I'm configuring a Raspberry Pi as a set-top box. I can get Firefox and Chromium to start up in full screen mode. But I want the LXPanel (configured to auto-hide) to respond when the browser is running in full screen mode. However either it does not activate when I move my mouse to the bottom of the screen or it is popping up underneath the browser window (same with both browsers).
Update I've noticed that while running in normal window mode, with the window slightly smaller than full screen, lxpanel expands underneath the browser window.
Note that the panel does not have the usual window decoration so I can't right click. I believe that it should be possible to create an openbox rc file - if only I new the application class.
Apparently the application class (and lots of other X attributes) can be found with xprop
