[英]Is there a reason to pass master to the __init__ in the super call?
如果我想使用tkinter设置一个类来创建一个非常基本的GUI,是否有任何理由将master
传递给__init__()
?
from tkinter import *
class Application(Frame):
def __init__(self, master):
#The original example passes master to __init__()
super(Application, self).__init__(master)
self.grid()
self.create_widget()
def create_widget(self):
'''put a button "Blank" with no fucntion in the GUI'''
self.bttn = Button(self, text = "Blank")
self.bttn.grid()
root = Tk()
root.title("simple GUI")
root.geometry('200x200')
app = Application(root)
root.mainloop()
与
from tkinter import *
class Application(Frame):
def __init__(self, master):
#Code runs fine with out master being passed
super(Application, self).__init__()
self.grid()
self.create_widget()
def create_widget(self):
'''put a button "Blank" with no fucntion in the GUI'''
self.bttn = Button(self, text = "Blank")
self.bttn.grid()
root = Tk()
root.title("simple GUI")
root.geometry('200x200')
app = Application(root)
root.mainloop()
可能有一些操作需要主窗口访问主根对象。 您当前的应用程序可能有效,但在更复杂的示例中可能无效。 如果教程推荐该方法,那么我认为最好遵循该方法。
