How to differentiate select/deselect by user clicking or by using selectRecord()

[steven2012]

Hi all
I am using Smart GWT version 5.0p-20150412.
Currently, I use addSelectionUpdatedHandler() to catch event after selection/deselection a record in ListGrid.

But, when this method is fired, I can not recognize selection/deselection by user selection or by using selectRecord().
Please help me to solve this problem

Thanks
