Xmonad - 在指定的监视器和工作区上静默生成程序？

Question

How to start a program on specific monitor and specific workspace silently without focusing on it, sort of like you do when you press Mod + Shift + n ? The problem with the following approach

className =? "ProgramClass" --> doShift ( workspaces !! n ),

is that it not only moves the window to the workspace it also opens a workspace, which I would rather avoid. spawnOn essentially does the same.

This is my current config

Too long comment here. I haven't tested the solution:

doShift doesn't change the workspace up to the documentation, the problem is that the new window is directly opened in the new workspace. I think you should define the ManageHook and execute it:

-- neccesary imports
import XMonad.ManageHook
import qualified XMonad.StackSet as W

-- creates a new ManageHook
openSilent :: WorkspaceId -> ManageHook
openSilent tows = do
   fromws <- liftX $ return . W.currentTag . windowset =<< get -- get the current ws tag
   wid    <- ask                                             -- get opened windowId
   doF $ W.view fromws . W.insertUp wid . W.view tows
--       |               |                |- move focus to "to" workspace
--       |               |- insert window
--       |- move focus back to "from" workspace

The hook should be use as regular

className =? "ProgramClass" --> openSilent "workspaceName"

Ok my problem was XMonad.Hooks.EwmhDesktops after removing it from config doShift works without stealing my focus and moves items to a dedicated workspace without activating it.
