Description:
Tool for examining the internals of Qt application
GammaRay is a tool for examining the internals of a Qt application and to some extent also manipulate it. GammaRay uses injection methods to hook into an application at runtime and provide access to a wide variety of interesting information. It provides easy ways of navigating through the complex internal structures you find in some Qt frameworks, such as QGraphicsView, model/view, QTextDocument, state machines and more.
