pynput 和 GlobalHotKeys 没有收到任何键盘事件

Question

此代码适用于 Windows 10，但不适用于 Linux。 Linux 似乎根本没有收到任何键盘事件。当使用 Ctrl-C 在 Linux 上中断程序时，这是堆栈跟踪：

  File "/home/andreas/src/magnetfeld-aux/keyboard_events.py", line 22, in <module>
    key = kbd_q.get()
  File "/usr/lib/python3.9/queue.py", line 171, in get
    self.not_empty.wait()
  File "/usr/lib/python3.9/threading.py", line 312, in wait
    waiter.acquire()
KeyboardInterrupt

代码如下：

from pynput import keyboard
from queue import Queue

kbd_q = Queue(maxsize=1)

def on_activate_s(): 
    kbd_q.put("Hotkey s")


listener = keyboard.GlobalHotKeys({
    's': on_activate_s,
})
listener.start()

while True:
    key = kbd_q.get()
    if key:
        print(key)

如何在 Linux 上将此发送到运行？

Answer 1

启动侦听器后缺少的东西是 listener.wait()。这有效：

from pynput import keyboard
from queue import Queue

kbd_q = Queue(maxsize=1)

def on_activate_s(): 
    kbd_q.put("Hotkey s")


listener = keyboard.GlobalHotKeys({
    's': on_activate_s,
})
listener.start()
listener.wait()

while True:
    key = kbd_q.get()
    if key:
        print(key)
