`X.L.ByWidth` handle `LayoutMessages`

[geekosaur]

Problem Description

@liskin pointed out here that the new ByWidth module needs to handle Hide and ReleaseResources messages.

Steps to Reproduce

Use X.L.ByWidth with a sublayout that uses Decoration, then switch the layout between screens.

Configuration File

module Main (main) where

import XMonad
import XMonad.Layout.ByWidth
import XMonad.Layout.Tabbed

main :: IO ()
main = xmonad def {layoutHook = ifWidth 1920 simpleTabbed (layoutHook def)}

Checklist

• I've read CONTRIBUTING.md

• I tested my configuration

  • With xmonad version: any
  • With xmonad-contrib version: any version with X.L.PerScreen
