Sad I occured a problem ,which is that I want to realize not to redraw background color when I moved something in the ClientRect, just as the Windows standard message BOOL OnEraseBackground(),For example,if I do that

BOOL OnEraseBackground()
{
return FALSE;
}

, when I move something in the ClientRect, the windows system call the funtion of OnDraw(), which can not to redraw the background color,who can tell me how to do that with symbian?
