Detailed Description#
QPaintDeviceWindow is like a regular QWindow , with the added functionality of being a paint device too. Whenever the content needs to be updated, the virtual paintEvent() function is called. Subclasses, that reimplement this function, can then simply open a QPainter on the window.
Note
This class cannot directly be used in applications. It rather serves as a base for subclasses like QOpenGLWindow .
