Hello everyone,

I have been searching a way to add DropTargetListener(drop support) to the
project explorer tree but i could not find one.

Please help me find this.

Thanks and regards,
Keshav Veerapaneni.

You can add a dropAssistent to a navigatorContent for the project
explorer. You can use the common navigator
org.eclipse.ui.navigator.viewer extension point to hook your
navigatorContent up to the project explorer view.

Look in this file for an example:

/org.eclipse.ui.navigator.resources/plugin.xml

Hello Francis,

Thanks for the reply.
This solves the problem now for me but i also have to register new
Transfer to the viewer which is specific to our Implementation.

There was no element in the extension point by which i can define new
transfer type. Please let me know how can i do this.

Thanks and regards,
Keshav Veerapaneni.

You don't need to register the transfer type with the CNF. You will
subclass COmmonDropAdaptorAssistant which has the mechanism for checking
the transfer type.

If you want to use a new transfer type in your drag, that's an SWT issue.

Hello Francis,

We have a new TransferType which is already included in the dragsource.
Also we have contributed our own tree in the project expoler, now our
usecase is to drop a object from one our trees to the nodes we have
contributed in the project explorer tree.

Right now there are only three transfer types defined for the
projectexplorer tree
LocalSelectionTransfer.getTransfer(),
FileTransfer.getInstance(),
PluginTransfer.getInstance()
Also the CommonDropAdapter#dragEnter method only checks for these three
transfertypes.

Our transertype is not one of these and so the project explorer doesnt
allow me to drop an object on the nodes we have contributed.

So i wanted to ask if there is a way i can register my TransferType with
the explorer tree?

Thanks and regards,
Keshav Veerapaneni.

I'm sorry, when I answered before I did not look into it as much as I
should have.

The answer is (as you suspected) that you can't register your own drop
transfer type.

Please file an enhancement request about this.
