Version: unspecified (using KDE 4.6.2) OS: Linux Kwin rules do not seem to support matching a window's state(WM_STATE). It would be benefical if kwin rules had the ability to match a "maximized" window, in addition to other window states. ----use case--- I want to remove titlebar in maximized firefox windows, as it is more "stylish", and more importantly, it's space efficient. I can match the firefox windows in a kwin rule but I cannot match the maximized state. A general rule removes the titlebar & borders in smaller/popup window. --------------- I checked the source for possible hidden options but could not find matching the WM_STATE. xprop on a maximized window gives: _NET_WM_STATE(ATOM) = _NET_WM_STATE_MAXIMIZED_VERT, _NET_WM_STATE_MAXIMIZED_HORZ on a normal window, it's empty. _NET_WM_STATE(ATOM) = Reproducible: Always
For your usecase there is the scripting API which would support that. Adding tracking maximized state with the window rules is not trivial and would probably not been added.
@Gokdeniz You're aware that FF has a built-in fullscreen feature that (you want to use? and) also will allow you to end this state from the FF menu or the figured shortcut (where you'd need to know about alt+f3 or have a decoration toggle shortcut with your attempt) If you wish to hide the menubar for /all/ maximized clients, this is possible through an undocumented feature of kwin: kwriteconfig --file kwinrc --group Windows --key BorderlessMaximizedWindows true qdbus org.kde.kwin /KWin reconfigure

While I have not looked into Kwin scripting API yet, filtering windows by window state seemes like a good idea. In compiz, one can enter filters like this any & !(class=Firefox & state=maxvert & role=browser) source: http://www.webupd8.org/2011/03/firefox-4-get-tabs-in-title-bar-like.html
