tkinter 类继承的三种方式

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 = parenttk.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()
