Struct QGraphicsSceneResizeEvent

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

The QGraphicsSceneResizeEvent class provides events for widget resizing in the graphics view framework.

C++ class: QGraphicsSceneResizeEvent.

C++ documentation:

The QGraphicsSceneResizeEvent class provides events for widget resizing in the graphics view framework.

A QGraphicsWidget sends itself a QGraphicsSceneResizeEvent immediately when its geometry changes.

It's similar to QResizeEvent, but its sizes, oldSize() and newSize(), use QSizeF instead of QSize.

Implementations

impl QGraphicsSceneResizeEvent

pub unsafe fn new() -> CppBox<QGraphicsSceneResizeEvent>

Constructs a QGraphicsSceneResizeEvent.

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

C++ documentation:

Constructs a QGraphicsSceneResizeEvent.

pub unsafe fn new_size(&self) -> CppBox<QSizeF>

Returns the new size (i.e., the current size).

Calls C++ function: QSizeF QGraphicsSceneResizeEvent::newSize() const.

C++ documentation:

Returns the new size (i.e., the current size).

See also oldSize() and QGraphicsWidget::resize().

pub unsafe fn old_size(&self) -> CppBox<QSizeF>

Returns the old size (i.e., the size immediately before the widget was resized).

Calls C++ function: QSizeF QGraphicsSceneResizeEvent::oldSize() const.

C++ documentation:

Returns the old size (i.e., the size immediately before the widget was resized).

See also newSize() and QGraphicsWidget::resize().

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

Calls C++ function: void QGraphicsSceneResizeEvent::setNewSize(const QSizeF& size).

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

Calls C++ function: void QGraphicsSceneResizeEvent::setOldSize(const QSizeF& size).

Methods from Deref<Target = QGraphicsSceneEvent>

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

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

pub unsafe fn widget(&self) -> QPtr<QWidget>

Returns the widget where the event originated, or 0 if the event originates from another application.

Calls C++ function: QWidget* QGraphicsSceneEvent::widget() const.

C++ documentation:

Returns the widget where the event originated, or 0 if the event originates from another application.

Methods from Deref<Target = QEvent>

pub unsafe fn accept(&self)

Sets the accept flag of the event object, the equivalent of calling setAccepted(true).

Calls C++ function: void QEvent::accept().

C++ documentation:

Sets the accept flag of the event object, the equivalent of calling setAccepted(true).

Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget.

See also ignore().

pub unsafe fn copy_from(&self, other: impl CastInto<Ref<QEvent>>) -> Ref<QEvent>

Calls C++ function: QEvent& QEvent::operator=(const QEvent& other).

pub unsafe fn ignore(&self)

Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).

Calls C++ function: void QEvent::ignore().

C++ documentation:

Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).

Clearing the accept parameter indicates that the event receiver does not want the event. Unwanted events might be propagated to the parent widget.

See also accept().

pub unsafe fn is_accepted(&self) -> bool

the accept flag of the event object

Calls C++ function: bool QEvent::isAccepted() const.

C++ documentation:

the accept flag of the event object

Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget. By default, isAccepted() is set to true, but don't rely on this as subclasses may choose to clear it in their constructor.

For convenience, the accept flag can also be set with accept(), and cleared with ignore().

Access functions:

bool	isAccepted() const
void	setAccepted(bool accepted)

pub unsafe fn set_accepted(&self, accepted: bool)

the accept flag of the event object

Calls C++ function: void QEvent::setAccepted(bool accepted).

C++ documentation:

the accept flag of the event object

Setting the accept parameter indicates that the event receiver wants the event. Unwanted events might be propagated to the parent widget. By default, isAccepted() is set to true, but don't rely on this as subclasses may choose to clear it in their constructor.

For convenience, the accept flag can also be set with accept(), and cleared with ignore().

Access functions:

bool	isAccepted() const
void	setAccepted(bool accepted)

pub unsafe fn spontaneous(&self) -> bool

Returns true if the event originated outside the application (a system event); otherwise returns false.

Calls C++ function: bool QEvent::spontaneous() const.

C++ documentation:

Returns true if the event originated outside the application (a system event); otherwise returns false.

The return value of this function is not defined for paint events.

pub unsafe fn type_(&self) -> Type

Returns the event type.

Calls C++ function: QEvent::Type QEvent::type() const.

C++ documentation:

Returns the event type.
