Overview of Qt Object Inspector

QtObjectInspector is a tool that examines a running Qt application and displays information about its internals. It provides several views into a running Qt application:

QObject list view
QObject tree view
Signal/slot graph view
Signal/slot list view
Property view
Signal trace

This application in still in an experimental state, so it may not compile on some platforms and it may crash or not work as expected on others. Please do not hesitate to report these problems if encountered.

On Unix platforms, QtObjectInspector relies on the LD_PRELOAD mechanism and can non-intrusively inspect any Qt application linked against Qt 3.3.0 or later. The application may be compiled without debugging symbols.

Windows platforms do not support a mechanism like LD_PRELOAD and an application must be slightly modified to be inspected. The signal trace feature is not currently available under Windows.

QtObjectInspector listens on a well-known TCP/IP port. Inspected applications connect to this port to report their state and inform QtObjectInspector about the signals that occur.
