt::LayoutDirection	layoutDirection() const
void	setLayoutDirection(Qt::LayoutDirection direction)
void	unsetLayoutDirection()

See also QWidget::layoutDirection and QApplication::layoutDirection.

pub unsafe fn palette(&self) -> CppBox<QPalette>

This property holds the widget's palette

Calls C++ function: QPalette QGraphicsWidget::palette() const.

C++ documentation:

This property holds the widget’s palette

This property provides the widget's palette. The palette provides colors and brushes for color groups (e.g., QPalette::Button) and states (e.g., QPalette::Inactive), loosely defining the general look of the widget and its children.

QPalette consists of color groups that have been explicitly defined, and groups that are implicitly inherited from the widget's parent. Because of this, palette() can return a different palette than what has been set with setPalette(). This scheme allows you to define single entries in a palette without affecting the palette's inherited entries.

When a widget's palette changes, it resolves its entries against its parent widget, or if it doesn't have a parent widget, it resolves against the scene. It then sends itself a PaletteChange event, and notifies all its descendants so they can resolve their palettes as well.

By default, this property contains the application's default palette.

Access functions:

QPalette	palette() const

See also setGeometry() and resize().

pub unsafe fn release_shortcut(&self, id: c_int)

Removes the shortcut with the given id from Qt's shortcut system. The widget will no longer receive QEvent::Shortcut events for the shortcut's key sequence (unless it has other shortcuts with the same key sequence).

Calls C++ function: void QGraphicsWidget::releaseShortcut(int id).

C++ documentation:

Removes the shortcut with the given id from Qt’s shortcut system. The widget will no longer receive QEvent::Shortcut events for the shortcut’s key sequence (unless it has other shortcuts with the same key sequence).

Warning: You should not normally need to use this function since Qt's shortcut system removes shortcuts automatically when their parent widget is destroyed. It is best to use QAction or QShortcut to handle shortcuts, since they are easier to use than this low-level function. Note also that this is an expensive operation.

This function was introduced in Qt 4.5.

See also grabShortcut(), setShortcutEnabled(), and QWidget::releaseShortcut().

pub unsafe fn remove_action(&self, action: impl CastInto<Ptr<QAction>>)

Removes the action action from this widget's list of actions.

Calls C++ function: void QGraphicsWidget::removeAction(QAction* action).

pub unsafe fn resize_1a(&self, size: impl CastInto<Ref<QSizeF>>)

This property holds the size of the widget

Calls C++ function: void QGraphicsWidget::resize(const QSizeF& size).

C++ documentation:

This property holds the size of the widget

Calling resize() resizes the widget to a size bounded by minimumSize() and maximumSize(). This property only affects the widget's width and height (e.g., its right and bottom edges); the widget's position and top-left corner remains unaffected.

Resizing a widget triggers the widget to immediately receive a GraphicsSceneResize event with the widget's old and new size. If the widget has a layout assigned when this event arrives, the layout will be activated and it will automatically update any child widgets's geometry.

This property does not affect any layout of the parent widget. If the widget itself is managed by a parent layout; e.g., it has a parent widget with a layout assigned, that layout will not activate.

By default, this property contains a size with zero width and height.

Access functions:

QSizeF	size() const
void	resize(const QSizeF &size)
void	resize(qreal w, qreal h)

Notifier signal:

void	geometryChanged()

See also setGeometry(), QGraphicsSceneResizeEvent, and QGraphicsLayout.

pub unsafe fn resize_2a(&self, w: c_double, h: c_double)

pub unsafe fn set_attribute_2a(&self, attribute: WidgetAttribute, on: bool)

If on is true, this function enables attribute; otherwise attribute is disabled.

Calls C++ function: void QGraphicsWidget::setAttribute(Qt::WidgetAttribute attribute, bool on = …).

C++ documentation:

If on is true, this function enables attribute; otherwise attribute is disabled.

See the class documentation for QGraphicsWidget for a complete list of which attributes are supported, and what they are for.

See also testAttribute() and QWidget::setAttribute().

pub unsafe fn set_attribute_1a(&self, attribute: WidgetAttribute)

If on is true, this function enables attribute; otherwise attribute is disabled.

Calls C++ function: void QGraphicsWidget::setAttribute(Qt::WidgetAttribute attribute).

C++ documentation:

pub unsafe fn set_auto_fill_background(&self, enabled: bool)

This property holds whether the widget background is filled automatically

Calls C++ function: void QGraphicsWidget::setAutoFillBackground(bool enabled).

C++ documentation:

This property holds whether the widget background is filled automatically

If enabled, this property will cause Qt to fill the background of the widget before invoking the paint() method. The color used is defined by the QPalette::Window color role from the widget's palette.

In addition, Windows are always filled with QPalette::Window, unless the WA_OpaquePaintEvent or WA_NoSystemBackground attributes are set.

By default, this property is false.

This property was introduced in Qt 4.7.

Access functions:

bool	autoFillBackground() const
void	setAutoFillBackground(bool enabled)

See also Qt::WA_OpaquePaintEvent and Qt::WA_NoSystemBackground.

pub unsafe fn set_contents_margins_4a( &self, left: c_double, top: c_double, right: c_double, bottom: c_double, )

Sets the widget's contents margins to left, top, right and bottom.

Calls C++ function: void QGraphicsWidget::setContentsMargins(double left, double top, double right, double bottom).

C++ documentation:

Sets the widget’s contents margins to left, top, right and bottom.

Contents margins are used by the assigned layout to define the placement of subwidgets and layouts. Margins are particularly useful for widgets that constrain subwidgets to only a section of its own geometry. For example, a group box with a layout will place subwidgets inside its frame, but below the title.

Changing a widget's contents margins will always trigger an update(), and any assigned layout will be activated automatically. The widget will then receive a ContentsRectChange event.

See also getContentsMargins() and setGeometry().

pub unsafe fn set_contents_margins_1a( &self, margins: impl CastInto<Ref<QMarginsF>>, )

Available on cpp_lib_version="5.14.0" only.

Sets the widget's contents margins to margins.

Calls C++ function: void QGraphicsWidget::setContentsMargins(QMarginsF margins).

C++ documentation:

Sets the widget’s contents margins to margins.

Contents margins are used by the assigned layout to define the placement of subwidgets and layouts. Margins are particularly useful for widgets that constrain subwidgets to only a section of its own geometry. For example, a group box with a layout will place subwidgets inside its frame, but below the title.

Changing a widget's contents margins will always trigger an update(), and any assigned layout will be activated automatically. The widget will then receive a ContentsRectChange event.

This function was introduced in Qt 5.14.

See also getContentsMargins() and setGeometry().

pub unsafe fn set_focus_policy(&self, policy: FocusPolicy)

This property holds the way the widget accepts keyboard focus

Calls C++ function: void QGraphicsWidget::setFocusPolicy(Qt::FocusPolicy policy).

C++ documentation:

This property holds the way the widget accepts keyboard focus

The focus policy is Qt::TabFocus if the widget accepts keyboard focus by tabbing, Qt::ClickFocus if the widget accepts focus by clicking, Qt::StrongFocus if it accepts both, and Qt::NoFocus (the default) if it does not accept focus at all.

You must enable keyboard focus for a widget if it processes keyboard events. This is normally done from the widget's constructor. For instance, the QLineEdit constructor calls setFocusPolicy(Qt::StrongFocus).

If you enable a focus policy (i.e., not Qt::NoFocus), QGraphicsWidget will automatically enable the ItemIsFocusable flag. Setting Qt::NoFocus on a widget will clear the ItemIsFocusable flag. If the widget currently has keyboard focus, the widget will automatically lose focus.

Access functions:

Qt::FocusPolicy	focusPolicy() const
void	setFocusPolicy(Qt::FocusPolicy policy)

See also focusInEvent(), focusOutEvent(), keyPressEvent(), keyReleaseEvent(), and enabled.

pub unsafe fn set_font(&self, font: impl CastInto<Ref<QFont>>)

This property holds the widgets' font

Calls C++ function: void QGraphicsWidget::setFont(const QFont& font).

C++ documentation:

This property holds the widgets’ font

This property provides the widget's font.

QFont consists of font properties that have been explicitly defined and properties implicitly inherited from the widget's parent. Hence, font() can return a different font compared to the one set with setFont(). This scheme allows you to define single entries in a font without affecting the font's inherited entries.

When a widget's font changes, it resolves its entries against its parent widget. If the widget does not have a parent widget, it resolves its entries against the scene. The widget then sends itself a FontChange event and notifies all its descendants so that they can resolve their fonts as well.

By default, this property contains the application's default font.

Access functions:

QFont	font() const
void	setFont(const QFont &font)

See also QApplication::font(), QGraphicsScene::font, and QFont::resolve().

pub unsafe fn set_geometry_1a(&self, rect: impl CastInto<Ref<QRectF>>)

This property holds the geometry of the widget

Calls C++ function: virtual void QGraphicsWidget::setGeometry(const QRectF& rect).

C++ documentation:

This property holds the geometry of the widget

Sets the item's geometry to rect. The item's position and size are modified as a result of calling this function. The item is first moved, then resized.

A side effect of calling this function is that the widget will receive a move event and a resize event. Also, if the widget has a layout assigned, the layout will activate.

Access functions:

virtual void	setGeometry(const QRectF &rect)
void	setGeometry(qreal x, qreal y, qreal w, qreal h)

Notifier signal:

void	geometryChanged()

See also geometry() and resize().

pub unsafe fn set_geometry_4a( &self, x: c_double, y: c_double, w: c_double, h: c_double, )

This property holds the geometry of the widget

Calls C++ function: void QGraphicsWidget::setGeometry(double x, double y, double w, double h).

C++ documentation:

This property holds the geometry of the widget

Sets the item's geometry to rect. The item's position and size are modified as a result of calling this function. The item is first moved, then resized.

A side effect of calling this function is that the widget will receive a move event and a resize event. Also, if the widget has a layout assigned, the layout will activate.

Access functions:

virtual void	setGeometry(const QRectF &rect)
void	setGeometry(qreal x, qreal y, qreal w, qreal h)

Notifier signal:

void	geometryChanged()

See also geometry() and resize().

pub unsafe fn set_layout(&self, layout: impl CastInto<Ptr<QGraphicsLayout>>)

Sets the layout for this widget to layout. Any existing layout manager is deleted before the new layout is assigned. If layout is 0, the widget is left without a layout. Existing subwidgets' geometries will remain unaffected.

Calls C++ function: void QGraphicsWidget::setLayout(QGraphicsLayout* layout).

C++ documentation:

Sets the layout for this widget to layout. Any existing layout manager is deleted before the new layout is assigned. If layout is 0, the widget is left without a layout. Existing subwidgets’ geometries will remain unaffected.

All widgets that are currently managed by layout or all of its sublayouts, are automatically reparented to this item. The layout is then invalidated, and the child widget geometries are adjusted according to this item's geometry() and contentsMargins(). Children who are not explicitly managed by layout remain unaffected by the layout after it has been assigned to this widget.

QGraphicsWidget takes ownership of layout.

Note: Setter function for property layout.

See also layout(), QGraphicsLinearLayout::addItem(), and QGraphicsLayout::invalidate().

pub unsafe fn set_layout_direction(&self, direction: LayoutDirection)

This property holds the layout direction for this widget.

Calls C++ function: void QGraphicsWidget::setLayoutDirection(Qt::LayoutDirection direction).

C++ documentation:

This property holds the layout direction for this widget.

This property modifies this widget's and all of its descendants' Qt::WA_RightToLeft attribute. It also sets this widget's Qt::WA_SetLayoutDirection attribute.

The widget's layout direction determines the order in which the layout manager horizontally arranges subwidgets of this widget. The default value depends on the language and locale of the application, and is typically in the same direction as words are read and written. With Qt::LeftToRight, the layout starts placing subwidgets from the left side of this widget towards the right. Qt::RightToLeft does the opposite - the layout will place widgets starting from the right edge moving towards the left.

Subwidgets inherit their layout direction from the parent. Top-level widget items inherit their layout direction from QGraphicsScene::layoutDirection. If you change a widget's layout direction by calling setLayoutDirection(), the widget will send itself a LayoutDirectionChange event, and then propagate the new layout direction to all its descendants.

Access functions:

Qt::LayoutDirection	layoutDirection() const
void	setLayoutDirection(Qt::LayoutDirection direction)
void	unsetLayoutDirection()

See also QWidget::layoutDirection and QApplication::layoutDirection.

pub unsafe fn set_palette(&self, palette: impl CastInto<Ref<QPalette>>)

This property holds the widget's palette

Calls C++ function: void QGraphicsWidget::setPalette(const QPalette& palette).

C++ documentation:

This property holds the widget’s palette

This property provides the widget's palette. The palette provides colors and brushes for color groups (e.g., QPalette::Button) and states (e.g., QPalette::Inactive), loosely defining the general look of the widget and its children.

QPalette consists of color groups that have been explicitly defined, and groups that are implicitly inherited from the widget's parent. Because of this, palette() can return a different palette than what has been set with setPalette(). This scheme allows you to define single entries in a palette without affecting the palette's inherited entries.

When a widget's palette changes, it resolves its entries against its parent widget, or if it doesn't have a parent widget, it resolves against the scene. It then sends itself a PaletteChange event, and notifies all its descendants so they can resolve their palettes as well.

By default, this property contains the application's default palette.

Access functions:

QPalette	palette() const
void	setPalette(const QPalette &palette)

See also QApplication::palette(), QGraphicsScene::palette, and QPalette::resolve().

pub unsafe fn set_shortcut_enabled_2a(&self, id: c_int, enabled: bool)

If enabled is true, the shortcut with the given id is enabled; otherwise the shortcut is disabled.

Calls C++ function: void QGraphicsWidget::setShortcutEnabled(int id, bool enabled = …).

C++ documentation:

If enabled is true, the shortcut with the given id is enabled; otherwise the shortcut is disabled.

Warning: You should not normally need to use this function since Qt's shortcut system enables/disables shortcuts automatically as widgets become hidden/visible and gain or lose focus. It is best to use QAction or QShortcut to handle shortcuts, since they are easier to use than this low-level function.

This function was introduced in Qt 4.5.

See also grabShortcut(), releaseShortcut(), and QWidget::setShortcutEnabled().

pub unsafe fn set_style(&self, style: impl CastInto<Ptr<QStyle>>)

Sets the widget's style to style. QGraphicsWidget does not take ownership of style.

Calls C++ function: void QGraphicsWidget::setStyle(QStyle* style).

C++ documentation:

Sets the widget’s style to style. QGraphicsWidget does not take ownership of style.

If no style is assigned, or style is 0, the widget will use QGraphicsScene::style() (if this has been set). Otherwise the widget will use QApplication::style().

This function sets the Qt::WA_SetStyle attribute if style is not 0; otherwise it clears the attribute.

See also style().

pub unsafe fn set_window_flags(&self, w_flags: QFlags<WindowType>)

This property holds the widget's window flags

Calls C++ function: void QGraphicsWidget::setWindowFlags(QFlags<Qt::WindowType> wFlags).

C++ documentation:

This property holds the widget’s window flags

Window flags are a combination of a window type (e.g., Qt::Dialog) and several flags giving hints on the behavior of the window. The behavior is platform-dependent.

By default, this property contains no window flags.

Methods from Deref<Target = QObject>

pub unsafe fn find_child<T>( &self, name: &str, ) -> Result<QPtr<T>, FindChildError>

where QObject: DynamicCast<T>, T: StaticUpcast<QObject>,

Finds a child of self with the specified object name and casts it to type T.

The search is performed recursively. If there is more than one child matching the search, the most direct ancestor is returned. If there are several direct ancestors, it is undefined which one will be returned.

Returns an error if there is no child object with object name name or the found object cannot be cast to T.

pub fn destroyed(&self) -> Signal<(*mut QObject,)>

This signal is emitted immediately before the object obj is destroyed, and can not be blocked.

Returns a built-in Qt signal QObject::destroyed that can be passed to qt_core::Signal::connect.

C++ documentation:

See also deleteLater() and QPointer.

pub fn object_name_changed(&self) -> Signal<(*const QString,)>

This signal is emitted after the object's name has been changed. The new object name is passed as objectName.

Returns a built-in Qt signal QObject::objectNameChanged that can be passed to qt_core::Signal::connect.

C++ documentation:

This signal is emitted after the object’s name has been changed. The new object name is passed as objectName.

Note: This is a private signal. It can be used in signal connections but cannot be emitted by the user.

Note: Notifier signal for property objectName.

See also QObject::objectName.

pub fn slot_delete_later(&self) -> Receiver<()>

Schedules this object for deletion.

Returns a built-in Qt slot QObject::deleteLater that can be passed to qt_core::Signal::connect.

C++ documentation:

Schedules this object for deletion.

The object will be deleted when control returns to the event loop. If the event loop is not running when this function is called (e.g. deleteLater() is called on an object before QCoreApplication::exec()), the object will be deleted once the event loop is started. If deleteLater() is called after the main event loop has stopped, the object will not be deleted. Since Qt 4.8, if deleteLater() is called on an object that lives in a thread with no running event loop, the object will be destroyed when the thread finishes.

Note that entering and leaving a new event loop (e.g., by opening a modal dialog) will not perform the deferred deletion; for the object to be deleted, the control must return to the event loop from which deleteLater() was called.

Note: It is safe to call this function more than once; when the first deferred deletion event is delivered, any pending events for the object are removed from the event queue.

See also destroyed() and QPointer.

pub unsafe fn block_signals(&self, b: bool) -> bool

If block is true, signals emitted by this object are blocked (i.e., emitting a signal will not invoke anything connected to it). If block is false, no such blocking will occur.

Calls C++ function: bool QObject::blockSignals(bool b).

C++ documentation:

If block is true, signals emitted by this object are blocked (i.e., emitting a signal will not invoke anything connected to it). If block is false, no such blocking will occur.

The return value is the previous value of signalsBlocked().

Note that the destroyed() signal will be emitted even if the signals for this object have been blocked.

Signals emitted while being blocked are not buffered.

See also signalsBlocked() and QSignalBlocker.

pub unsafe fn children(&self) -> Ref<QListOfQObject>

Returns a list of child objects. The QObjectList class is defined in the <QObject> header file as the following:

Calls C++ function: const QList<QObject*>& QObject::children() const.

C++ documentation:

Returns a list of child objects. The QObjectList class is defined in the <QObject> header file as the following:

  typedef QList<QObject*> QObjectList;

The first child added is the first object in the list and the last child added is the last object in the list, i.e. new children are appended at the end.

Note that the list order changes when QWidget children are raised or lowered. A widget that is raised becomes the last object in the list, and a widget that is lowered becomes the first object in the list.

See also findChild(), findChildren(), parent(), and setParent().

pub unsafe fn delete_later(&self)

Schedules this object for deletion.

Calls C++ function: [slot] void QObject::deleteLater().

C++ documentation:

Schedules this object for deletion.

The object will be deleted when control returns to the event loop. If the event loop is not running when this function is called (e.g. deleteLater() is called on an object before QCoreApplication::exec()), the object will be deleted once the event loop is started. If deleteLater() is called after the main event loop has stopped, the object will not be deleted. Since Qt 4.8, if deleteLater() is called on an object that lives in a thread with no running event loop, the object will be destroyed when the thread finishes.

Note that entering and leaving a new event loop (e.g., by opening a modal dialog) will not perform the deferred deletion; for the object to be deleted, the control must return to the event loop from which deleteLater() was called.

Note: It is safe to call this function more than once; when the first deferred deletion event is delivered, any pending events for the object are removed from the event queue.

Returns true if c1 and c2 are the same Unicode character; otherwise returns false.

pub unsafe fn event(&self, event: impl CastInto<Ptr<QEvent>>) -> bool

This virtual function receives events to an object and should return true if the event e was recognized and processed.

Calls C++ function: virtual bool QObject::event(QEvent* event).

C++ documentation:

This virtual function receives events to an object and should return true if the event e was recognized and processed.

The event() function can be reimplemented to customize the behavior of an object.

Make sure you call the parent event class implementation for all the events you did not handle.

Example:

class MyClass : public QWidget
{
      Q_OBJECT
public:
      MyClass(QWidget *parent = 0);
      ~MyClass();
      bool event(QEvent* ev)
      {

          } else  if (ev->type() == QEvent::Show) {
              // complement handling of Show if any
              doThings2();
              QWidget::event(ev);
              return true;
          }
          // Make sure the rest of events are handled
          return QWidget::event(ev);
      }
};

See also installEventFilter(), timerEvent(), QCoreApplication::sendEvent(), and QCoreApplication::postEvent().

pub unsafe fn event_filter( &self, watched: impl CastInto<Ptr<QObject>>, event: impl CastInto<Ptr<QEvent>>, ) -> bool

Filters events if this object has been installed as an event filter for the watched object.

Calls C++ function: virtual bool QObject::eventFilter(QObject* watched, QEvent* event).

C++ documentation:

Filters events if this object has been installed as an event filter for the watched object.

In your reimplementation of this function, if you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Example:

class MainWindow : public QMainWindow
{
public:
      MainWindow();
protected:
      bool eventFilter(QObject obj, QEvent ev);
private:
      QTextEdit *textEdit;
};
MainWindow::MainWindow()
{
      textEdit = new QTextEdit;
      setCentralWidget(textEdit);
      textEdit->installEventFilter(this);
}
bool MainWindow::eventFilter(QObject obj, QEvent event)
{
      if (obj == textEdit) {
          if (event->type() == QEvent::KeyPress) {
              QKeyEvent keyEvent = static_cast<QKeyEvent>(event);
              qDebug() << “Ate key press” << keyEvent->key();
              return true;
          } else {
              return false;
          }
      } else {
          // pass the event on to the parent class
          return QMainWindow::eventFilter(obj, event);
      }
}

Notice in the example above that unhandled events are passed to the base class's eventFilter() function, since the base class might have reimplemented eventFilter() for its own internal purposes.

Warning: If you delete the receiver object in this function, be sure to return true. Otherwise, Qt will forward the event to the deleted object and the program might crash.

layout->inherits(“QLayoutItem”);    // returns true (even though QLayoutItem is not a QObject)

If you need to determine whether an object is an instance of a particular class for the purpose of casting it, consider using qobject_cast<Type *>(object) instead.

See also metaObject() and qobject_cast().

pub unsafe fn install_event_filter( &self, filter_obj: impl CastInto<Ptr<QObject>>, )

Installs an event filter filterObj on this object. For example:

Calls C++ function: void QObject::installEventFilter(QObject* filterObj).

C++ documentation:

Installs an event filter filterObj on this object. For example:

  monitoredObj->installEventFilter(filterObj);

An event filter is an object that receives all events that are sent to this object. The filter can either stop the event or forward it to this object. The event filter filterObj receives events via its eventFilter() function. The eventFilter() function must return true if the event should be filtered, (i.e. stopped); otherwise it must return false.

If multiple event filters are installed on a single object, the filter that was installed last is activated first.

Here's a KeyPressEater class that eats the key presses of its monitored objects:

class KeyPressEater : public QObject
{
      Q_OBJECT
      ...
protected:
      bool eventFilter(QObject obj, QEvent event);
};
bool KeyPressEater::eventFilter(QObject obj, QEvent event)
{
      if (event->type() == QEvent::KeyPress) {
          QKeyEvent keyEvent = static_cast<QKeyEvent >(event);
          qDebug(“Ate key press %d”, keyEvent->key());
          return true;
      } else {
          // standard event processing
          return QObject::eventFilter(obj, event);
      }
}

And here's how to install it on two widgets:

KeyPressEater keyPressEater = new KeyPressEater(this);
QPushButton pushButton = new QPushButton(this);
QListView *listView = new QListView(this);
pushButton->installEventFilter(keyPressEater);
listView->installEventFilter(keyPressEater);

The QShortcut class, for example, uses this technique to intercept shortcut key presses.

Warning: If you delete the receiver object in your eventFilter() function, be sure to return true. If you return false, Qt sends the event to the deleted object and the program will crash.

Note that the filtering object must be in the same thread as this object. If filterObj is in a different thread, this function does nothing. If either filterObj or this object are moved to a different thread after calling this function, the event filter will not be called until both objects have the same thread affinity again (it is not removed).

See also removeEventFilter(), eventFilter(), and event().

pub unsafe fn is_widget_type(&self) -> bool

Returns true if the object is a widget; otherwise returns false.

Calls C++ function: bool QObject::isWidgetType() const.

C++ documentation:

Returns true if the object is a widget; otherwise returns false.

Calling this function is equivalent to calling inherits("QWidget"), except that it is much faster.

pub unsafe fn is_window_type(&self) -> bool

Returns true if the object is a window; otherwise returns false.

Calls C++ function: bool QObject::isWindowType() const.

C++ documentation:

Returns true if the object is a window; otherwise returns false.

Calling this function is equivalent to calling inherits("QWindow"), except that it is much faster.

pub unsafe fn kill_timer(&self, id: i32)

Kills the timer with timer identifier, id.

Calls C++ function: void QObject::killTimer(int id).

C++ documentation:

Kills the timer with timer identifier, id.

The timer identifier is returned by startTimer() when a timer event is started.

See also timerEvent() and startTimer().

pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>

Returns a pointer to the meta-object of this object.

Calls C++ function: virtual const QMetaObject* QObject::metaObject() const.

C++ documentation:

Returns a pointer to the meta-object of this object.

A meta-object contains information about a class that inherits QObject, e.g. class name, superclass name, properties, signals and slots. Every QObject subclass that contains the Q_OBJECT macro will have a meta-object.

The meta-object information is required by the signal/slot connection mechanism and the property system. The inherits() function also makes use of the meta-object.

If you have no pointer to an actual object instance but still want to access the meta-object of a class, you can use staticMetaObject.

Example:

QObject *obj = new QPushButton;
obj->metaObject()->className();             // returns “QPushButton”
QPushButton::staticMetaObject.className();  // returns “QPushButton”

See also staticMetaObject.

pub unsafe fn move_to_thread(&self, thread: impl CastInto<Ptr<QThread>>)

Changes the thread affinity for this object and its children. The object cannot be moved if it has a parent. Event processing will continue in the targetThread.

Calls C++ function: void QObject::moveToThread(QThread* thread).

C++ documentation:

Changes the thread affinity for this object and its children. The object cannot be moved if it has a parent. Event processing will continue in the targetThread.

To move an object to the main thread, use QApplication::instance() to retrieve a pointer to the current application, and then use QApplication::thread() to retrieve the thread in which the application lives. For example:

myObject->moveToThread(QApplication::instance()->thread());

If targetThread is zero, all event processing for this object and its children stops.

Note that all active timers for the object will be reset. The timers are first stopped in the current thread and restarted (with the same interval) in the targetThread. As a result, constantly moving an object between threads can postpone timer events indefinitely.

A QEvent::ThreadChange event is sent to this object just before the thread affinity is changed. You can handle this event to perform any special processing. Note that any new events that are posted to this object will be handled in the targetThread.

Warning: This function is not thread-safe; the current thread must be same as the current thread affinity. In other words, this function can only "push" an object from the current thread to another thread, it cannot "pull" an object from any arbitrary thread to the current thread.

See also thread().

pub unsafe fn object_name(&self) -> CppBox<QString>

This property holds the name of this object

Calls C++ function: QString QObject::objectName() const.

C++ documentation:

This property holds the name of this object

You can find an object by name (and type) using findChild(). You can find a set of objects with findChildren().

qDebug(“MyClass::setPrecision(): (%s) invalid precision %f”,
         qPrintable(objectName()), newPrecision);

By default, this property contains an empty string.

Access functions:

QString	objectName() const
void	setObjectName(const QString &name)

Notifier signal:

void

objectNameChanged(const QString &objectName)

[see note below]

Note: This is a private signal. It can be used in signal connections but cannot be emitted by the user.

See also metaObject() and QMetaObject::className().

pub unsafe fn parent(&self) -> QPtr<QObject>

Returns a pointer to the parent object.

Calls C++ function: QObject* QObject::parent() const.

C++ documentation:

Returns a pointer to the parent object.

See also setParent() and children().

pub unsafe fn property(&self, name: *const i8) -> CppBox<QVariant>

Returns the value of the object's name property.

Calls C++ function: QVariant QObject::property(const char* name) const.

C++ documentation:

Returns the value of the object’s name property.

If no such property exists, the returned variant is invalid.

Information about all available properties is provided through the metaObject() and dynamicPropertyNames().

See also setProperty(), QVariant::isValid(), metaObject(), and dynamicPropertyNames().

pub unsafe fn qt_metacall( &self, arg1: Call, arg2: i32, arg3: *mut *mut c_void, ) -> i32

Calls C++ function: virtual int QObject::qt_metacall(QMetaObject::Call arg1, int arg2, void** arg3).

pub unsafe fn qt_metacast(&self, arg1: *const i8) -> *mut c_void

Calls C++ function: virtual void* QObject::qt_metacast(const char* arg1).

pub unsafe fn remove_event_filter(&self, obj: impl CastInto<Ptr<QObject>>)

Removes an event filter object obj from this object. The request is ignored if such an event filter has not been installed.

Calls C++ function: void QObject::removeEventFilter(QObject* obj).

C++ documentation:

Removes an event filter object obj from this object. The request is ignored if such an event filter has not been installed.

All event filters for this object are automatically removed when this object is destroyed.

It is always safe to remove an event filter, even during event filter activation (i.e. from the eventFilter() function).

See also installEventFilter(), eventFilter(), and event().

pub unsafe fn set_object_name(&self, name: impl CastInto<Ref<QString>>)

This property holds the name of this object

Calls C++ function: void QObject::setObjectName(const QString& name).

C++ documentation:

This property holds the name of this object

You can find an object by name (and type) using findChild(). You can find a set of objects with findChildren().

qDebug(“MyClass::setPrecision(): (%s) invalid precision %f”,
         qPrintable(objectName()), newPrecision);

By default, this property contains an empty string.

Access functions:

QString	objectName() const
void	setObjectName(const QString &name)

Notifier signal:

void

objectNameChanged(const QString &objectName)

[see note below]

Note: This is a private signal. It can be used in signal connections but cannot be emitted by the user.

See also metaObject() and QMetaObject::className().

pub unsafe fn set_parent(&self, parent: impl CastInto<Ptr<QObject>>)

Makes the object a child of parent.

Calls C++ function: void QObject::setParent(QObject* parent).

C++ documentation:

Makes the object a child of parent.

See also parent() and children().

pub unsafe fn set_property( &self, name: *const i8, value: impl CastInto<Ref<QVariant>>, ) -> bool

Sets the value of the object's name property to value.

Calls C++ function: bool QObject::setProperty(const char* name, const QVariant& value).

C++ documentation:

Sets the value of the object’s name property to value.

If the property is defined in the class using Q_PROPERTY then true is returned on success and false otherwise. If the property is not defined using Q_PROPERTY, and therefore not listed in the meta-object, it is added as a dynamic property and false is returned.

Information about all available properties is provided through the metaObject() and dynamicPropertyNames().

Dynamic properties can be queried again using property() and can be removed by setting the property value to an invalid QVariant. Changing the value of a dynamic property causes a QDynamicPropertyChangeEvent to be sent to the object.

Note: Dynamic properties starting with "_q_" are reserved for internal purposes.

See also property(), metaObject(), dynamicPropertyNames(), and QMetaProperty::write().

pub unsafe fn signals_blocked(&self) -> bool

Returns true if signals are blocked; otherwise returns false.

Calls C++ function: bool QObject::signalsBlocked() const.

C++ documentation:

Returns true if signals are blocked; otherwise returns false.

Signals are not blocked by default.

See also blockSignals() and QSignalBlocker.

pub unsafe fn start_timer_2a(&self, interval: i32, timer_type: TimerType) -> i32

Starts a timer and returns a timer identifier, or returns zero if it could not start a timer.

Calls C++ function: int QObject::startTimer(int interval, Qt::TimerType timerType = …).

C++ documentation:

Starts a timer and returns a timer identifier, or returns zero if it could not start a timer.

A timer event will occur every interval milliseconds until killTimer() is called. If interval is 0, then the timer event occurs once every time there are no more window system events to process.

The virtual timerEvent() function is called with the QTimerEvent event parameter class when a timer event occurs. Reimplement this function to get timer events.

If multiple timers are running, the QTimerEvent::timerId() can be used to find out which timer was activated.

Example:

class MyObject : public QObject
{
      Q_OBJECT
public:
      MyObject(QObject *parent = 0);
protected:
      void timerEvent(QTimerEvent *event);
};
MyObject::MyObject(QObject *parent)
      : QObject(parent)
{
      startTimer(50);     // 50-millisecond timer
      startTimer(1000);   // 1-second timer
      startTimer(60000);  // 1-minute timer
      using namespace std::chrono;
      startTimer(milliseconds(50));
      startTimer(seconds(1));
      startTimer(minutes(1));
      // since C++14 we can use std::chrono::duration literals, e.g.:
      startTimer(100ms);
      startTimer(5s);
      startTimer(2min);
      startTimer(1h);
}
void MyObject::timerEvent(QTimerEvent *event)
{
      qDebug() << “Timer ID:” << event->timerId();
}

Note that QTimer's accuracy depends on the underlying operating system and hardware. The timerType argument allows you to customize the accuracy of the timer. See Qt::TimerType for information on the different timer types. Most platforms support an accuracy of 20 milliseconds; some provide more. If Qt is unable to deliver the requested number of timer events, it will silently discard some.

The QTimer class provides a high-level programming interface with single-shot timers and timer signals instead of events. There is also a QBasicTimer class that is more lightweight than QTimer and less clumsy than using timer IDs directly.

See also timerEvent(), killTimer(), and QTimer::singleShot().

pub unsafe fn start_timer_1a(&self, interval: i32) -> i32

Starts a timer and returns a timer identifier, or returns zero if it could not start a timer.

};
MyObject::MyObject(QObject *parent)
      : QObject(parent)
{
      startTimer(50);     // 50-millisecond timer
      startTimer(1000);   // 1-second timer
      startTimer(60000);  // 1-minute timer
      using namespace std::chrono;
      startTimer(milliseconds(50));
      startTimer(seconds(1));
      startTimer(minutes(1));
      // since C++14 we can use std::chrono::duration literals, e.g.:
      startTimer(100ms);
