Detailed Description

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

Since: 4.6

\inmodule QtWidgets

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.

Property Documentation

◆ enabled

QGraphicsObject::enabled

readwrite

whether the item is enabled or not

This property is declared in QGraphicsItem.

By default, this property is true.

See also: QGraphicsItem::isEnabled(), QGraphicsItem::setEnabled()

Definition at line 467 of file qgraphicsitem.h.

◆ opacity

QGraphicsObject::opacity

readwrite

the opacity of the item

See also: QGraphicsItem::setOpacity(), QGraphicsItem::opacity()

Definition at line 467 of file qgraphicsitem.h.

◆ parent

QGraphicsObject::parent

readwrite

the parent of the item

Note: The item's parent is set independently of the parent object returned by QObject::parent().

See also: QGraphicsItem::setParentItem(), QGraphicsItem::parentObject()

Definition at line 467 of file qgraphicsitem.h.

◆ pos

QGraphicsObject::pos

readwrite

the position of the item

Describes the items position.

See also: QGraphicsItem::setPos(), QGraphicsItem::pos()

Definition at line 467 of file qgraphicsitem.h.

◆ rotation

QGraphicsObject::rotation

readwrite

the rotation of the item in degrees.

This specifies how many degrees to rotate the item around its transformOrigin. The default rotation is 0 degrees (i.e. not rotated at all).

Definition at line 467 of file qgraphicsitem.h.

◆ scale

QGraphicsObject::scale

readwrite

the scale of the item.

A scale of less than 1 means the item will be displayed smaller than normal, and a scale of greater than 1 means the item will be displayed larger than normal. A negative scale means the item will be mirrored.

By default, items are displayed at a scale of 1 (i.e. at their normal size).

Scaling is from the item's transformOrigin.

Definition at line 467 of file qgraphicsitem.h.

◆ transformOriginPoint

QGraphicsObject::transformOriginPoint

readwrite

the transformation origin

This property sets a specific point in the item's coordinate system as the origin for scale and rotation.

See also: scale, rotation, QGraphicsItem::transformOriginPoint()

Definition at line 467 of file qgraphicsitem.h.

◆ visible

QGraphicsObject::visible

readwrite

whether the item is visible or not

This property is declared in QGraphicsItem.

By default, this property is true.

See also: QGraphicsItem::isVisible(), QGraphicsItem::setVisible()

Definition at line 467 of file qgraphicsitem.h.

◆ x

QGraphicsObject::x

readwrite

the x position of the item

Describes the items x position.

See also: QGraphicsItem::setX(), setPos()

Definition at line 467 of file qgraphicsitem.h.

◆ y

QGraphicsObject::y

readwrite

the y position of the item

Describes the items y position.

See also: QGraphicsItem::setY(), setPos()

Definition at line 467 of file qgraphicsitem.h.

◆ z

QGraphicsObject::z

readwrite

the z value of the item

Describes the items z value.

See also: QGraphicsItem::setZValue(), zValue()
