本文实例讲述了Python tkinter模块中类继承的三种方式。分享给大家供大家参考,具体如下:
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() |
