virtual bool

updateTexture () = 0

详细描述

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

[pure virtual] bool QSGDynamicTexture:: updateTexture ()

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 QQuickItem::updatePaintNode () 或 QSGNode::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.
