Working on a way to return the text of a button after the button is clicked in tkinter [duplicate]

This question already has answers here: How to pass arguments to a Button command in Tkinter? 开发者_如何学JAVA (18 answers) Closed 7 months ago.

I'm trying to create a list of buttons that are clicked with this lambda function:

button1.config(command=(lambda x: (clicked.append(x)))(button1.cget("text")))

It seems to sort of work but it prints the button text immediately i.e. it doesn't wait for user to click the button.

Any ideas on how to make it responsive to the button click?

class GraphicsInterface:

    def __init__(self):
        self.window = Tk()
        self.window.geometry("720x500")

        clicked=[]
        button1 = Button(self.window, text="Dice 1", width=13)
        button1.place(x=60, y=160)

        button1.config(command=(lambda x: (clicked.append(x)))(button1.cget("text")))

        print(clicked)

Trying to do all this in a lambda is the wrong approach. It's simply too confusing, if not impossible to do what you want. Instead, create a method that does the work, and use lambda only as a way to call that function:

from Tkinter import *
class GraphicsInterface:

    def __init__(self):
        self.window = Tk()
        self.window.geometry("720x500")

        self.clicked=[]
        button1 = Button(self.window, text="Dice 1", width=13)
        button2 = Button(self.window, text="Dice 2", width=13)
        button1.pack()
        button2.pack()

        button1.configure(command=lambda btn=button1: self.OnClick(btn))
        button2.configure(command=lambda btn=button2: self.OnClick(btn))

        self.window.mainloop()

    def OnClick(self, btn):
        text = btn.cget("text")
        self.clicked.append(text)
        print "clicked:", self.clicked

app = GraphicsInterface()

One way would be to bind the button click event to a function which appends the text to your clicked list. For example,

    self.clicked=[]

    self.button1 = Button(self.window, text="Dice 1", width=13)
    self.button1.place(x=60, y=160)
    self.button1.bind("<Button-1>",self.callback)


def callback(self,event):
    self.clicked.append(event.widget.cget("text"))

You could then add other buttons that also call callback, and get their text through the event parameter.
