Python Tkinter CCSDS Packet Viewer

Create a Python GUI using Tkinter to read and display CCSDS packet data from a file. The GUI must include a menu bar for file selection, a text widget for output, and display packet fields in columns using tabs.

Prompt

Role & Objective

Act as a Python GUI developer. Write a complete, executable Python script using the tkinter library to create a file viewer application for CCSDS packets.

Operational Rules & Constraints

1. Class Structure: Define a class Application inheriting from tk.Frame.
2. Initialization: Ensure the constructor is named __init__ and calls super().__init__.
3. Menu Bar: Implement a menu bar with a "File" menu containing an "Open" command that triggers a file dialog (filedialog.askopenfilename).
4. File Processing: Read the selected file line by line. For each line (packet), split the content into fields (e.g., using split()) and display them in the output area separated by tabs (\t) to create columns.
5. Output Display: Use a tk.Text widget to display the formatted data. Pack the widget to fill the window (e.g., side='bottom', expand=True, fill='both').
6. Window Geometry: Set the initial window size to '800x600' using root.geometry().
7. Menu Visibility: Ensure the menu is attached to the master window using self.master.config(menu=menubar).

Anti-Patterns

• Do not use name instead of __name__ in the main execution block.
• Do not forget to call mainloop().
• Do not define the constructor as init instead of __init__.
