Creating an OF transparent Application: Any Way???

beginners
#1

Hi all,

so i want to do a transparent app in OF, but to put it on “top” on my desktop, as a “transparent” window that the user will not see, of partially not see. is that possible?

also, another approach would be to capture the screen “below” the application. Is that possible?

best,

miguel.

I haven’t seen a good way to make a transparent opengl window yet. There’s some info about windows / win32 approaches here, most of which involve drawing offscreen:

http://stackoverflow.com/questions/4052940/how-to-make-an-opengl-rendering-context-with-transparent-background

this is some code for doing screen grabbing on osx:

which might be a good place to start.

I havent tried it, but if you’re on mac, you have ofxTransparentWindow http://forum.openframeworks.cc/t/ofxtransparentwindow-osx-only/4811/0
