-- $usage
|
|
-- You can use this module with the following in your @xmonad.hs@:
|
|
--
|
|
-- > import XMonad.Layout.StackTile
|
|
--
|
|
-- Then edit your @layoutHook@ by adding the StackTile layout:
|
|
--
|
|
-- > myLayout = StackTile 1 (3/100) (1/2) ||| etc..
|
|
-- > main = xmonad def { layoutHook = myLayout }
|
|
--
|
|
-- For more detailed instructions on editing the layoutHook see
|
|
-- <https://xmonad.org/TUTORIAL.html#customizing-xmonad the tutorial> and
|
|
-- "XMonad.Doc.Extending#Editing_the_layout_hook".
