You just need to implement the necessary mouse event handling by overwriting MyWidget's mousePressEvent(), mouseMoveEvent() and mouseReleaseEvent() handlers.

1. Detect the mouse down, get current mouse position
2. While moving, get current mouse position, calculate difference, save new position, move window by diff

You can get the window (top level widget) from inside MyWidget through the window() method.
