About:
GammaRay is a powerful Qt application introspection tool that allows developers to examine and manipulate the internal state of Qt applications at runtime. It provides a GUI to interact with Qt objects, view properties, monitor signals and slots, and analyze performance. The tool is invaluable for debugging complex Qt UI issues and understanding application architecture.

Key Features:

Runtime object inspection and manipulation
Signal and slot monitoring and debugging
Qt Quick scene visualization and debugging
Performance profiling and analysis tools
Plugin-based architecture for extensibility

Use Cases:

Debugging Qt UI issues and widget behavior
Understanding and profiling Qt application performance
Learning how Qt applications are structured internally

Alternatives:

Qt Creator – Qt Creator is an IDE with debugging features, but GammaRay provides deeper Qt-specific introspection capabilities
gdb/lldb – General purpose debuggers that lack Qt-specific object model awareness
