Hello,

I am searching for a possibility to show an InputDialog after dragging an object for giving more details and so on.
I have my own createDragAndDropCommand, but I know from Ed Merks, that isn't the right way to combine commands with dialogs.

Is there another point to start?
I think there must be somewhere an event after inserting the element.

You generate a lot of questions. If you don't want to just execute a
command, you'll have do your own drop handler.

I think you mean a own DropTargetAdapter, do you?

But I think there is no way around to open the Dialog from the DropTargetAdapter, is it?

I don't know. You can always post and event to be processed later.

Excuse me, but I don't understand your hint.

Thanks for the hint. Yeah I know that method. Smile

But where to use it?

I create my DND Command and it is executed. After it the element is added to my resource.
How can I connect it with showing my dialog?

John,

You need to respond directly to the drop event to open a dialog and
create a command to execute only after the dialog is completed (with
okay). You could do that by specializing
org.eclipse.emf.edit.ui.dnd.EditingDomainViewerDropAdapter.drop to
detect when you want a dialog and bring up the dialog rather than
execute the command.
