感谢支持祝你天天开心

代码如下:

##import libraries
from Tkinter import *
from winsound import *
import os
import ttk

##Initialize
root = Tk()
root.geometry('{}x{}'.format(938, 600))
canvas = Canvas(root, width = 938, height = 505, bg = 'white')
canvas.pack()
label = ttk.Label(root, text ="Hello my name is Scorp welcome to this drums 
app")
label.pack()
label.config(foreground ='black')
label.config(font = ('arial',15, 'bold'))
##PhotoImage(file ="g1.gif")
logo =PhotoImage(file ="drums1.gif")
imageFinal = canvas.create_image(480, 260, image = logo)


##logo =PhotoImage(file ="drums.gif")
##imageFinal = canvas.create_image(530, 80, image = logo)


def move():
    canvas.move(imageFinal, 10, 10 )
    canvas.move(label, 10, 10) 
    canvas.update()

def play1():
    os.system('hi_hat.wav')

##define buttons
button = Button(text = 'move', height = 2, width = 4, command = move)
button.place(x=556, y=550)
button1 = Button(text = 'Hi-Hat', height = 2, width = 10, command = play1)
button1.place(x=20, y=240)
root.mainloop()

推荐答案

您可以将键盘按键与 GUI 按钮功能绑定，这样无论您何时按下选定的键盘按键，该功能都会访问.

You can bind your keyboard keys with your GUI button functions so whenever you you press the selected keyboard key the function will access.

首先你必须创建你的按钮:

First you have to create your button:

btn = Button(text = 'move', height = 2, width = 4, command = move)button.place(x=556, y=550)

现在用一个键绑定它(例如 shift+z):

Now to bind it with a key(for example shift+z):

btn.bind("", move)

现在定义函数:

def move(event=' '):canvas.move(imageFinal, 10, 10 )canvas.move(标签, 10, 10)canvas.update()

您必须为您使用键绑定的函数提供一个事件"参数.我已将 event 的默认值设置为空字符串，因此每当您使用鼠标按下屏幕上的按钮时，它都不会出现错误.

You have to give a 'event' argument to your function which you are binding with a key. I have set the default value of event to a empty string so whenever you press the button on screen using mouse it wont give you an error.
