Hi,

I wish to drag & drop a IFile [ actually a XML file ] object from project explorer onto Graphiti Editor, which results in creation of a new Node with properties taken from the XML file. I thought of using getDragandDropFeatures in the FeatureProvider class, but it doesn't work.

Please suggest with an example how a file object can be dragged & dropped into Graphiti editor which results in any custom action.

Thanks,
Kunal

Hi Kunal,

if you DnD a IFile into a Graphiti editor, this calls the getAddFeature in your feature provider implementation. There you can handle the case, that the new object is of type IFile and then load its contents as EMF resource to be able to query the model objects. The getDragAndDropFeatures have not to be overridden, this is just used for DnD connection lines.

	@Override
	public IAddFeature getAddFeature(IAddContext context) {
		IAddFeature feature = null;
		if (context.getNewObject() instanceof IFile) {
                   ...
                }
        }



Regards,
Joerg

Looks like I am resurrecting an old discussion...

I am trying to DND an file from a view onto a Graphiti Editor. This works if the view is a Package Explorer - I DND a file and getAddFeature() method gets called, but does not work when I try to DND from a View, class of which extends ResourceNavigator. Is there something that should be done on View side in order for DND to work? An extension point that needs to be implemented?
