Gnome绑定器未正确绑定到XF86AudioPlay

Question

我已经成功地获得了一个Python程序来监听Control + Alt + P和Control + Alt + O即使窗口没有焦点。

但是即使成功绑定（如果拼写正确），我似乎也无法捕获<FX86Audio...>事件。

这是一个有效的代码段：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
##!/usr/bin/python3.5       <- Test this every now and then for compatability

# Reqquires:
# sudo apt-get install libkeybinder-3.0-0 gir1.2-keybinder

import gi
# Python 2
gi.require_version('Gtk', '3.0')
gi.require_version('Gdk', '3.0')
gi.require_version('Keybinder', '3.0')
# Python 3
#gi.require_versions({"Gtk": "3.0", "Gdk": "3.0", "Keybinder": "3.0"})
from gi.repository import Gtk, Gdk, Keybinder, Pango

class A:
    def __init__(self):

        # Basic setup of a window with a label
        self.win = Gtk.Window()
        self.lab = Gtk.Label(label="Hello World!")
        self.lab.modify_font(Pango.FontDescription("sans 36"))

        self.win.add(self.lab)
        self.win.connect("destroy", Gtk.main_quit)
        self.win.show_all()

        self.count = 0

        key = Keybinder  # The module to bind keys
        # key.bind(KEYCOMBINATION, FUNC, ARG)
        key.bind("<control><alt>p", self.say, "Hello")
        key.bind("<control><alt>o", self.say, "World!")
        key.bind("<XF86AudioPlay>", self.say, "World :)")
        key.bind("<XF86AudioPause>", self.say, "World :(")
        key.bind("<AudioPlay>", self.say, "World :/")

        key.init()  # Call the mainloop something like Gtk.main()

    def say(self, key, msg):
        self.count += 1
        print(msg)
        # Python 2
        text="Pressed "+ key + " " + str(self.count) + " times"
        self.lab.set_label(text)
        # Python 3
        # self.lab.set_label(f"Pressed {key} {self.count} times")


A()  # Call the object
if not Keybinder.bind("<control><alt>p", A.say, "Bad News 1"):
    print "Keybinder.bind() failed 1."
if not Keybinder.bind("<XF86AudioPlay>", A.say, "Bad News 2"):
    print "Keybinder.bind() failed 2."
Gtk.main()  # Call the main loop

如前所述，这些键绑定是可接受的，但不起作用：

    key.bind("<XF86AudioPlay>", self.say, "World :)")
    key.bind("<XF86AudioPause>", self.say, "World :(")
    key.bind("<AudioPlay>", self.say, "World :/")

键盘可用于暂停和弹奏rhythembox。

认为Unity妨碍了我将<XF86AudioPlay>键盘快捷键重新映射到另一个序列，但无济于事。

[在其他网站上，它讨论的是gsettings，对于具有Unity接口的Ubuntu 16.04，我的似乎还可以：]

这里是xev输出：

    keys:  13  0   0   0   0   0   0   0   0   0   0   0   0   0   0   0

添加init和更改顺序不会使XF86AudioPlay起作用，但另一方面却没有破坏Control

+ Alt + P和Control + Alt + O继续起作用。

这是我添加/更改的顺序：

    Keybinder.init()
    key = Keybinder  # The module to bind keys
    key.init()  # Call the mainloop something like Gtk.main()

添加：

if not Keybinder.bind("<control><alt>p", A.say, "Bad News 1"):
    print "Keybinder.bind() failed 1."
if not Keybinder.bind("<XF86AudioPlay>", A.say, "Bad News 2"):
    print "Keybinder.bind() failed 2."
第一个键盘绑定程序成功，但是第二个键盘打印到终端：

Keybinder.bind() failed 2.

即使窗口没有焦点，我也已经成功地获得了一个Python程序来监听Control + Alt + P和Control + Alt + O。但是我似乎无法捕获事件...
