Widgets wont Show Up

问题

我正在尝试制作一个非常简单的应用程序，所以概念是：我有一个主窗口，在窗口内部我想要有两个框架，分别是Options Frame和Content Frame，Options Frame将包含按钮，当点击按钮时，Content Frame中的内容将会改变。我的问题是，def create_options_frame 中的按钮不会显示出来，但我没有收到任何错误消息，请帮助我。

  1. import tkinter as tk
  2. from tkinter import ttk
  3. from tkinter import messagebox
  5. class MainWindow(tk.Tk):
  6.     def __init__(self):
  7.         super().__init__()
  9.         self.geometry('800x300')
  10.         self.title('Catatanku')
  12. class OptionsView(ttk.Frame):
  13.     def __init__(self, master, **kw):
  14.         super().__init__(master, **kw)
  16.         self.grid_rowconfigure(0, weight=1)
  17.         self.grid_columnconfigure(1, weight=1)
  19.         self.create_options_frame().grid(row=0, column=0, sticky='wns')
  20.         self.create_content_frame().grid(row=0, column=1)
  22.     def create_options_frame(self) -> ttk.Frame:
  23.         self.options_frame = ttk.Frame(self)
  24.         btn_buat_catatan = tk.Button(self.options_frame, text='Buat Catatan', font=('Times new roman', 16))
  25.         btn_buat_catatan.pack(fill=tk.BOTH, expand=True)
  27.         btn_buka_catatan = tk.Button(self.options_frame, text='Buka Catatan', font=('Times new roman', 16))
  28.         btn_buka_catatan.pack(fill=tk.BOTH, expand=True)
  30.         return self.options_frame 
  31.         
  33.     def create_content_frame(self) -> ttk.Frame:
  34.         self.content_frame = ttk.Frame(self)

我认为你需要做以下更改：

  • 创建MainWindow的实例，而不是tk.Tk的实例。
  • 在MainWindow内部创建OptionsView的实例。
  1. import tkinter as tk
  2. from tkinter import ttk
  4. class MainWindow(tk.Tk):
  5.     def __init__(self):
  6.         super().__init__()
  8.         self.geometry('800x300')
  9.         self.title('Catatanku')
  11.         # 创建OptionsView的实例
  12.         self.view = OptionsView(self)
  13.         self.view.pack(fill="both", expand=1)
  15. class OptionsView(ttk.Frame):
  16.     def __init__(self, master, **kw):
  17.         super().__init__(master, **kw)
  19.         self.grid_rowconfigure(0, weight=1)
  20.         self.grid_columnconfigure(1, weight=1)
  22.         self.create_options_frame().grid(row=0, column=0, sticky='wns')
  23.         self.create_content_frame().grid(row=0, column=1)
  25.     def create_options_frame(self) -> ttk.Frame:
  26.         self.options_frame = ttk.Frame(self)
  27.         btn_buat_catatan = tk.Button(self.options_frame, text='Buat Catatan', font=('Times new roman', 16))
  28.         btn_buat_catatan.pack(fill=tk.BOTH, expand=True)
  30.         btn_buka_catatan = tk.Button(self.options_frame, text='Buka Catatan', font=('Times new roman', 16))
  31.         btn_buka_catatan.pack(fill=tk.BOTH, expand=True)
  33.         return self.options_frame
  36.     def create_content_frame(self) -> ttk.Frame:
  37.         self.content_frame = ttk.Frame(self)
  38.         return self.content_frame
  41. if __name__=='__main__':
  42.     # 创建MainWindow的实例，而不是tk.Tk的实例
  43.     root = MainWindow()
  44.     root.mainloop()

I think what you need is:

  • create instance of MainWindow instead of tk.Tk
  • create instance of OptionsView inside MainWindow
  1. import tkinter as tk
  2. from tkinter import ttk
  4. class MainWindow(tk.Tk):
  5.     def __init__(self):
  6.         super().__init__()
  8.         self.geometry('800x300')
  9.         self.title('Catatanku')
  11.         # create instance of OptionsView
  12.         self.view = OptionsView(self)
  13.         self.view.pack(fill="both", expand=1)
  15. class OptionsView(ttk.Frame):
  16.     def __init__(self, master, **kw):
  17.         super().__init__(master, **kw)
  19.         self.grid_rowconfigure(0, weight=1)
  20.         self.grid_columnconfigure(1, weight=1)
  22.         self.create_options_frame().grid(row=0, column=0, sticky='wns')
  23.         self.create_content_frame().grid(row=0, column=1)
  25.     def create_options_frame(self) -> ttk.Frame:
  26.         self.options_frame = ttk.Frame(self)
  27.         btn_buat_catatan = tk.Button(self.options_frame, text='Buat Catatan', font=('Times new roman', 16))
  28.         btn_buat_catatan.pack(fill=tk.BOTH, expand=True)
  30.         btn_buka_catatan = tk.Button(self.options_frame, text='Buka Catatan', font=('Times new roman', 16))
  31.         btn_buka_catatan.pack(fill=tk.BOTH, expand=True)
  33.         return self.options_frame
  36.     def create_content_frame(self) -> ttk.Frame:
  37.         self.content_frame = ttk.Frame(self)
  38.         return self.content_frame
  41. if __name__=='__main__':
  42.     # create instance of MainWindow instead of tk.Tk
  43.     root = MainWindow()
  44.     root.mainloop()
