QGraphicsProxyWidget Class Reference
|
QWidget state | QGraphicsProxyWidget state | Notes |
---|---|---|
QWidget::enabled | QGraphicsProxyWidget::enabled | |
QWidget::visible | QGraphicsProxyWidget::visible | The explicit state is also symmetric. |
QWidget::geometry | QGraphicsProxyWidget::geometry | Geometry is only guaranteed to be symmetric while the embedded widget is visible. |
QWidget::layoutDirection | QGraphicsProxyWidget::layoutDirection | |
QWidget::style | QGraphicsProxyWidget::style | |
QWidget::palette | QGraphicsProxyWidget::palette | |
QWidget::font | QGraphicsProxyWidget::font | |
QWidget::cursor | QGraphicsProxyWidget::cursor | The embedded widget overrides the proxy widget cursor. The proxy cursor changes depending on which embedded subwidget is currently under the mouse. |
QWidget::sizeHint() | QGraphicsProxyWidget::sizeHint() | All size hint functionality from the embedded widget is forwarded by the proxy. |
QWidget::getContentsMargins() | QGraphicsProxyWidget::getContentsMargins() | Updated once by setWidget(). |
QWidget::windowTitle | QGraphicsProxyWidget::windowTitle | Updated once by setWidget(). |
Note: QGraphicsScene keeps the embedded widget in a special state that prevents it from disturbing other widgets (both embedded and not embedded) while the widget is embedded. In this state, the widget may differ slightly in behavior from when it is not embedded.
See also QGraphicsScene::addWidget() and QGraphicsWidget.
Constructs a new QGraphicsProxy widget. parent and wFlags are passed to QGraphicsItem's constructor.
Destroys the proxy widget and any embedded widget.
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.
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.
See also widget().
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().
Returns a pointer to the embedded widget.
See also setWidget().
