tkinter class继承有三种方式。

提醒注意这几种继承的运行方式

一、继承 object

1.铺tk.Frame给parent：

说明：

• self.rootframe = tk.Frame(parent)
• tk.Label(self.rootframe)

import tkinter as tk

class MyApp(object):

    def __init__(self, parent):

        self.rootframe = tk.Frame(parent)

        self.rootframe.pack()

        self.setupUI()

    def setupUI(self):

        tk.Label(self.rootframe, text='标签').pack()

if __name__ == '__main__':

    root = tk.Tk()

    MyApp(root) # 注意这句

    root.mainloop()

2.直接使用root

说明：

• self.root = parent
• tk.Label(self.root)

import tkinter as tk

class MyApp(object):

    def __init__(self, parent, **kwargs):

        self.root = parent

        self.root.config(**kwargs)

        self.setupUI()

    def setupUI(self):

        tk.Label(self.root, text = '标签').pack()

if __name__ == '__main__':

    root = tk.Tk()

    app = test(root)

    root.mainloop()

二、继承 tk.Tk

import tkinter as tk

class MyApp(tk.Tk):

    def __init__(self):

        super().__init__()

        self.setupUI()

    def setupUI(self):

        tk.Label(self, text='标签').pack()

if __name__ == '__main__':

    MyApp().mainloop()

三、继承 tk.Frame

分两种情况

1.有parent

import tkinter as tk

class MyApp(tk.Frame):

    def __init__(self, parent=None):

        super().__init__(parent)

        self.pack()

        self.setupUI()

    def setupUI(self):

        tk.Label(self, text='标签').pack()

if __name__ == '__main__':

    MyApp(tk.Tk()).mainloop()

    #MyApp().mainloop() # 也可以这样

注意： self.pack()

2.没有parent

import tkinter as tk

class MyApp(tk.Frame):

    def __init__(self):

        super().__init__()

        self.pack()

        self.setupUI()

    def setupUI(self):

        tk.Label(self, text='标签').pack()

if __name__ == '__main__':

    MyApp().mainloop()
