Hi,
I am writing an application using EMF & GMF.
GMF in its generated code creates an editor that extends
DiagramDocumentEditor. The palette has a tool "Person Details". This tool
lets u create a Node with a Person Name.
I have a tree viewer that displays Strings of Text with UserNames.

My Doubt:

When i drag a particular Tree item (User Name) from the TreeViewer on to
the Editor, a diagram Node (person Details Node) must be created with the
Username in the Name field of that node.

Can anyone help me figure out
1. How to provide Drop support to the editor. Or should I provide Drop
support to the Container.
2. What kind of transfer takes place ? TextTransfer, FileTransfer, etc...
2. When drop is performed what statements should be written that help in
creating new Node. ( I mean what are classes to be called to create the
node)

I am using GMF v 2.0.1 on Eclipse Europa 3.3

Regards
Amit

Amit,

Please don't cross post the same question to multiple groups using
separate notes. If you must cross post, which seems pointless in this
case, use a single posting addressed to all the groups.

Hello amsurana@in.ibm.com,

You can take GMF-generated org.eclipse.gmf.ecore.editor as an example - D&Ds
from domain/diagram model contents in Project Explorer + EMF-generated Ecore
tree editor are supported there.

Hello Shwetha,

You can start with EcoreDiagramEditor.DropTargetListener, see in addition
DragDropEditPolicy installed in each ???EditPart.
