xmonad 启动时 xmobar 不会出现在窗口堆栈的顶部

Question

我xmobar进入后就遇到了一种奇怪的行为xmonad。当我xmonad（来自.xinitrc，我使用 XDM）时，我xmobar出现但它不在窗口堆栈的顶部或底部。一旦我启动了一个应用程序（例如通过按下终端模拟器Mod + Shift + Return），该应用程序就会使用整个屏幕，就好像它xmobar在底部一样。然后我按下Mod + B并没有任何反应，一旦我Mod + B第二次按下它xmobar就会被提升到顶部，从而减小了应用程序窗口的大小。

在此之后Mod + B的xmonad会话的其余部分正常工作，即它降低/提高（隐藏/显示）xmobar.

我确信我配置错误。我的xmonad.hs样子：

import XMonad
import XMonad.Hooks.SetWMName
import XMonad.Hooks.DynamicLog

main = do
  xmonad =<< statusBar "xmobar" myPP toggleStrutsKey defaultConfig
    { terminal           = "urxvt"
    , focusFollowsMouse  = True
    , clickJustFocuses   = False
    , borderWidth        = 1
    , modMask            = mod4Mask
    , workspaces         = myworkspaces
    , normalBorderColor  = "#dddddd"
    , focusedBorderColor = "#00dd00"
    , manageHook         = mymanager
    , startupHook        = setWMName "LG3D"
    }

myPP = xmobarPP { ppOutput          = putStrLn
                , ppCurrent         = xmobarColor "#336433" "" . wrap "[" "]"
                --, ppHiddenNoWindows = xmobarColor "grey" ""
                , ppTitle           = xmobarColor "darkgreen"  "" . shorten 20
                , ppLayout          = shorten 6
                --, ppVisible         = wrap "(" ")"
                , ppUrgent          = xmobarColor "red" "yellow"
                }

toggleStrutsKey XConfig { XMonad.modMask = modMask } = (modMask, xK_b)

myworkspaces = [ "code"
               , "web"
               , "media"
               , "irc"
               , "random"
               , "mail"
               , "docs"
               , "music"
               , "root"
               ]

mymanager = composeAll
  [ className =? "gimp" --> doFloat
  , className =? "vlc"  --> doFloat
  ]

虽然一开始我的.xmobarrc样子如下：

Config {
  -- appearance
    font =         "xft:Bitstream Vera Sans Mono:size=9:bold:antialias=true"
  , bgColor =      "black"
  , fgColor =      "#646464"
  , position =     Top
  , border =       BottomB
  , borderColor =  "#646464"

  -- layout
  , sepChar =  "%"   -- delineator between plugin names and straight text
  , alignSep = "}{"  -- separator between left-right alignment
  , template = "%battery% | %multicpu% | %coretemp% | %memory% | %dynnetwork% | %StdinReader% }{ %date% || %kbd% "

  -- general behavior
  , lowerOnStart =     False   -- send to bottom of window stack on start
  , hideOnStart =      False   -- start with window unmapped (hidden)
  , allDesktops =      True    -- show on all desktops
  , overrideRedirect = True    -- set the Override Redirect flag (Xlib)
  , pickBroadest =     False   -- choose widest display (multi-monitor)
  , persistent =       True    -- enable/disable hiding (True = disabled)

  -- plugins (i do not use any)

  , commands = [  -- actually several commands are in here
  ]
}

我尝试了以下几种组合：

, lowerOnStart =
, hideOnStart =

（真/真、真/假、假/真和假/假，如图所示）。但是我按Mod + B两次之前的行为没有改变。我相信我xmonad在某种程度上没有配置错误，xmobar但这只是一个猜测。

我的.xinitrc可能有帮助：

#!/bin/sh

if test -d /etc/X11/xinit/xinitrc.d
then
    # /etc/X11/xinit/xinitrc.d is actually empty
    for f in /etc/X11/xinit/xinitrc.d/*
    do
        [ -x "$f" ] && source "$f"
    done
    unset f
fi

# uk keyboard
setxkbmap gb

xrdb .Xresources
xscreensaver -no-splash &

# java behaves badly in non-reparenting window managers (e.g. xmonad)
export _JAVA_AWT_WM_NONREPARENTING=1

# set the background (again, because qiv uses a different buffer)
/usr/bin/feh --bg-scale --no-fehbg -z /usr/share/archlinux/wallpaper/a*.jpg

# pulse audio for alsa
then
    /usr/bin/start-pulseaudio-x11
fi

exec xmonad

两个月后，我想通了。问题是statusBar没有Hooks.manageDocks正确注册事件。一旦xmonad运行一切正常，因为manageDocks能够更新Struts每个窗口事件。但是在开始的那一刻，xmonad使第一个 Windows 全屏显示的事件发生在manageDocks. 这个先开窗的法师就无视了xmobar。

manageDocks有其事件处理程序必须设置为最后一个事件处理程序，因此statusBar不能使用。而是需要通过、、和手动xmonad调用和配置。一个简约的配置是：xmobardynamicLogmanageHooklayoutHookhandleEventHook

main = do
    xmproc <- spawnPipe "xmobar"
    xmonad $ defaultConfig
      { modMask            = mod4Mask
      , manageHook         = manageDocks <+> manageHook defaultConfig
      , layoutHook         = avoidStruts  $ layoutHook defaultConfig
      -- this must be in this order, docksEventHook must be last
      , handleEventHook    = handleEventHook defaultConfig <+> docksEventHook
      , logHook            = dynamicLogWithPP xmobarPP
          { ppOutput          = hPutStrLn xmproc
          , ppTitle           = xmobarColor "darkgreen"  "" . shorten 20
          , ppHiddenNoWindows = xmobarColor "grey" ""
          }
      , startupHook        = setWMName "LG3D"
      } `additionalKeys`
      [ ((mod4Mask, xK_b), sendMessage ToggleStruts) ]

这使得所有事件都被处理docsEventHook并确保布局更改docsEventHook是最后应用的。现在

lowerOnStart = False

（或True）按预期在所有情况中xmobarrc。
