QSGDynamicTexture ¶

详细描述 ¶

To update the content of the texture, call updateTexture() explicitly. Simply calling bind() will not update the texture.

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 QSGDynamicTexture ¶

PySide2.QtQuick.QSGDynamicTexture. updateTexture ( ) ¶

返回类型

bool

Call this function to explicitly update the dynamic texture.

The function returns true if the texture was changed as a resul of the update; otherwise returns false.

注意

This function is typically called from updatePaintNode() or preprocess() , meaning during the synchronization 或 node preprocessing phases of the scenegraph. Calling it at other times is discouraged and can lead to unexpected behavior.
