@Cedric:
this post would be nice, if i'd want to move my per-pixel transparent frame;)
but first of all i'd need to get it partly transparent. or did i miss something there?

it just tells you how to hide the window frame, so it only answers the first part of " how to hide window frame or set background opacity"

for the second part check out this link http://workshop.evolutionzone.com/2009/09/29/hack-non-standard-windows-in-processing/

I've played around with this example code and the one found on javas website :


The Swing version correctly enables per-pixel translucency of the background.  I can have a solid foreground object like a button, and have the background highly translucent.

I cannot, however, convince Processing to work the same.  While it can be made to have shapes and transparency of the rectangle over the top of a background, I cannot seem to convince it to have a solid foreground object and translucent background.

Anyone with experience with Processing able to shed light on this problem? Is it because PApplet descends from AWT rather than Swing? (just a stab in the dark right now).

I spent little more time on this. It's not due to PApplet extending Frame, because Frame works just fine when you turn off the decorations.  (tested with a vanilla Frame).
I believe PApplet must be doing something in init() that overrides the background alpha.

A little update.

New Java update today on MacOSX. The AWT-related shaped window still isn't working. Hmm. Thought that it would do the trick today. Maybe next time, eh? The transparency looks fine though.
