python - 条目小部件中的清除文本不起作用

Question

我正在尝试从条目小部件中删除文本，但它不起作用......

请问我该如何解决？我分开了框架：

frame0 --> 标签和条目

frame1 --> 按钮

它对此有什么影响？在此先感谢，eliran。

import tkinter
import tkinter.ttk


def custom_link():
    
    window4 = tkinter.Toplevel()

    window4.geometry("650x100")   

    frame0 = tkinter.ttk.Frame(window4)
    frame0.grid(row=0, column=0)

    frame1 = tkinter.ttk.Frame(window4)
    frame1.grid(row=1, column=0)

    link_text_label =  tkinter.ttk.Label(frame0, text="Enter link: ")
    link_text_label.grid(row=0, column=0, sticky='w',padx=5)

    link_entry = tkinter.Entry(frame0, width=60, foreground="blue", font=("ariel",11))                 
    link_entry.grid(row=0, column=1, sticky='w', padx=1, pady=3 )

    save_link = tkinter.ttk.Button(frame1, text="Save", command=None)                                      
    save_link.grid(row=0, column=0, sticky='w', padx=5)

    clear_text_btn = tkinter.ttk.Button(frame1, text="Clear", command= link_entry.delete(0, 'end') )        
    clear_text_btn.grid(row=0, column=1, sticky='w', padx=5)


window = tkinter.Tk()

window.geometry("150x100")   

frame = tkinter.ttk.Frame(window)

frame.grid(row=0, column=0)

Btn = tkinter.ttk.Button(window, text="button", command = custom_link)

Btn.grid(row=0, column=0)


window.mainloop()
