diva.canvas.interactor.SelectionInteractor
A SelectionInteractor is attached to an object that can be put into and out of a selection. Associated with each such role is a selection model, which is the selection that figures are added to or removed from. When a mouse pressed event has occurred, all figures associated with the same SelectionModel will be unselected before the new one is selected. So, to make sure only one figure is selected at a time, do this: SelectionModel m = new SelectionModel(); SelectionInteractor s1 = new SelectionInteractor(m); SelectionInteractor s2 = new SelectionInteractor(m);
When an item is selected, events are then forwarded to other interactors. If, however, the clicked-on figure has just been removed from the figure, do not forward events. @version $Id: SelectionInteractor.java,v 1.16 2005/12/14 04:14:37 cxh Exp $ @author John Reekie
