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
