-- Module      :  XMonad.Actions.WindowMenu
-- Description :  Display window management actions in the center of the focused window.

--
-- Maintainer  :  jan.vornberger@informatik.uni-oldenburg.de
-- Stability   :  unstable
-- Portability :  not portable
--
-- Uses "XMonad.Actions.GridSelect" to display a number of actions related to
-- window management in the center of the focused window. Actions include: Closing,
-- maximizing, minimizing and shifting the window to another workspace.
--
-- Note: For maximizing and minimizing to actually work, you will need
-- to integrate "XMonad.Layout.Maximize" and "XMonad.Layout.Minimize" into your
-- setup.  See the documentation of those modules for more information.

-- $usage
--
-- You can use this module with the following in your @xmonad.hs@:
--
-- >    import XMonad.Actions.WindowMenu
--
-- Then add a keybinding, e.g.
--
-- >    , ((modm,               xK_o ), windowMenu)
