Fixed bug #113: Date: Sat, 16 Apr 2005 08:39:22 +1000 From: "Eric Mangold" Subject: [SDL] Window manager does not show SDL window titles Hello, I have an issue with SDL-using applications and the sawfish window manager. The problem is that SDL windows do not show the window caption. My gnome panel *does* show the window name, but the actual sawfish window frame shows no caption at all. All other non-SDL applications that I use work fine. I tried a couple other window managers, and they *were* able to show the SDL window captions correctly. Though there many be other WMs that can't. I believe the problem is that SDL is using the UTF8_STRING type for the window's WM_NAME and WM_ICON properties. In fact, WM_NAME and WM_ICON are supposed to set to a TEXT type, usually STRING (ISO 8859-1). The property names _NET_WM_NAME and _NET_WM_ICON_NAME should be used to store the UTF8_STRING versions of the window title and icon name. You can see the properties I refer to with a command like this: xprop|grep -e "WM.*NAME" Please note the freedesktop.org standard: http://standards.freedesktop.org/wm-spec/wm-spec-1.3.html#id2506954 This page talks a little bit about the history of these properties. Just search down the page for "WM_NAME". http://www.cl.cam.ac.uk/~mgk25/unicode.html Please let me know if I can be of any assistance in resolving this issue. Thanks, Eric Mangold
