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
