Make SDL window transparent

I don't think you can do this directly with SDL, it is the "Simple" library after all. You could of course get the window handle and use Win32, but that would be a total pain and it eliminates the point of using SDL.

One option might be to uses a cross-platform windows API like wxWidgets with SDL(I've seen it done), although I have no idea how SDL would fare with a malformed window.

The SDL part isn't really that important, im using SDL to set up the window to draw openGL. Maybe wxWidgets is worth checking out..

Yes, it's true... i've done some experiments with both. Here's a tutorial for joining wxWidgets and SDL:
wxWidgets+SDL

I'm also not sure if it will work well on the SDL part, but you can try doing some experiments...

Do you have any idea if it's possible make parts of the window transparent in wxWidgets?

I really don't know because i've never tried to do that (and i don't have wx
installed on this machine). However, it seems you can set a shape of a window:
wxtoplevelwindow

But, again, i've never tried to do that so it's just a guess from me. Try making a post about this in the Alternative Game Libraries forum.
