Using the Widget Scope, you often find objects whose long-term behavior would be interesting to observe. These objects can be added to the Object Visualizer display directly from the Widget Scope. Simply select the objects of interest, and click the Visualize button. If the Object Visualizer is not already open, it will be opened. Then the objects of interest will appear.
For example, you could:
An EtClassesBrowser object will appear in the Object Visualizer display.
A large amount of activity is apparent in the visualizer display.
A black outline appears around it to indicate that it is selected.
Now you can see which methods do a lot of work as the class hierarchy is expanded and contracted in the hierarchy browser pane.
To observe more of the activity that occurs during expanding and contracting, you could select lines in the Widget Scope scrolled window, and click the Snoop button. This would open a Snooper (see page "The Snooper") which you could use to find more of the related objects. Then from the Snooper you could select objects and press the Snooper Visualize button to view the newly discovered objects.
