xmonad 布局与 IM 保持相同大小

Question

I have a problem with xmonad and the XMonad.Layout.IM module. I have the following configuration for my layout and no matter to what I change the parameter of "withIM", the window stays always the same size.

Config:

   38 import XMonad.Layout.IM
   39 import XMonad.Layout.Grid
   40 import XMonad.Layout.FixedColumn
   41 import XMonad.Layout.Reflect
   42 import XMonad.Layout.ThreeColumns
   43 import Data.Ratio ((%))

...

   62 sPx = 1
   63
   64 verticalLayout = spacing sPx $ avoidStruts $ reflectHoriz $ Tall 1 0.03 0.5
   65 verticalLayoutLargeScreen = spacing sPx $ avoidStruts $ ThreeCol 1 0.03 0.5
   66 horizontalLayout = spacing sPx $ avoidStruts $ Mirror $ Tall 1 0.03 0.5
   67 webdevLayout = spacing sPx $ avoidStruts $ Tall 1 0.03 0.63
   68 fullscreenLayout = noBorders $ fullscreenFull $ Full
   69
   70 myLayout =
   71     onWorkspace "2:web" (webdevLayout ||| fullscreenLayout) $ reflectHoriz $
   72                     (withIM (1%7) (ClassName "Chat")
   73                     (verticalLayoutLargeScreen ||| Grid ||| Full |||
   74                     verticalLayout ||| horizontalLayout ||| fullscreenLayout))

Update: This is the output of xwininfo with the "(1%7)":

xwininfo: Window id: 0x1400006 "Profanity"

Absolute upper-left X:  3360
Absolute upper-left Y:  0

Corners:  +3360+0  -0+0  -0-30  +3360-30
-geometry 32x74-0+0

And the output stays the same, even after changing the parameter to something else.

Answer 1

I had the same problem and the solution is quite simple. You need to restart your pc (or session) after you changed the rational parameter (eg 1%7, or 3%7, ...) and it works.
