A layout in the spirit of XMonad.Layout.ResizableTile, but with the option to use the mouse to adjust the layout.

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

import XMonad.Layout.MouseResizableTile

Then edit your layoutHook by adding the MouseResizableTile layout. Either in its normal form or the mirrored version. (The mirror layout modifier will not work correctly here because of the use of the mouse.)

myLayout = mouseResizableTile ||| etc..
main = xmonad def { layoutHook = myLayout }

For more detailed instructions on editing the layoutHook see:

XMonad.Doc.Extending

You may also want to add the following key bindings:

, ((modm,               xK_u), sendMessage ShrinkSlave) -- %! Shrink a slave area
, ((modm,               xK_i), sendMessage ExpandSlave) -- %! Expand a slave area

For detailed instruction on editing the key binding see:

XMonad.Doc.Extending.

The following functions are also labels for updating the data (whose representation is otherwise hidden) produced by mouseResizableTile.

Usage:

myLayout = mouseResizableTile{ masterFrac = 0.7,
                               fracIncrement = 0.05,
                               draggerType = BordersDragger }
               |||  etc..
