示例1: Start
public void Start (PaintEventArgs pe) {
// We need to get the graphics for every paint.
real_graphics.Push(pe.SetGraphics (XplatUI.GetOffscreenGraphics (back_buffer)));
}示例2: End
public void End (PaintEventArgs pe) {
Graphics buffered_graphics;
buffered_graphics = pe.SetGraphics ((Graphics) real_graphics.Pop ());
if (pending_disposal)
Dispose ();
else {
XplatUI.BlitFromOffscreen (parent.Handle, pe.Graphics, back_buffer, buffered_graphics, pe.ClipRectangle);
