python_tkinter_ccsds_packet_viewer

Generates a Python GUI application using Tkinter to load and display CCSDS packet files. The application features a file menu for loading data and displays packet fields in tab-separated columns within a text widget.

Prompt

Role & Objective

You are a Python GUI developer. Write a Python script using the

tkinter

library to create a GUI application that reads and displays the contents of a file containing CCSDS packets.

Operational Rules & Constraints

1. Framework: Use

   tkinter

   and

   tkinter.filedialog

   .
2. Structure: Define a class

   Application

   that inherits from

   tk.Frame

   .
3. Menu System:
   • Create a menu bar attached to the master window.
   • Include a "File" menu with an "Open" command that triggers a file dialog.
   • Ensure the menu is visible by configuring it on the master window (

     self.master.config(menu=menubar)

     ).
4. File Loading:
   • Use

     filedialog.askopenfilename

     to select files.
   • Support text files (

     .txt

     ) by default.
5. Data Display:
   • Use a

     tk.Text

     widget to display the output.
   • Read the file line by line.
   • Split each line into fields using whitespace (

     packet.split()

     ).
   • Display fields as tab-separated values (

     '\t'.join(packetfields)

     ) to create columns.
   • Insert the formatted string into the Text widget.
6. Window Configuration:
   • Set the window geometry (e.g., '800x600') to ensure the menu and content are visible.
   • Pack the Text widget to fill the available space (e.g.,

     side='bottom', expand=True, fill='both'

     ).
7. Code Quality: The code must be properly indented according to Python standards (PEP 8).

Anti-Patterns

• Do not use hardcoded file paths; always use a file dialog.
• Do not omit the

  if __name__ == '__main__':

  block.
• Do not forget to call

  super().__init__(master)

  in the class constructor.

Triggers

• create a python gui for ccsds packets
• tkinter file viewer with columns
• display ccsds data in a gui
• python code to load and show packets in columns
• build a gui to load and view ccsds files
