Struct qt_widgets::QGraphicsLayoutItem

#[repr(C)]
pub struct QGraphicsLayoutItem { /* fields omitted */ }

The QGraphicsLayoutItem class can be inherited to allow your custom items to be managed by layouts.

C++ class: QGraphicsLayoutItem.

C++ documentation:

The QGraphicsLayoutItem class can be inherited to allow your custom items to be managed by layouts.

QGraphicsLayoutItem is an abstract class that defines a set of virtual functions describing sizes, size policies, and size hints for any object arranged by QGraphicsLayout. The API contains functions relevant for both the item itself and for the user of the item as most of QGraphicsLayoutItem's functions are also part of the subclass' public API.

In most cases, existing layout-aware classes such as QGraphicsWidget and QGraphicsLayout already provide the functionality you require. However, subclassing these classes will enable you to create both graphical elements that work well with layouts (QGraphicsWidget) or custom layouts (QGraphicsLayout).

Methods

impl QGraphicsLayoutItem

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

Returns the contents rect in local coordinates.

Calls C++ function: QRectF QGraphicsLayoutItem::contentsRect() const.

C++ documentation:

Returns the contents rect in local coordinates.

The contents rect defines the subrectangle used by an associated layout when arranging subitems. This function is a convenience function that adjusts the item's geometry() by its contents margins. Note that getContentsMargins() is a virtual function that you can reimplement to return the item's contents margins.

See also getContentsMargins() and geometry().

pub unsafe fn effective_size_hint_2a(
    &self,
    which: SizeHint,
    constraint: impl CastInto<Ref<QSizeF>>
) -> CppBox<QSizeF>

Returns the effective size hint for this QGraphicsLayoutItem.

Calls C++ function: QSizeF QGraphicsLayoutItem::effectiveSizeHint(Qt::SizeHint which, const QSizeF& constraint = …) const.

C++ documentation:

Returns the effective size hint for this QGraphicsLayoutItem.

which is the size hint in question. constraint is an optional argument that defines a special constrain when calculating the effective size hint. By default, constraint is QSizeF(-1, -1), which means there is no constraint to the size hint.

If you want to specify the widget's size hint for a given width or height, you can provide the fixed dimension in constraint. This is useful for widgets that can grow only either vertically or horizontally, and need to set either their width or their height to a special value.

For example, a text paragraph item fit into a column width of 200 may grow vertically. You can pass QSizeF(200, -1) as a constraint to get a suitable minimum, preferred and maximum height).

You can adjust the effective size hint by reimplementing sizeHint() in a QGraphicsLayoutItem subclass, or by calling one of the following functions: setMinimumSize(), setPreferredSize, or setMaximumSize() (or a combination of both).

This function caches each of the size hints and guarantees that sizeHint() will be called only once for each value of which - unless constraint is not specified and updateGeometry() has been called.

See also sizeHint().

pub unsafe fn effective_size_hint_1a(&self, which: SizeHint) -> CppBox<QSizeF>

See also setMinimumWidth(), setMinimumSize(), and minimumSize().

pub unsafe fn owned_by_layout(&self) -> bool

Returns whether a layout should delete this item in its destructor. If its true, then the layout will delete it. If its false, then it is assumed that another object has the ownership of it, and the layout won't delete this item.

Calls C++ function: bool QGraphicsLayoutItem::ownedByLayout() const.

C++ documentation:

Returns whether a layout should delete this item in its destructor. If its true, then the layout will delete it. If its false, then it is assumed that another object has the ownership of it, and the layout won't delete this item.

If the item inherits both QGraphicsItem and QGraphicsLayoutItem (such as QGraphicsWidget does) the item is really part of two ownership hierarchies. This property informs what the layout should do with its child items when it is destructed. In the case of QGraphicsWidget, it is preferred that when the layout is deleted it won't delete its children (since they are also part of the graphics item hierarchy).

By default this value is initialized to false in QGraphicsLayoutItem, but it is overridden by QGraphicsLayout to return true. This is because QGraphicsLayout is not normally part of the QGraphicsItem hierarchy, so the parent layout should delete it. Subclasses might override this default behaviour by calling setOwnedByLayout(true).

This function was introduced in Qt 4.6.

See also setOwnedByLayout().

pub unsafe fn parent_layout_item(&self) -> MutPtr<QGraphicsLayoutItem>

Returns the parent of this QGraphicsLayoutItem, or 0 if there is no parent, or if the parent does not inherit from QGraphicsLayoutItem (QGraphicsLayoutItem is often used through multiple inheritance with QObject-derived classes).

Calls C++ function: QGraphicsLayoutItem* QGraphicsLayoutItem::parentLayoutItem() const.

C++ documentation:

Returns the parent of this QGraphicsLayoutItem, or 0 if there is no parent, or if the parent does not inherit from QGraphicsLayoutItem (QGraphicsLayoutItem is often used through multiple inheritance with QObject-derived classes).

See also setParentLayoutItem().

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

This virtual function sets the geometry of the QGraphicsLayoutItem to rect, which is in parent coordinates (e.g., the top-left corner of rect is equivalent to the item's position in parent coordinates).

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

C++ documentation:

This virtual function sets the geometry of the QGraphicsLayoutItem to rect, which is in parent coordinates (e.g., the top-left corner of rect is equivalent to the item's position in parent coordinates).

You must reimplement this function in a subclass of QGraphicsLayoutItem to receive geometry updates. The layout will call this function when it does a rearrangement.

If rect is outside of the bounds of minimumSize and maximumSize, it will be adjusted to its closest size so that it is within the legal bounds.
