Hello, I want to paint in some widget, but this will be in front of some background, so the bg should be transparent. At the moment it looks something like this (where it isn't the case): -- drawA <- drawingAreaNew widgetSetSizeRequest drawA 30 30 fixedPut fBox drawA (400,400) imgAt <- imageSurfaceCreateFromPNG "some.png" let drawC = do dw <- widgetGetDrawWindow drawA drawWindowClear dw renderWithDrawable dw $ do translate 9 9 rotate 0.3 translate (-9) (-9) setSourceSurface imgAt 0 0 paint onExpose drawA (const $ drawC>> return True) -- -- best regards H.

ahh, you want to paint against the desktop, then, yes? That requires compositing, and I'm not sure there's a way to do that with Gtk directly. Probably easier with X and OpenGL. Needs more of a Gnome expert than me.
