Check if a record is selected from a dataPointGrid

I have a dataPointGrid and I want to check if a record from it is being selected (mouse clicked on)

enter image description here

Data point grid above. I want to check if a folder (record) is being selected.

Is there a method that does this?

Solution

  • Add ListGrid#addSelectionChangedHandler() on list grid that is called when (row-based) selection changes within this grid. Note this method fires for each record for which selection is modified - so when a user clicks inside a grid this method will typically fire twice (once for the old record being deselected, and once for the new record being selected).

    Look at the ListGrid#setSelectionType() as well that defines a listGrid's clickable-selection behavior (MULTIPLE, SINGLE, SIMPLE or NONE)
