QSGBasicGeometryNode ¶

概要 ¶

详细描述 ¶

QSGBasicGeometryNode class should not be used by itself. It is only encapsulates shared functionality between the QSGGeometryNode and QSGClipNode 类。

注意

All classes with QSG prefix should be used solely on the scene graph’s rendering thread. See 场景图形和渲染 了解更多信息。

class QSGBasicGeometryNode ( type ) ¶

param type

NodeType

Creates a new basic geometry node of type type

PySide2.QtQuick.QSGBasicGeometryNode. clipList ( ) ¶

返回类型

QSGClipNode

PySide2.QtQuick.QSGBasicGeometryNode. geometry ( ) ¶

返回类型

QSGGeometry

Returns this node’s geometry.

The geometry is null by default.

setGeometry()

PySide2.QtQuick.QSGBasicGeometryNode. matrix ( ) ¶

返回类型

QMatrix4x4

PySide2.QtQuick.QSGBasicGeometryNode. setGeometry ( geometry ) ¶

参数

geometry – QSGGeometry

Sets the geometry of this node to geometry .

If the node has the flag OwnsGeometry set, it will also delete the geometry object it is pointing to. This flag is not set by default.

If the geometry is changed without calling again, the user must also mark the geometry as dirty using markDirty() .

参数

c – QSGClipNode

PySide2.QtQuick.QSGBasicGeometryNode. setRendererMatrix ( m ) ¶

参数

m – QMatrix4x4
