這是我原本repo裡的main.py

import subprocess
from Xlib.display import Display
from Xlib import X, XK
dpy = Display()
screen = dpy.screen()
root = screen.root
root.grab_key(dpy.keysym_to_keycode(XK.string_to_keysym("z")),X.Mod4Mask|X.Mod2Mask,1,X.GrabModeAsync,X.GrabModeAsync)
root.grab_key(dpy.keysym_to_keycode(XK.string_to_keysym("q")),X.Mod4Mask|X.Mod2Mask,X.ShiftMask,1,X.GrabModeAsync,X.GrabModeAsync)

def call_rofi():
    if ev.type==X.KeyPress:
        #print(f"press key:{ev.detail}")
        if ev.detail==dpy.keysym_to_keycode(XK.string_to_keysym("z")):
            subprocess.Popen(["rofi","-show","drun"])
def kill_window():
    if ev.type==X.KeyPress:
        if ev.detail==dpy.keysym_to_keycode(XK.string_to_keysym("q")):
            window.kill_client()
while True:
    ev=dpy.next_event()
    call_rofi()
    kill_window()
    dpy.flush()

大多都ai生的
所以我想打掉重練 重開一個main.py
這是我忙一天的結果 最後也都ai教我

from Xlib import display,X,XK
dpy=display.Display()
screen=dpy.screen()
root=screen.root
#註冊事件
screen.root.grab_key(dpy.keysym_to_keycode(XK.string_to_keysym("q")),X.Mod4Mask,1,X.GrabModeAsync, X.GrabModeAsync)
#cursor=root.create_font_cursor(0) <--滑鼠顯示不出來
#cursor=dpy.create_resource_object("cursor")
#root.define_cursor(cursor)
while True:
    event=dpy.next_event()
    if event.type==X.KeyPress:
        if event.detail==dpy.keysym_to_keycode(XK.string_to_keysym("q")):
            X.kill_client(dpy)
    dpy.flush()

其實看整體架構很像GUI的事件循環 像是QT,Tkinter

因為python-xlib的文檔不完整，內容很少
像是我看tinywm裡面有screen().root但python-xlib文檔裡面沒有寫，所以一路從pydoc追到dir()

我就查到dir(scr)而已，我對python底層不熟，scr._data.keys()是ai跟我講的
help(Display.screen)裡面只有:

Help on function screen in module Xlib.display:

screen(self, sno=None)

而uv run python -m pydoc Xlib.display.Display.screen裡面:

Help on function screen in Xlib.display.Display:

Xlib.display.Display.screen = screen(self, sno=None)

看完上面的記錄就說明了Xlib為何複雜，不僅是X11本身協議極其繁瑣，python的綁定文檔不周全，真要查就只能去看複雜難懂的Xlib C API 我就是不想寫C才用python阿 都用py幹嘛還看C文檔
文檔不全這個問題我特別去註冊stackoverflow問（對我以前都沒有在用SO），目前問題還在審核，出來了我再更新文章
我目前的感想是xlib仿佛就像是一個黑盒子 網路上沒什麼教學 那些大佬又不知道在沒有ai和文檔的情況下知道那些函式 好像他們會通靈一樣
