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()
