Hi,
Am porting OO to directfb and am facing a problem with the slideshow engine
wherein on PgDown the navigation of slides doesnt seem to be happening.After
a lot of debugging ive realised an inconsistent output from the
gdk_draw_drawable() api I am using in the GtkCopyBits function. For the
first time when i hit fullscreen there is no problem and the slide is
displayed.However on PgDown or a click the next slide is not painted.
The code snippet is below.
gdk_draw_drawable(GetDrawable(),pCopyGC,pSrcGraphics->GetDrawable(),
pPosAry->mnSrcX, pPosAry->mnSrcY,
pPosAry->mnDestX, pPosAry->mnDestY,pPosAry->mnSrcWidth,
pPosAry->mnSrcHeight);
This API documentation says that gives errors like 'badmatch' when there is
a mismatch in the source and dest drawables visuals and colormaps. Is there
any way to debug this as in our case we dont have and X Server ,so no way to
see if the bad match error is actually being reported.
Any help will be greatly appreciated. :)
Regards,
Karl
