To update the content of the texture, call updateTexture() explicitly.

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.

Member Function Documentation

[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.

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