Typeable has been automatically derived for every type since GHC 7.10, so remove these obsolete derivations. This also allows us to get rid of the `DeriveDataTypeable` pragma quite naturally.

-- $usage
|
|
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
|
|
--
|
|
-- > import XMonad.Layout.Maximize
|
|
--
|
|
-- Then edit your @layoutHook@ by adding the Maximize layout modifier:
|
|
--
|
|
-- > myLayout = maximize (Tall 1 (3/100) (1/2)) ||| Full ||| etc..)
|
|
-- > main = xmonad def { layoutHook = myLayout }
|
|
--
|
|
-- Or, if you want to control the amount of padding placed around the
|
|
-- maximized window:
|
|
--
|
|
-- > myLayout = maximizeWithPadding 10 (Tall 1 (3/100) (1/2)) ||| Full ||| etc..)
|
|
-- > main = xmonad def { layoutHook = myLayout }
|
|
--
|
|
-- For more detailed instructions on editing the layoutHook see:
|
|
--
|
|
-- "XMonad.Doc.Extending#Editing_the_layout_hook"
|
|
--
|
|
-- In the key-bindings, do something like:
|
|
--
|
|
-- > , ((modm, xK_backslash), withFocused (sendMessage . maximizeRestore))
|
|
-- > ...
|
