Catch drop events into WB editor from other views [message #874593]

Hi

I'd like to extend the GWT window builder editor so that i can drop custom items from another eclipse view into the widget designer.

I already tried to reach my goal by contributing to org.eclipse.ui.dropActions. This extensionPoint would exactly do what I need. But the window builder seems no to support PluginTransfer drop actions.

So far I could not find a way to get notifications on WB drop events. Is there an extension point which i couldn't find where it is possible to register for drop events?
In my case i wan't to enable dropping of my custom items from another view and then get notficiations when an item was dropped on a WB widget.

Reguel

Well, there are no API for DND in WindowBuilder.
All component creation operations should go through the palette.
I'm open however to possible contributions, if you want to prepare patch for review.

I've found a way to react on drop events which came from outside the WB editor (see attached source). It's kind of hack, which is enough for now, as we're currently only writing a prototype.
Thanks for your offer to contribute a patch after a review. I will come back to it when we decide to use the Window Builder for the real project. Then we will need a proper way to enable this D'nD mechanism.

I have some dnd hang issue so I'd like to test the event listener; But I am not sure how to activate it; So please give more details concerning steps of how to integrate the class to eclipse plugins folder; Should it be wrapped into jar or it can just be copy/pasted into the plugins folder as it is?
