Introduction

PySide Demo is an offline-first GUI application built with PySide6 and featuring PostgreSQL synchronization. This project serves as a demonstration of how to create robust desktop applications that can work offline and sync data when an internet connection is available.

Key Features

• PySide6-based graphical user interface

• Add, edit, and view items in a local SQLite database

• Offline-first functionality: work without an internet connection

• Synchronize local data with a remote PostgreSQL database

• Sophisticated conflict resolution mechanism

Purpose

The main purpose of this project is to showcase best practices in developing modern desktop applications using Python and Qt. It addresses common challenges such as:

• Managing offline and online states

• Synchronizing local and remote databases

• Creating responsive and user-friendly interfaces with PySide6

Whether you’re a beginner looking to learn about GUI development or an experienced developer seeking insights into offline-first architectures, this project provides valuable examples and patterns to follow.
