I don't know if these unimplemented Maskblt calls are related
to your toolbar problem - Normal toolbar don't use Maskblt and
most programs using toolbars display fine.
Here is the Wine 'implementation' of MaskBlt :
BOOL WINAPI MaskBlt(HDC hdcDest, INT nXDest, INT nYDest,
INT nWidth, INT nHeight, HDC hdcSource,
INT nXSrc, INT nYSrc, HBITMAP hbmMask,
INT xMask, INT yMask, DWORD dwRop)
{
FIXME("(%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%d,%ld): stub\n",
hdcDest,nXDest,nYDest,nWidth,nHeight,hdcSource,nXSrc,nYSrc,
hbmMask,xMask,yMask,dwRop);
return 1;
}
as you can see, the stub info message displays that the
missing graphic has 210 pixels x 24 : this could be a frame
for a custom toolbar, but not a button I think.
Now, about implementing MaskBlt : this is not impossible of course -
IIRC MaskBlt should get the bulk of functionnality of existing BitBlt,
just adding a mask ;-). Then BitBlt should call down to MaskBlt.
Unfortunately, BitBlt is a bit complex :-)
Take a look at graphics/x11drv/bitblt.c. This is bitblt for X 'device
context'. If you can read and understand it easily, you will not have
any problem fixing this old problem.
