Try to add your element's class to Project -> Properties -> Object Mapping
Tried Object mapping and does not work..
The child elements on a panel may not be separate elements themselves at all. Certain list box controls and tree controls actually have methods, properties, etc., that access those "child" elements.
Can you post a screenshot of the object browser advanced property list of one of the panels you're trying to get access to?
Attached the snapshot. A tab portion is highlighted by yellow color. Test Complete identifies that area as single object and unable to get any of its properties [ few labels, text fields, progress bar elements etc]
