the class TableEventHelperFacade method fireEvent.

@Override

    final CyEventHelper eventHelper = getEventHelper();
    // always propagate the actual event
    eventHelper.fireEvent(event);

Example 2 with ColumnDeletedEvent

use of org.cytoscape.model.events.ColumnDeletedEvent in project cytoscape-impl by cytoscape.
