I am having a problem with off screen drawing. When I try to use on off
screen PixMap and then copy it to the on screen window I get nothing but
a grey window.
I have a window called on screen and a get a NewPixMap when I initialize
this windows. I do not get a new pixMap after the copy since I didn't
see in anything in the docs where it said that the old one was disposed of.
void updateDisplay(void){
GrClearWindow(offscreenwid,0);
GrText(offscreenwid, m_gc, 0, y, stda, -1, GR_TFASCII);
GrCopyArea(m_onscreenwid, m_gc, 0, 0, 640, 210, offscreenwid,
0,0,MWROP_USE_GC_MODE);
GrFlush();
}
This works just fine as would be expected
void updateDisplay(void){
GrClearWindow(onscreenwid,0);
GrText(onscreenwid, m_gc, 0, y, stda, -1, GR_TFASCII);
//GrCopyArea(m_onscreenwid, m_gc, 0, 0, 640, 210, offscreenwid,
0,0,MWROP_USE_GC_MODE);
GrFlush();
}
Any ideas?
