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
