QSGClipNode

The QSGClipNode class implements the clipping functionality in the scene graph. More

Synopsis

Functions

Detailed Description

Clipping applies to the node’s subtree and can be nested. Multiple clip nodes will be accumulated by intersecting all their geometries. The accumulation happens as part of the rendering.

Clip nodes must have a geometry before they can be added to the scene graph.

Clipping is usually implemented by using the stencil buffer.

Note

All classes with QSG prefix should be used solely on the scene graph’s rendering thread. See Scene Graph and Rendering for more information.

class PySide2.QtQuick.QSGClipNode

Creates a new QSGClipNode without a geometry.

The clip node must have a geometry before it can be added to the scene graph.

PySide2.QtQuick.QSGClipNode.clipRect()
Return type

PySide2.QtCore.QRectF

Returns the clip rect of this node.

setClipRect()

PySide2.QtQuick.QSGClipNode.isRectangular()
Return type

bool

Returns if this clip node has a rectangular clip.

PySide2.QtQuick.QSGClipNode.setClipRect(arg__1)
Parameters

arg__1PySide2.QtCore.QRectF

Sets the clip rect of this clip node to rect .

When a rectangular clip is set in combination with setIsRectangular the renderer may in some cases use a more optimal clip method.

clipRect()

PySide2.QtQuick.QSGClipNode.setIsRectangular(rectHint)
Parameters

rectHint – bool

Sets whether this clip node has a rectangular clip to rectHint .

This is an optimization hint which means that the renderer can use scissoring instead of stencil, which is significantly faster.

When this hint is set and it is applicable, the clip region will be generated from clipRect() rather than geometry() .

By default this property is false .
