[英]Is there a reason to pass master to the __init__ in the super call?
如果我想使用tkinter設置一個類來創建一個非常基本的GUI,是否有任何理由將master
傳遞給__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()
與
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訪問主根對象。 您當前的應用程序可能有效,但在更復雜的示例中可能無效。 如果教程推薦該方法,那么我認為最好遵循該方法。
