为什么我的CustomTkinter创建了一个空白窗口，而我已经创建了一个窗口？

Why is my CustomTkinter creating a blank window in addition to the one I created?

问题

我试图在第87行创建一个新窗口。它创建了一个窗口，但也创建了一个白色的窗口，尽管我只创建了一个窗口。

  1. import customtkinter as ctk
  2. import tkinter as tk
  3. import tkinter.font as font
  5. passwordNum = 0
  6. visible = False
  7. textentry = None
  8. titleentry = None
  9. mainWindowVar = None
  11. ctk.set_default_color_theme("green")
  12. loginWindow = ctk.CTk()
  13. loginWindow.geometry("500x500")
  14. button_font = font.Font(size=50) 
  16. # 1.Name, 2.Password, 3. Perms
  17. loginData = {"1": ["1", ["post"]]}
  19. # ...
  21. def Create_Post(master, windowHeight, windowWidth):
  22.     # ...
  24. def Toggle_password_visibility():
  25.     # ...
  27. def Button_handler():
  28.     # ...
  30. def Post_Button(master, windowHeight, windowWidth):
  31.     # ...
  33. def new_post():
  34.     # ...
  36. def Create_main_window():
  37.     # ...
  39. # ...
  41. loginWindow.mainloop()

这是我使用的代码。我尝试创建一个新窗口，但它创建了两个窗口。一个是“正常”的窗口，另一个是只有名称为“tk”的白色窗口。我尝试删除这些行，但是空白窗口就不会创建了。你们有没有人遇到过这个问题？我还尝试将其注释掉并运行，但也不起作用，我不明白是为什么:/

Since you want loginWindow to serve as your application's main window, but want to hide it while post_window is being shown, you should update Button_handler as follows:

  1. def Button_handler():
  2.     uName = uNameEntry.get()
  3.     uPassword = uPasswordEntry.get()
  4.     for name in loginData:
  5.         if name == uName:
  6.             if uPassword == loginData.get(uName)[passwordNum]:
  7.                 invalidLogin.place_forget()
  8.                 # use 'withdraw' to minimize the window w/o destroying it and quitting the app
  9.                 loginWindow.withdraw()
  10.                 # don't call 'Create_main_window()' here
  11.                 # return  # you also don't need this
  12.     invalidLogin.place(relx=0.5, rely=0.35, anchor=tk.N)

Then you should delete the Create_main_window function altogether.

You can use loginWindow.deiconify() to restore the main window when you need it again.
