绑定到tkinter中每个键的键绑定 [英] Keybind that binds to every key in tkinter

问题描述

我正在使用Python创建一个交互式游戏，并且我试图以按任意键继续"的说明进行介绍.我在将所有键绑定到单个操作时遇到了一些困难.

I am creating an interactive game with Python, and I am trying to make an introduction with the instruction "Press any key to continue." I am having some difficulty with binding all the keys to a single action.

我尝试绑定到'< Any>'，但显示错误消息.

I have tried binding to '<Any>', but it displays an error message.

from tkinter import *

window = Tk()

root = Canvas(window, width=500, height=500)

def testing():
    print("Hello World!")

root.bind_all('<Any>', testing)

root.pack()
root.mainloop()

如前所述，'< Any>'键盘绑定导致读取错误消息: tkinter.TclError:错误事件类型或键盘符号"Any" .有没有将每个键绑定到操作的简单方法?

As mentioned before, the '<Any>' keybind results in an error message reading: tkinter.TclError: bad event type or keysym "Any". Is there a simple way to bind every key to an action?

推荐答案

我使用< Key> ，它将捕获任何键盘事件并显示"Hello".并且不要忘记在 testing()中指定 event 或 event = None 参数.

I use <Key> it will capture any keyboard event and print "Hello". And don't forget to specify event or event=None parameter in testing() .

from tkinter import *

window = Tk()

root = Canvas(window, width=500, height=500)

def testing(event):
    print("Hello!")

def countdown(count, label):
    label['text'] = count
    if count > -1:
        root.after(1000, countdown, count-1, label)
    elif count == 0:
        label['text'] = 'Time Expired'
    elif count < 0:
        label.destroy()

root.bind_all('<Key>', testing)

root.pack()
root.mainloop()
