如何知道是否在 tkinter 中单击了按钮？

Question

我想在单击按钮时执行任务。我该怎么做呢？我可以使用两个单独的函数来执行任务，但是我在 'hey' 中的 'if' 块之后有一大段代码，我不想再次输入整个代码。我的代码是：

from tkinter import *

root = Tk()

def hey():
    if bt1 is clicked:
        #do something
    if bt2 is clicked:
        #do something

    #some piece of code

bt1 = Button(root, text = 'yes', command = hey)
bt2 = Button(root, text = 'no', command = hey)

bt1.pack()
bt2.pack()

Answer 1

from tkinter import *

root = Tk()

def func():
     #common code for both buttons

def hey(arg):
    if arg == 1:
        print("button 1 used")
        func() #mention arguments if required
    elif arg == 2:
        print("button 2 used")
        func() 


bt1 = Button(root, text = 'yes', command=lambda: hey(1))
bt2 = Button(root, text = 'no', command=lambda: hey(2))
           # you can add more buttons to do the same function,use hey(n)
bt1.pack()
bt2.pack()

Answer 2

根据您分享的内容，您可以使用参数在按钮中传递标志，例如

bt1 = Button(root, text = 'yes', command =lambda: hey(True))
bt2 = Button(root, text = 'no', command =lambda: hey(False))

而在代码中，你可以做到，

def hey(which): # `which` decides which statement to be followed
    if which:
        #do something
    else:
        #do something
