Detailed Description#

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.

Parents and Children#

Each graphics object can be constructed with a parent item. This ensures that the item will be destroyed when its parent item is destroyed. Although QGraphicsObject inherits from both QObject and QGraphicsItem , you should use the functions provided by QGraphicsItem , not QObject , to manage the relationships between parent and child items.

The relationships between items can be explored using the parentItem() and childItems() functions. In the hierarchy of items in a scene, the parentObject() and parentWidget() functions are the equivalent of the parent() and parentWidget() functions for QWidget subclasses.

class PySide6.QtWidgets.QGraphicsObject([parent=None])#

Parameters:: parent – PySide6.QtWidgets.QGraphicsItem

Constructs a QGraphicsObject with parent.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.QtWidgets.QGraphicsObject.effect: PySide6.QtWidgets.QGraphicsEffect#

This property holds the effect attached to this item.

See also

setGraphicsEffect() graphicsEffect()

Access functions:

property PᅟySide6.QtWidgets.QGraphicsObject.enabled: bool#

This property holds whether the item is enabled or not.

This property is declared in QGraphicsItem .

By default, this property is true.

See also

isEnabled() setEnabled()

Access functions:

Signal enabledChanged ()

property PᅟySide6.QtWidgets.QGraphicsObject.opacity: float#

This property holds the opacity of the item.

See also

setOpacity() opacity()

Access functions:

Signal opacityChanged ()

property PᅟySide6.QtWidgets.QGraphicsObject.parent: PySide6.QtWidgets.QGraphicsObject#

This property holds the parent of the item.

Note

The item’s parent is set independently of the parent object returned by parent() .
