Desktop Apps with Qt Widgets and PySide6

Learn to design UIs visually with Qt Designer and Qt Creator. Load UI files dynamically, compile them to Python code, and manage resources through both manual and automatic workflows.

Master dialog windows in Qt. Create custom dialogs, use dialog button boxes, and leverage built-in dialogs for files, fonts, colors, and user input to build interactive applications.

Transform your applications with professional styling. Learn Qt styles, palettes, style sheets (Qt's CSS), and external styling to create beautiful, branded desktop applications.

Persist application settings between sessions using QSettings. Save user preferences, window positions, and application state for a seamless user experience.

Work with the file system in Qt. Read and write files, navigate directories, and manage file operations with QFile and QDir for robust file handling.

Connect your applications to the internet. Use QNetworkAccessManager for HTTP requests, parse JSON responses, and integrate web APIs into your desktop applications.

Master Qt's event system. Understand event propagation, handle specific events, override QObject event handlers, use event filters, and work with custom events for advanced application control.

Create reusable custom widgets by composing existing widgets or modifying their behavior. Build a water level monitor, datetime widget, and double-clickable button, then promote them in Qt Designer.

Master custom painting in Qt. Learn the coordinate system, draw shapes and paths, use pens and brushes, apply gradients and transforms, and build a complete painting application from scratch.

Implement drag and drop functionality and clipboard operations. Transfer data between widgets, handle dropped images, create custom mime data, and integrate drag/drop into your painting application.

Master Qt's Model/View architecture for displaying and editing data. Work with convenience widgets, standard models, proxy models, custom models with full CRUD operations, custom delegates, and build complex applications like an expense tracker with SQLite.

Master Qt's Graphics View Framework for advanced 2D graphics. Build interactive scenes with items, handle events, implement transforms and selections, create resizable items, house widgets in scenes, implement drag and drop, and build complete projects including a Flappy Bird game and enhanced PainterApp.

Polish your PainterApp into a professional application. Clean up the UI, add pen and brush properties, implement tool cursors, add copy/cut/paste functionality, enable document saving/loading, implement undo/redo, fix smoothness issues, and add application icons.

Make your applications multilingual. Prepare strings for translation, generate translation files, translate using Qt Linguist, create compiled translation files, use QTranslator, load official Qt translations, and save user language preferences.

Learn how to package your PySide6 application for distribution. Prepare your application for deployment across different platforms.

Deploy your PySide6 applications to Windows, Linux, and macOS. Learn manual dependency loading, automated deployment tools, and creating installers with Qt Installer Framework for professional distribution.

You've built a solid foundation in PySide6 and Qt Widgets. Discover what to learn next, which advanced Qt topics to explore, and how to continue growing as a professional Qt/Python developer.
