Hi,

I would need to drag a Part from a partStack and drop it to a tabPane contained into an other part...

Do u think that's possible? What would be the best way to go?

Thx

----------
This was sent already today in the morning but the nntp newsgroup sync has eaten is. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=440142
----------

So your maintain the tabPane inside the part yourself?

The problem in this case is that until I get my Tab DnD into upstream
(target is u40) you can not detect the drop.

But I have another idea for you which is most likely available inside
the nightly (although your use case has not been tested).

You could use MCompositePart and your structure would look like this:

<MCompositePart>
<MPartStack>
<MPart />
<MPart />
<MPart />
</MPartStack>
</MCompositePart>

This way the default DnD handler currently implemented inside our
rendering framework would handle DnD for you.

Please note that to create MCompositePart you need the latest build of
the e4 tools!

I'm sorrt but i'm not an expert with e4...

For declaring my Parts I use PartDescriptor in the e4xmi and to open them i call the createPart method of EPartService.

How do i force it to use a MCompositePart instead of a MPart?

I use the efx ide (nighty build) and the efx target definition (nightly build too)

Thanks a lot for your help

Unfortunately there's no descriptor for MCompositePart!

You'd have to:
a) construct it via code
b) create a Snippet and clone that snippet

The Snippet system works similar to the MPartDescriptor one with the
difference that it is more flexible.
