Accepted Answer

The onPaint event or method in many windowing systems is triggered when a window needs to be repainted. This can happen for various reasons, such as when a window is first displayed, when it is resized, or when it is uncovered after being hidden behind other windows. The purpose of this event is to redraw the contents of the window to ensure that the display is up-to-date and correctly rendered.
