After some discussion on IRC, I've added a new debugging utility to kdesdk, 
namely KSpy. This is a tiny library which can be used to graphically display 
the QObjects in use by an app. In addition to the object tree, you can also 
view the properties, signals and slots of any QObject. Basically it provides 
much the same info as QObject::dumpObjectTree() and 
QObject::dumpObjectInfo(), but in a much more convenient form. KSpy has 
minimal overhead for the application, because the kspy library is loaded 
dynamically using KLibLoader.

To use it from your code, build and install kdesdk/kspy then #include 
<kspy.h>, finally call KSpy::invoke() when you want to run the probe. The app 
keeps running, so you can see how the state of an object changes over time 
too.

There's a quick screenshot of KSpy at the link below, but it's not really 
much too look at.
