VMware's Christian Hammond and David Trowbridge have released a new tool called Parasite that can hook into GTK+ applications to facilitate interactive GUI debugging.
Parasite will provide a visual outline of the widget hierarchy and allow you to dynamically modify various widget properties while the program is running.
