GammaRay is a high-level runtime introspection tool for Qt applications. In this talk we will look at a number of real-world debugging and profiling problems and how the capabilities provided by GammaRay help you with those.

When creating applications we strive to use higher-level frameworks to obtain results quickly and reduce development effort and long-term maintenance cost. This however provides a few challenges during debugging and profiling. With conventional instruction-level tools we have to have a reasonable deep understanding on the implementation of the frameworks we use to interpret the results correctly. Tools with understanding of the frameworks we use mitigate this problem, GammaRay is such a tool for Qt.

After a brief introduction on how to use GammaRay we will look at a number of debugging and profiling examples covering a wide range of Qt features such as signals/slots, Qt Quick, widgets, state machines, model/view or Qt3D, and see how GammaRay can help in addressing these. All examples are based on real-world problems KDAB engineers encountered in their daily work, and aim at giving you an idea on how GammaRay can help with problems you might encounter in your Qt application.
