Tkinter:如何在按下按钮时显示窗口 [英] Tkinter: how to make window appear when a button is pressed

问题描述

我想用 Tkinter 创建一个窗口.这个窗口应该有一个按钮.按下按钮时，我希望出现第二个窗口(第一个窗口不会消失).

I want to create a window with Tkinter. This window should have a button. When the button is pressed, I want a second window to appear (without the disappearance of the first).

代码，缩短:

from Tkinter import *
from modules.startingKit.highscore import Highscore


class OptionWindow:

    def __init__(self):
        self.master = Tk() 
        self.b4 = Button(self.master, text = "display Highscores", command = self.display()).grid(row=0, sticky = W)
    mainloop()



    def display(self):
        myWin = Toplevel()

好吧，显示了第二个窗口，但在我按下按钮之前.我可以改变这个吗

Well, the second window IS displayed, but before I press the button. Can I change this

推荐答案

command 属性接受一个函数的引用.当您执行 command=self.display() 时，您正在调用该函数并将结果传递给 command 属性.

The command attribute takes a reference to a function. When you do command=self.display(), you are calling the function and passing the result to the command attribute.

解决方法是省略括号:

self.b4 = Button(..., command=self.display, ...)
