Python 在一个Tkinter类中从另一个Tkinter类编辑/添加Tkinter小部件

假设我有两个tkinter类，它们充当单独的窗口。我如何从另一个tkinter类中的一个类编辑任何给定的小部件。另外，如何在一个tkinter类中从另一个tkinter类中添加小部件

from tkinter import Tk, Label, Button

class MyFirstGUI:
    def __init__(self, master):
        self.master = master
        master.title("A simple GUI")

        self.label = Label(master, text="This is 
        our first GUI!")
        self.label.pack()

        self.greet_button = Button(master, 
        text="Greet", command=self.greet)
        self.greet_button.pack()

        self.close_button = Button(master, 
        text="Close", command=master.quit)
        self.close_button.pack()

    def greet(self):
        print("Greetings!")

root = Tk()
my_gui = MyFirstGUI(root)
root.mainloop()

from tkinter import Tk, Label, Button

class MyFirstGUI2:
    def __init__(self, master):
        self.master = master
        master.title("A simple GUI")

        self.label = Label(master, text="This is 
        our first GUI!")
        self.label.pack()

        self.greet_button = Button(master, 
        text="Greet", command=self.greet)
        self.greet_button.pack()

        self.close_button = Button(master, 
        text="Close", command=master.quit)
        self.close_button.pack()

    def greet(self):
        print("Greetings!")

root = Tk()
my_gui = MyFirstGUI2(root)
root.mainloop()

我认为最好为您的两个窗口（或至少其中一个窗口）使用顶级小部件。现在将创建第一个窗口，代码到达root.mainloop（）行时将停止。在关闭第一个窗口之前，不会创建第二个窗口

您可以传入每个类的引用

import tkinter
from tkinter import Tk, Label, Toplevel, Button

class MainWidget:
    def __init__(self, master):
        self.master = master
        self.widgetTwo = None

        self.label = Label(self.master, text='Widget One')
        self.label.pack()

class WidgetTwo(Toplevel):
    def __init__(self, master, mainWidget):
        Toplevel.__init__(self, master)
        self.master = master
        self.mainWidget = mainWidget

        self.labelTwo = Label(self, text='Widget Two')
        self.labelTwo.pack()

        Button(self, text='Change Main Widget Text', command=self.ChangeMainWidgetLabel).pack()

    def ChangeMainWidgetLabel(self):
        self.mainWidget.label.config(text='Widget One text changed')


mw = Tk()

mainWidget = MainWidget(mw)
widgetTwo = WidgetTwo(mw, mainWidget)
mainWidget.widgetTwo = widgetTwo

mw.mainloop()
