如何使用xcbpython在根窗口上为X11窗口管理设置SubstructureRedirect事件掩码

Question

我的代码没有给出任何异常，但我似乎没有接收到像MapRequests或ConfigureNotifys这样的事件：

import xcb
import xcb.xproto as xproto
conn = xcb.connect()
root = conn.get_setup().roots[0].root
eventmask = [xproto.EventMask.SubstructureRedirect, xproto.EventMask.SubstructureNotify]
conn.core.ChangeWindowAttributesChecked(self.root, xproto.CW.EventMask, eventmask)
while True:
    e = conn.wait_for_event()
    print e

我正在Xephyr测试这个。在

我做错什么了吗？如果是的话，我该怎么解决呢？在

编辑： 问题在于参数数目不正确：xproto.CW.EventMask表示您有一个值，而您将两个值作为[xproto.EventMask.SubstructureRedirect, xproto.EventMask.SubstructureNotify]传递，这应该是[xproto.EventMask.SubstructureRedirect|xproto.EventMask.SubstructureNotify]

import xcb
import xcb.xproto as xproto
conn = xcb.connect()
root = conn.get_setup().roots[0].root
conn.core.ChangeWindowAttributesChecked(self.root, xproto.CW.EventMask, [xproto.EventMask.SubstructureRedirect|xproto.EventMask.SubstructureNotify])
while True:
    e = conn.wait_for_event()
    print e
