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.
This class cannot directly be used in applications. It rather serves as a base for subclasses like
- class PySide6.QtGui.QPaintDeviceWindow¶
Marks the entire window as dirty and schedules a repaint.
Subsequent calls to this function before the next paint event will get ignored.
For non-exposed windows the update is deferred until the window becomes exposed again.
