Selects the row under the given mouse point.  This method is useful when the user
triggers a popup mouse action and you would like to have the table select that row if it
is not already selected.  This allows you to guarantee that there is always a selection
when the user triggers a popup menu.

@param event The event that triggered the popup menu
@return true if the row is selected or was already selected.
