|
|
-- You can use this module by importing it into your
|
|
-- @xmonad.hs@ file:
|
|
--
|
|
-- > import XMonad.Layout.ResizeScreen
|
|
--
|
|
-- and modifying your layoutHook as follows (for example):
|
|
--
|
|
-- > layoutHook = resizeHorizontal 40 Full
|
|

|
|
-- For more detailed instructions on editing the layoutHook see
