I have now determined that the problem I was having with KDevelop's widgets is distinct from the problem with the fonts. I built the releas 3.1.1 from the www.kde.org site, and I still have a problem with the fonts. I'm almost certain this started with my installing KDE 3.1.1 and QT 3.1.2. I have to observe that I'm not directly using either one of these. My QTDIR is /usr/local/qt-3.1.2 which I built myself, and my KDEDIR /opt/kded is symlinked to /opt/kde-3.1.1-release which I built. The problem with the fonts seems to be that the documentation has Helvetica hard-coded into the HTML. Why? Don't ask me, but removing the obnoxious blight allows me to read the document in Konqueror. I'm still uncertain as to what the problem with the fonts is. My guess is, there is some kind of font replacement mapping getting in the way. I've tried removing the /etc/X11/qtrc and rebuilding the fonts cache, to no avail. There is the chance that my problem with kdevelop could be internal to my setup, though I doubt it. I tried pretty hard to remove any references to my own versions of things when trying to isolate the source of the problem. STH
