如何检查是否已使用 Tkinter 按下键? [英] How to check if key has been pressed with Tkinter?

问题描述

所以我正在制作一个程序，它可以检测您是否点击了键盘上的某个键.我知道你可以:

So I'm making a program where it detects if you have clicked a key on your keyboard. I know you can do:

def show(key):
    if key == Key.tab:
       print("Click")


with Listener(on_press=show) as listener:
    listener.join()

除非我想让它检测是否在 Tkinter 窗口未打开的情况下按下了某个键.就像我保持 Tkinter 窗口打开，切换到 Chrome，单击 Tab，我仍然希望程序打印单击"

Except I want it to detect if a key has been pressed if the Tkinter window isn't open. Like if I keep the Tkinter window open, switch to Chrome, click Tab, I still want the program to print "Click"

推荐答案

下载键盘模块:pip3 安装键盘

Download the keyboard module: pip3 install keyboard

import keyboard #Using module keyboard
while True:#making a loop
try: #used try so that if user pressed other than the given key error will not be shown
    if keyboard.is_pressed('a'): #if key 'a' is pressed 
        print('You Pressed A Key!')
        break #finishing the loop
    else:
        pass
except:
    break #if user pressed other than the given key the loop will break

或使用 msvcrt 模块:导入msvcrt

or use msvcrt module: import msvcrt

while True:
if msvcrt.kbhit():
    print('CLİCK')



import keyboard#Keyboard module in Python

rk = keyboard.record(until ='q')#It records all the keys until escape is pressed

keyboard.play(rk, speed_factor = 1)#It replay back the all keys
