python - 如何使用pynput收听带有修饰键组合的字母键？

问题描述

我正在尝试使用 python 自动化一些东西。我使用 pynput 来监听组合键。我正在尝试听 ctrl+shift+alt 的组合。我对修饰键没有问题，但只有字母键。我查看了 python 文档页面并尝试了以下操作：

from pynput import keyboard
from subprocess import Popen, PIPE
from evdev import uinput, ecodes as e
import os

# The key combination to check
COMBINATION = {keyboard.Key.shift, keyboard.Key.ctrl, keyboard.Key.alt, keyboard.KeyCode.from_char('k')}

# The currently active modifiers
current = set()

def on_press(key):
    if key in COMBINATION:
        current.add(key)
        if all(k in current for k in COMBINATION):
            print("x")
    if key == keyboard.Key.esc:
        listener.stop()

def on_release(key):
    try:
        current.remove(key)
    except KeyError:
        pass

with keyboard.Listener(on_press=on_press, on_release=on_release) as listener:
        listener.join()

从终端运行 python 文件后，脚本无法检测到我的组合键。

解决方案

从文档中，您可以使用此方法。https://pynput.readthedocs.io/en/latest/keyboard.html

from pynput import keyboard

def on_activate():
    print('Global hotkey activated!')

def for_canonical(f):
    return lambda k: f(l.canonical(k))

hotkey = keyboard.HotKey(
    keyboard.HotKey.parse('<ctrl>+<alt>+h'),
    on_activate)
with keyboard.Listener(
        on_press=for_canonical(hotkey.press),
        on_release=for_canonical(hotkey.release)) as l:
    l.join()
