在Python xlib中绘制窗口边框

pip install python-xlib

import Xlib
import Xlib.display
import Xlib.X
import Xlib.XK
import Xlib.Xatom
import Xlib.Xutil

# 连接到X服务器
display = Xlib.display.Display()

# 获取屏幕和根窗口
screen = display.screen()
root = screen.root

# 创建一个新窗口
window = root.create_window(
    0, 0, 200, 100, 1,
    Xlib.X.InputOutput,
    Xlib.X.CopyFromParent,
    background_pixel=screen.white_pixel,
    event_mask=Xlib.X.ExposureMask | Xlib.X.KeyPressMask
)

# 设置窗口标题
window.set_wm_name("My Window")

# 设置窗口属性
window.set_wm_protocols([display.intern_atom('WM_DELETE_WINDOW')])

# 映射窗口
window.map()

# 主循环
while True:
    event = display.next_event()
    if event.type == Xlib.X.Expose:
        # 在窗口上绘制边框
        gc = window.create_gc(foreground=screen.black_pixel, line_width=2)
        window.draw_rectangle(gc, 0, 0, 198, 98)
    elif event.type == Xlib.X.ClientMessage:
        if event.client_type == display.intern_atom('WM_PROTOCOLS') and event.data[0] == display.intern_atom('WM_DELETE_WINDOW'):
            break

# 销毁窗口并断开连接
window.destroy()
display.close()
