Class QtComponentGraphics


public class QtComponentGraphics
extends QtGraphics

QtComponentPainter is a Graphics2D context for painting directly to AWT components. They require an existing QPainter object (the one passed into the native paint method), and are created there (ONLY). Since this context does direct on-screen drawing it is NOT thread-safe, and should NOT be used outside the thread in which it was created. In other words, this is intended for use by QtComponentPeer.paintEvent() only.
