xmonad-contrib-0.7: Third party extensions for xmonadContentsIndex
Support for simple mouse gestures.

mouseGestureH :: (Direction -> X ()) -> X () -> X ()
mouseGesture :: Map [Direction] (Window -> X ()) -> Window -> X ()
mkCollect :: (MonadIO m, MonadIO m') => m (Direction -> m' [Direction], m' [Direction])

You can use this module with the following in your ~/.xmonad/xmonad.hs:

 import XMonad.Actions.MouseGestures
 import qualified XMonad.StackSet as W

then add an appropriate mouse binding:

     , ((modMask x .|. shiftMask, button3), mouseGesture gestures)

where gestures is a Map from gestures to actions on windows, for example:

     gestures = M.fromList
         [ ([], focus)
         , ([U], \w -> focus w >> windows W.swapUp)
         , ([D], \w -> focus w >> windows W.swapDown)
         , ([R, D], \_ -> sendMessage NextLayout)

This is just an example, of course; you can use any mouse button and gesture definitions you want.

For detailed instructions on editing your mouse bindings, see XMonad.Doc.Extending#Editing_mouse_bindings.

data Direction

An enumeration of the four cardinal directions/sides of the screen.

Ideally this would go in its own separate module in Util, but ManageDocks is angling for inclusion into the xmonad core, so keep the dependencies to a minimum.

show/hide Instances
mouseGestureH :: (Direction -> X ()) -> X () -> X ()
mouseGestureH moveHook endHook is a mouse button event handler. It collects mouse movements, calling moveHook for each update; when the button is released, it calls endHook.
mouseGesture :: Map [Direction] (Window -> X ()) -> Window -> X ()
A utility function on top of mouseGestureH. It uses a Map to look up the mouse gesture, then executes the corresponding action (if any).
mkCollect :: (MonadIO m, MonadIO m') => m (Direction -> m' [Direction], m' [Direction])
A callback generator for mouseGestureH. mkCollect returns two callback functions for passing to mouseGestureH. The move hook will collect mouse movements (and return the current gesture as a list); the end hook will return a list of the completed gesture, which you can access with >>=.
