Transparent Background

[Mike]

Hey everyone,

Right now I'm trying to use pyglet to display a stimulus, and the
stimulus is only around the edges of the window. Is there any way to
make the rest of the window transparent?

Thanks,

[Michael Red]

The window? As in, the OpenGL context, everything? To my knowledge, not natively, and definitely no cross-platform way of doing it reliably. You could maybe somehow screenshot what's behind it and blit it to the context, I suppose?

What platform are you working on? As Mike Redhorse says, I doubt there is a cross-platform way, so you'll have to focus on one platform.

I'd guess that you have to be searching for how to display non-rectangular windows on that platform (because this is done by using partially-transparent windows), and figure out how to open a window yourself by that method (i.e. not using pyglet) and then create an opengl context for that window, and pass that opengl context to pyglet, to draw on.
