Filling a jit.window(?) with ARGB values

I'm trying fill a plane with one ARGB value which is changing over time. Right now I use a jit.window and the problem is that what I understand to be the alpha value doesn't seem to have any influence.

Also I'm wondering if a jit.window is the best solution for the problem?

This is the patch I came up with:

Thanks for your help. I had to give all gl objects and the window object an argument to get the patch working but now it does.

But this is not exactly what I'm used to get from an Alpha value. Normally it becomes transparent instead of black or is that a misconception on my side?

Can you or anybody explain why this open GL interference is necessary (since it seems such a trivial task)?

yes, but without a background you can't "see" the transparency.

maybe someone more expert can explain this in word better than me :)
