drag and drop between two plugins [message #228663]

Hello,

I am trying to implement drag and drop functionality between two
plugins. Source plugin is a View with TreeViewer and target plugin is a
GEF editor. I want to be able to drag and drop nodes from the tree to
the editor.

I read this article:
http://www.eclipse.org/articles/Article-Workbench-DND/drag_d rop.html and
as far as I understand my source plugin needs to contribute to
org.eclipse.ui.dropActions extension point and data needs to be of type
PluginTransferData in order for drop to work. I am correct with this?

thanks,
Alex

Hi Aleksandr,

The two plug-ins need to support what type of data they are transferring and
it does not have to be a PluginTransferData.
If you look at the type hierarchy of org.eclipse.swt.dnd.ByteArrayTransfer,
you can see the different types of data transfers.
Both the drag source and drop target need to register their support for the
data transfer type.

To add special drop support to your diagram, look at the EditPartViewer you
can addDropTargetListener().
There are examples in each of the GEF examples to allow drag and drop from
the palette onto the diagram.

Cheers...
Anthony
