Full-screen Glass Pane. Is it possible?
I'm a Computer Engineering student, so I have minimal experience with programming (200 level C and Java), however, I have a problem I'd like to tackle.
I have read about the Glass Pane overlays that exist in every JFrame. I've also read how to make it visible, and I imagine drawing on it is relatively simple as well.
My question is this:
Is it possible to create a full screen (with a known resolution) Glass Pane over a non-Java game or application?
I imagine if it were possible, it would involve creating a new Java window which was invisible over the screen, then making only the glass pane visible. This would seem problematic, however, since the Java window might have the focus, so one couldn't play the game or use the application while something was drawn on it.
The long story short, of course, is that I want to have a transparent overlay that is visible regardless of what has the focus. If this isn't possible, perhaps someone has an idea of where I should go looking for answers? Can it be done in C? (program would be for Windows) Should I look to DirectDraw or OpenGL or X11?
Thanks in advance, and forgive anything in this post that makes me look terribly inexperienced... which I am.
