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()
