Detailed Description

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

Since: 4.4

\inmodule QtWidgets

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:

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).

◆ createProxyForChildWidget()

QGraphicsProxyWidget * QGraphicsProxyWidget::createProxyForChildWidget ( QWidget * child )

Since: 4.5

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.

◆ newProxyWidget

QGraphicsProxyWidget * QGraphicsProxyWidget::newProxyWidget ( const QWidget * child )

protectedslot

Since: 4.5

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.

Here is the call graph for this function:

◆ setWidget()

void QGraphicsProxyWidget::setWidget ( QWidget * 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 \nullptr.

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 \nullptr 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 QOpenGLWidget and QAxWidget.

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