XMonad.Layout.MessageControl

Contents

Description

Provides message "escaping" and filtering facilities which help control complex nested layouts.

Synopsis

Usage

You can use this module by importing it into your ~/.xmonad/xmonad.hs file:

import XMonad.Layout.MessageEscape

Then, if you use a modified layout where the modifier would intercept a message, but you'd want to be able to send it to the inner layout only, add the unEscape modifier to the inner layout like so:

import XMonad.Layout.Master (mastered)
import XMonad.Layout.Tabbed (simpleTabbed)

myLayout = Tall ||| unEscape (mastered 0.01 0.5 $ Full ||| simpleTabbed)

you can now send a message to the inner layout with sendMessage $ escape message, e.g.

-- Change the inner layout
((modm .|. controlMask, xK_space), sendMessage $ escape NextLayout)

If you want unescaped messages to be handled only by the enclosing layout, use the ignore modifier:

myLayout = Tall ||| (ignore NextLayout $ ignore (JumpToLayout "") $
                      unEscape $ mastered 0.01 0.5
                        $ Full ||| simpleTabbed)
