Qt GUI Programming with C++

What Will You Learn?

• 1. Qt Framework Fundamentals
• Understand what Qt is and why it’s a leading choice for cross-platform GUI development.
• Set up your development environment with Qt Creator and/or CMake.
• Structure a Qt project with .pro files, .cpp source, .ui design, and .qrc resources.
• 2. GUI Development with Qt Widgets
• Use Qt’s rich widget library to build user interfaces using elements like buttons, labels, input boxes, and containers.
• Manage widget layouts and responsiveness using QHBoxLayout, QVBoxLayout, QGridLayout, etc.
• Design interfaces visually with Qt Designer.
• 3. Event-Driven Programming
• Master the signals and slots mechanism for connecting user actions to responses.
• Define and emit custom signals, connect slots using lambdas or traditional syntax.
• Handle mouse, keyboard, and other input events with custom logic.
• 4. Dialogs and Input Validation
• Use built-in dialogs (file, color, message, font) and create custom dialog windows.
• Validate user input using input masks, validators, and regular expressions.
• 5. Model-View Programming
• Work with data in tables, lists, and trees using Qt’s Model-View-Controller (MVC) architecture.
• Use and extend models like QStandardItemModel and build custom delegates for advanced interaction.
• 6. File and Resource Handling
• Read and write to files using QFile, QTextStream, and QDataStream.
• Use Qt's resource system (.qrc) to bundle images, fonts, and icons into your application.
• 7. Object-Oriented Qt with C++
• Use QObject inheritance, the Q_OBJECT macro, and understand parent-child memory management.
• Build custom reusable widgets and structure your app using object-oriented principles.
• 8. Styling, Theming, and UI Polish
• Style your application using Qt Stylesheets (QSS) and built-in themes.
• Add custom icons, fonts, and localized content.
• Polish the UI for professional look-and-feel and accessibility.
• 9. Concurrency and Background Tasks
• Use QThread, QtConcurrent, and worker objects to offload long-running tasks from the UI.
• Synchronize data using QMutex, QSemaphore, and QWaitCondition.
• 10. Debugging and Testing
• Use tools like qDebug, valgrind, and Qt Creator debugger to troubleshoot problems.
• Write and run unit tests with QTest, measure code coverage, and follow Qt best practices.
• 11. Build Real-World Applications
• Combine widgets, models, signals, threads, and resources to create full applications.
• Build projects like a Notepad, Photo Viewer, Contact Manager, or System Monitor Dashboard.
• By the End of the Course, You Will Be Able To:
• Design and build professional, cross-platform GUI applications using Qt
• Structure medium-to-large Qt projects using modular architecture
• Handle user interaction, dynamic data, background processing, and file I/O gracefully
• Deploy your Qt application across Windows, Linux, and macOS
