Hi all,
is there a migration guide for drag and drop? Right now I am
registering a (custom) class FileTransferDropTargetListener that extends
org.eclipse.gef.dnd.AbstractTransferDropTargetListener by calling
getGraphicalViewer().addDropTargetListener(new
FileTransferDropTargetListener(getGraphicalViewer()));
in my GEF editor's initializeGraphicalViewer() method. However,
org.eclipse.gef.dnd.AbstractTransferDropTargetListener implements
org.eclipse.gef.dnd.TransferDropTargetListener, which is deprecated (so
the deprecated version of .addDropTargetListener() is called).
The javadoc tells me to use
org.eclipse.jface.util.TransferDropTargetListener instead. However,
this is a jface class and not a GEF one so it does not know about
requests and commands and all that.
Is there an easy way to migrate my code and what do I have to do?
Thanks and regards, Thomas.

Yes, thanks, Eric, I see it really does, because
org.eclipse.gef.dnd.TransferDropTargetListener extends
org.eclipse.jface.util.TransferDropTargetListener.
So I guess this deprecation is just to get rid of the (empty) interface
org.eclipse.gef.dnd.TransferDropTargetListener? Maybe because during
transition to 3.1 jface got its own (and did not have one before, just a
guess, though)? And so I can safely continue using
org.eclipse.gef.dnd.AbstractTransferDropTargetListener?
