Hi,
I'm running nano-x, nxlib and fltk 1.1.9 on an ARM AT91SAM9263.
I found a Problem with showing GIF-Images with the FLTK-supplied image
library on Fl_Double_Windows. It works on Fl_Single_Windows. The cause for
the problem is the difference in clipping handling of nano-x between pixmaps
(the buffered window) and actual windows. The clipping code for pixmaps in
nano-x doesn't take offsets (GrSetGCClipOrigin) into account. Therefore I
changed the file srvutil.c (l. 962):
#if DYNAMICREGIONS
reg = GdAllocRectRegion(0, 0, pp->psd->xvirtres, pp->psd->yvirtres);
/* intersect with user region if any*/
if (gcp->regionid) {
regionp = GsFindRegion(gcp->regionid);
if (regionp) {
if (gcp->xoff || gcp->yoff) { //offset for pixmaps (ScJ)
MWCLIPREGION *local = GdAllocRegion();
GdCopyRegion(local, regionp->rgn);
GdOffsetRegion(local, gcp->xoff, gcp->yoff);
GdIntersectRegion(reg, reg, local);
GdDestroyRegion(local);
} else {
GdIntersectRegion(reg, reg, regionp->rgn);
}
}
}
GdSetClipRegion(pp->psd, reg);
#else
Any comments welcome.
Regards,
Johannes Schock
