How to configure the quicklaunch plasmoid (aka widget) so as to fix a problem with missing icons and other issues.
First it seems that the quicklaunch keeps a link to several desktop files – the desktop icons and quicklaunch configuration are pretty opaque really but I do like the idea that kickoff (application menu) items, quicklaunch icons and desktop icons all share a common pool of files that are simply linked elsewhere. This means that searches in the K menu (application menu) will find .desktop files (application launching files) that aren’t actually in the menu.
Anyway, I digress. The files appear to be from
/home/$USER/.local/share/applications/ , where $USER is your user login name. Thus by opening
/home/alicious/.local/share/applications/firefox.desktop and altering the Icon= line directly I was able to update the icon pointed to from the quicklaunch. It didn’t resolve immediately but a logout-login cycle fixed it up for me.
I searched on linuxquestions, ubuntuforums and forums.kde.org and couldn’t find this info so hope it helps.
This is the file as fixed:
Comment[en_US]=Browse the World Wide Web
Comment=Browse the World Wide Web
Exec=firefox -ff-profile %u
Name[en_US]=Firefox Web Browser (3.5)
Name=Firefox Web Browser (3.5)
