This article provides a comprehensive guide on building a Python desktop application for image conversion using Tkinter and threading. Below is a summary of the key steps involved in creating this app:

Key Steps

1. Setup Project Structure

   • Create directories and files: app, config, db, utils.
   • Initialize SQLite database with necessary tables.

2. Install Required Libraries

   • Install tkinter (built-in), Pillow for image processing, and sqlite3 for database operations.
   • Optionally install messagebox for GUI alerts.

3. Database Initialization

   • Create a function to initialize the SQLite database with tables for history tracking.

4. Tkinter Application Setup

   • Define the main application class (App) inheriting from Tk.
   • Initialize components like buttons, progress bar, and drop target registration for drag-and-drop functionality.

5. Drag & Drop Support

   • Register the root window to accept file drops using drop_target_register and bind it to a function that processes dropped files.
