Thematic Query Widget - Point Data

Can the Thematic Query Widget be used to query point data?

I am able to use the it for querying polygon data ok, but clicking the point data I have loaded into the widget does not produce a query results "pop-up".

Also, can the "hand" tool be easily changed to a "pointer"?

Yes point data is not supported in ThematicQuery widget Sample.
How ever support for point could be added by
1. Setting appropriate symbol on the Featurelayer (used for displaying query results)based on geometry type of the Layer being queried on.
and
2. Creating a Extent around the mapClick point for querying point data.

Thanks for the response Mehul,

Can you elaborate on how I would go about configuring the .xml (config and/or widget) to add support for querying point data using the Thematic Query Widget?

The Point data Query is not support is out of the box. This will require source code changes
