Something like > xdotool search --onlyvisible --name dzen\ title windowunmap %@ || xdotool search --name dzen\ title windowmap %@ can toggle the visibility of bar. I want to know if there is anyway for this to be executed automatically when an app goes fullscreen. I am not talking about $mod+f, but when app goes fullscreen on pressing the internal shortcut like F11 or something.

If this is the case this might be a bug.Sun, 30 Aug 2015 13:10:03 +0000https://faq.i3wm.org/question/6529/add-full-screen-hook/?comment=6532#comment-6532Answer by gurkensalat for <p>I use a dzen2 bar as my status bar. when any app goes fullscreen, the bar is still displayed.
