Struct qt_widgets::QGraphicsObject

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

The QGraphicsObject class provides a base class for all graphics items that require signals, slots and properties.

C++ class: QGraphicsObject.

C++ documentation:

The QGraphicsObject class provides a base class for all graphics items that require signals, slots and properties.

The class extends a QGraphicsItem with QObject's signal/slot and property mechanisms. It maps many of QGraphicsItem's basic setters and getters to properties and adds notification signals for many of them.
