覆蓋 KDE 中任意視窗的視窗標題並設置自定義視窗標題

  • February 17, 2021

在這裡使用 KDE，但也可能有適用於其他桌面環境的解決方案。我經常處理很多很多視窗。大多數視窗包含許多選項卡（例如，帶有許多選項卡的 Dolphin 視窗，或 Firefox、Konsole 等）。視窗標題將根據我目前的選項卡而改變（這在大多數情況下很有幫助），但是當使用這麼多視窗時，我想對它們進行一些組織並能夠手動重命名視窗，覆蓋應用程序給出的視窗標題。我可能將一個 Firefox 視窗命名為“研究”，將另一個 Firefox 視窗命名為“文件”，以便能夠輕鬆區分我用來組織和分組不同選項卡的視窗。

理想情況下，我可以點擊視窗標題欄並輕鬆為其指定自定義名稱，但我會選擇一個稍微麻煩一些的解決方案，只要它有效。

我已經嘗試過wmctrl -r :SELECT: -T "Research"，但這只能暫時起作用（當應用程序更改標題時，例如在切換選項卡時，標題會恢復）。

我有這個完全相同的問題。

所以我編寫了一個綁定到熱鍵的 shell 腳本。

當我按下熱鍵時，它會獲取目前活動視窗（具有焦點的視窗）的視窗 ID。

然後它會為您提供一個彈出對話框，您可以在其中輸入您希望該視窗具有的標題。

然後，每次該視窗更改其名稱時，它都會將其更改回您想要的標題。

要使用該腳本，您需要：

  • fish外殼

（我用 fish 而不是 bash 寫的，因為 bash 讓我頭疼）

  • kdialog
  • 將腳本綁定到熱鍵的某種方式

（我使用xbindkeys，因為要讓它工作我所要做的就是添加：

"[PATH TO SCRIPT]/[NAME OF SCRIPT]" Mod4 + t

（即視窗鍵 + t）

到 my /home/o1/.xbindkeysrc）

感謝這個傢伙，他給了我關於魔法 xprop 東西的資訊。

（就像一年前一樣，直到今天我才開始寫劇本。xD）

PS如果有新手找到這個答案並且不知道如何使用它，請問我，我會引導你完成它。^^

編輯：我對其進行了更新，以便您可以在命令行中使用-tfortitle_i_want和-wfor開關來使用它window_id。

這是腳本：

#!/usr/local/bin/fish

# this block is so you can use it from the command line with -t and -w
if test "$argv" != "" -a (math (count $argv)%2 == 0)
   for i in (seq 1 (count $argv))
       if test $argv[$i] = '-t'
           set title_i_want $argv[(math 1 + $i)]
       else if test $argv[$i] = '-w'
           set window_id $argv[(math 1 + $i)]
       end
   end
   if not test $window_id
       echo "YOU DIDN'T ENTER A `window_id` WITH `-w`,
SO MAKE SURE THE WINDOW YOU WANT HAS FOCUS
TWO SECONDS FROM NOW!"
       sleep 2
   end
end

# get the id of the currently focused window
if not test $window_id
   set window_id (xprop -root _NET_ACTIVE_WINDOW | grep -P -o "0x\w+")
end

# get the title to force on that window

if not test $title_i_want
   set title_i_want (kdialog --title "entitled" --inputbox "type the title you want and hit enter.
to stop renaming,
just enter nothing and hit esc")
end

# this bit is needed for a kludge that allows window renaming
set has_renamed_before "FALSE"
set interrupt_message "WAIT WAIT I WANT A TURN BLOO BLOO BLEE BLUH BLOO" # hopefully i never want to actually use that as a title xD
xprop -f _NET_WM_NAME 8u -set _NET_WM_NAME $interrupt_message -id $window_id

# take the output of xprop
# pipe it into a while loop
# everytime it outputs a new line
# stuff it into a variable named "current_title"
xprop -spy _NET_WM_NAME -id $window_id | while read current_title

   # cut off extraneous not-the-title bits of that string
   set current_title (echo $current_title | grep -P -o '(?<=_NET_WM_NAME\(UTF8_STRING\) = ").*(?="\z)')

   # if the current title is the interrupt message
   # AND
   # this script has renamed the window at least once before
   # then we wanna let the new name take over
   if test $current_title = $interrupt_message -a $has_renamed_before = "TRUE"
       exit
   # if title_i_want is an empty string, exit
   else if test $title_i_want = ""
       xprop -f _NET_WM_NAME 8u -set _NET_WM_NAME "WIDNOW WILL START RENAMING ITSELF AS NORMAL" -id $window_id
       exit
   # otherwise just change the title to what i want
   else if test $current_title != $title_i_want
       xprop -f _NET_WM_NAME 8u -set _NET_WM_NAME "$title_i_want" -id $window_id
       set has_renamed_before "TRUE"
   end
end

編輯：我實際上不再使用這個 Fish 腳本了；

我用 Ruby 重寫了它：

                       opt :title_i_want,  "title_i_want",     default: ""
