Right now I have a JFrame and I set it to always be on top (I am faking fullscreen as a workaround to a isFullScreenSupported fail)
However, on Gnome 3 / or Gnome Shell (which ever you prefer, they are the same thing) the top panel still shows above the JFrame, this probably has everything to do with the Shell and not Java, but I was wondering if anyone else had come across this bug/glitch/annoyance before and if so, had any solutions?
Thanks in advance.
“We found that the user experience was improved when we removed the ability to configure the panel to allow it to be in any configuration other than always on top. Why would you ever want to not have the top panel below anything else? You are using Gnome3 incorrectly.”
-_____- and THAT kind of attitude is what kills software 
Do you mean both simulated software fullscreen and exclusive fullscreen mode do not work?
Yes, and no. Exclusive fullscreen mode kinda fucks up Gnome Shell if you don’t close it just right, so that is annoying, but I am talking about the ‘simulated software fullscreen’ where you just create a frame, make it fill the window, and undecorate it. If you try to set it to always be on top, the Gnome Shell top panel sometimes still shows above it, and no matter what you do the bottom right hot spot can still be activated, which sucks, but at least the top right deactivates!
I found the if you request focus right before you maximize the frame it will display over the top panel.
