I'm not the expert here, but yeah, it's a bit complicated because the DrawingArea has no persisitence, and that was the greatest source of confusion for me. So the technique shown in all the demos, is to make a "backing pixmap" on it, draw to the pixamp( which is a drawable), then reload the pixmap on every expose event for the DrawingArea. I'm sure you already know this, but see: http://perlmonks.org?node_id=583578 So now I attach a layered image script with transparency, on a DrawingArea Hope it helps you, and any code improvements welcome. zentara -- I'm not really a human, but I play one on earth. http://zentara.net/Remember_How_Lucky_You_Are.html
