我正在尝试创建一个类，将tkinter的标题标签放到一个窗口上，但不知为何它们无法放置。

我已经尝试把.place的调用移出类外，或者调整它的位置，但似乎都不起作用。

我更愿意使用place，因为它是我最熟悉的方法。

该类和窗口位于不同的文件中，且该类已经被导入。

以下是该类的代码

class make_label: 
    def __init__(self, place, text, font_size, x_value, y_value):
        #self.name = name
        self.place = place
        self.text = text 
        self.font_size = font_size
        self.x_value = x_value
        self.y_value = y_value



    def make_label(self): 
       new_label = Label(self.place, 
                     text = self.text, 
                     font=("Century Schoolbook", self.font_size))
       new_label.place( x = self.x_value, y = self.y_value)

以下是窗口的代码

from tkinter import * 

from Classes_File_2503056 import *

main_window = Tk() 
main_window.title("University Student Information") 
main_window.geometry("800x400")


header_label_sl = make_label(main_window,
                             "Student Login", 
                             20, 
                             300, 
                             10)

main_window.mainloop()

解决方案

The issue is that you are creating the make_label object but not calling the make_label method which actually creates and places the label. You need to call header_label_sl.make_label() after creating the header_label_sl object.

from tkinter import * 
from Classes_File_2503056 import *  

main_window = Tk() 
main_window.title("University Student Information") 
main_window.geometry("800x400")  

header_label_sl = make_label(main_window, 
                             "Student Login", 
                             20, 
                             300, 
                             10) 

# Call the method to create and place the label  
header_label_sl.make_label()  

main_window.mainloop()

In your original code, you were initializing the make_label object but never actually telling it to create the label widget and place it on the window. Do this by adding header_label_sl.make_label(): the make_label method creates the Label and uses .place() to put it on the main_window.
