-#+title: Interfacing with window managers
-
-Listed below are ways to interface xmobar with your window manager of
-choice.
-
-* Using the DBus IPC interface with XMonad
-
- Bind the key which should {,un}map xmobar to a dummy value. This is
- necessary for {,un}grabKey in xmonad.
-
- #+begin_src haskell
- ((0, xK_Alt_L), pure ())
- #+end_src
-
- Also, install =avoidStruts= layout modifier from =XMonad.Hooks.ManageDocks=
-
- Finally, install these two event hooks (=handleEventHook= in =XConfig=)
- =myDocksEventHook= is a replacement for =docksEventHook= which reacts on unmap
- events as well (which =docksEventHook= doesn't).
-
- #+begin_src haskell
- import qualified XMonad.Util.ExtensibleState as XS

- } ) =
- io (keysymToKeycode d ks) >>= toggleDocks >> return (All True)

- | ekc == kc && et == keyPress = do
- safeSendSignal ["Reveal 0", "TogglePersistent"]
- XS.put ( DTT etime )
- | ekc == kc && et == keyRelease = do
- gap <- XS.gets ( (-) etime . lastTime )
