Hi everyone,
I just want to know if i can add drop support to ecore editor. I am trying to something like :
int operations = DND.DROP_COPY | DND.DROP_MOVE;
Transfer transfers[] = new Transfer[] {TextTransfer.getInstance()};
StructuredViewer viewer = (StructuredViewer) eEditor.getViewer();
viewer.addDropSupport(operations, transfers,
new MyDropAdapter(eEditor.getEditingDomain(), viewer));
But in MyDropAdapter constructor when it calls super method like this:
public class MyDropAdapter extends EditingDomainViewerDropAdapter {
.....
public MyDropAdapter(EditingDomain domain, Viewer viewer) {
super(domain, viewer);
}
.....
}
I am get an error : Unhandled event loop exception, Cannot initialize Drop
Also i tried same at debug mode and i realized the program throws an error when it trying to create on org.eclipse.swt.dnd.DropTarget:
public DropTarget(Control control, int style) {
.....
if (control.getData(DND.DROP_TARGET_KEY) != null) {
DND.error(DND.ERROR_CANNOT_INIT_DROP);
}
......
}
Any help would be so grateful.
Thanks,
Anil Ozturk.

Anil,
The generated editor already has support for drag and drop support.

Anil,
Yes, it's possible, but I can't help you debug that.
