activateRow
Description copied from interface:Activator
Invokes some kind of action on the table row indicated by a given index.Note that the row index supplied is that from the TopcatModel's DataModel, not the Apparent Table, so that remapping the row index according to any current row sorting has already been applied. Possibly that's not the way it should have been done, and it may be desirable to change that in future, but at time of writing that's the way it is.
- Specified by:
activateRow
in interfaceActivator

lrow
