Now all seems to work fine, I must to check it for possible bugs but I put
the code below, I hope it helps someone, someday, somewhere,...
public class FigMacmasAssociation extends FigAssociation {
private PropertyChangeListener removeModelElementListener;
public FigMacmasAssociation(){
super();
}
public FigMacmasAssociation(Object edge, Layer lay){
super(edge, lay);
}
public void updateListeners(Object oldOwner, Object newOwner) {
Object obj = oldOwner;
if(obj == null)
obj=newOwner;
if(removeModelElementListener!=null)
Model.getPump
().removeModelEventListener(removeModelElementListener,obj);
super.updateListeners(oldOwner, newOwner);
addRemoveAssociationListener(newOwner);
}
protected void addRemoveAssociationListener(Object owner){
//System.out.println("RAVNOCK metodo removeAssociationListener");
removeModelElementListener=new PropertyChangeListener() {
public void propertyChange(PropertyChangeEvent evt) {
//System.out.println("RAVNOCK metodo disparado");
if (evt instanceof RemoveAssociationEvent) {
// do what you want to do when this event is fired
//System.out.println("RAVNOCK evento disparado");
return;
}
}
};
Model.getPump().addClassModelEventListener(removeModelElementListener,
Model.getMetaTypes().getModelElement(),(String []) null);
}
}
2007/7/12, David Orejuela <[EMAIL PROTECTED]>:
Well, It's really confusing the method name, sorry. And sorry again, I'll
fix the second error: never removing the listener. :(
And to the last question:
When I add to my diagram a new association between my figs, I need that
new attributes are created inside them. So when the association is deleted,
I must delete the associations too. Then, when I create the association, I
listen for the delete, and when it happens I look for the attributes and
delete them, probably with the removeFromDiagramImpl method. (and also
remove the listener?).
I don't know other way to obtain this result, maybe it's wrong , or not?
some help?
Thanks.
