The short answer is that non-ThreeD borders are just plain X window borders. We don't do anything with them ourselves, we just tell X to put 'em on the windows (it's one of the 59 args to XCreateWindow()). And fiddle with the coloring on focus changes (see SetFocusVisualAttributes()). Differences in screenshot etc are presumably because of that; X put the border there, so it knows the border isn't part of the window, it's just the border. ThreeDBorders came way later (in 3.1), and don't involve X at all. We draw them ourselves (see PaintBorders()) with a buncha lines and rectangle fills etc. Bascially just drawing pixmaps in our window. Which means they're not really "borders" as far as X is concerned, it's just something we draw in our window, like anything else any program draws in its window. And hence all the mess of what borders do to window sizes and positions and whatnot that fall out from that... -- Matthew Fuller (MF4839) | [email protected] Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
