(I don't know the > graphical notions, that's my problem) Yes. They're called layers I think. And I don't think svgalib has a supprt for them, though it would be possible in a separate library. If you don't want to support tansparency you could probably do it by build areas in memory as copying the pixels when you want the result displayed. > I'm thinking of anything like layers in Gimp or another > example: the windows in X11 (when you remove the window you > still sees the background)... Yep. This is what X does. This is what it is for. > Hope you can help me... > > My second problem is, I don't knwo how to set down the mouse > sensivity - like in the SVGAlib example 'spin'...
