我正在尝试使用 oops 开发 tkinter 应用程序但收到此错误

Question

I have just started to practice Oops concepts.I'm watching simple Oops video and trying too use apply steps to the tkinter problrm. I don't why I'm getting this error.

from tkinter import *
from tkinter import font as tkFont

top = Tk()
top.minsize(width=1280,height=720)
top.maxsize(width=721,height=521)
class Framesone:
    def __init__(self, x1, y1, frame1, text1, x2, y2):
        self.stframe = LabelFrame(top, width=300, height=200, highlightcolor="grey", bd=5)
        self.stframe.place(x=x1, y=y1)
        self.label1 = Label(frame1, text=text1)
        self.label1.config(font=("Times", "25", "bold", "italic"))
        self.label1.place(x=x2, y=y2)
Framesone(100,200,Framesone().stframe,"HI",20,30)
top.mainloop()

OUTPUT

Traceback (most recent call last):
  File "E:/python projects my/Basic Programs/MQC FIt Software.py", line 14, in <module>
    Framesone(100,200,Framesone().stframe,"HI",20,30)
TypeError: __init__() missing 6 required positional arguments: 'x1', 'y1', 'frame1', 'text1', 'x2', and 'y2'

Answer 1

Framesone(100,200,Framesone().stframe,"HI",20,30)

Framesone().stframe calls the __init__ function without arguments. Everytime you call MyClass() the __init__ function for that class gets called.

Answer 2

When you're calling Framesone().stframe the code first calls the __init__() function of Framesone() , but without any arguments. You're using the object's instance variables before you have declared the object itself.

As you've defined the stframe already in your object you could simply replace references to frame1 with self.stframe as in your example these are the same.

class Framesone:
    def __init__(self, x1, y1, text1, x2, y2):
        self.stframe = LabelFrame(top, width=300, height=200, highlightcolor="grey", bd=5)
        self.stframe.place(x=x1, y=y1)
        self.label1 = Label(self.stframe, text=text1)
        self.label1.config(font=("Times", "25", "bold", "italic"))
        self.label1.place(x=x2, y=y2)

Framesone(100, 200, "HI", 20, 30)

If you do want to use this stframe the way you're using it now, you could move the stframe declaration outside of the __init__() function. This would change stframe from being an instance variable to being a static variable. This would allow you to call Framesone.stframe from outside your class without calling its constructor. (Note you're now calling Framesone without the () indicating you're using its static class variable instead of an instance variable.)

class Framesone:
    stframe = LabelFrame(top, width=300, height=200, highlightcolor="grey", bd=5)
    
    def __init__(self, x1, y1, frame1, text1, x2, y2):
        self.stframe.place(x=x1, y=y1)
        self.label1 = Label(self.frame1, text=text1)
        self.label1.config(font=("Times", "25", "bold", "italic"))
        self.label1.place(x=x2, y=y2)

Framesone(100, 200, Framesone.stframe, "HI", 20, 30)

Edit: removed self from class static variable. Changed wording slightly for better explanation of instance vs static variable
