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.
