Re-order using drag and drop [message #142271]

Hi,

I'm creating a GMF editor in which I want to be able to re-order model elements
using drag and drop and have not been able to find a sample or posting on
this newsgroup. I'll use the Taipan sample to illustrate the behaviour I'm
looking for.

I'd like to be able to drag and drop the "Small Items" within the "SmallCargo"
compartment and have the underlying model elements re-ordered. So with this
starting point in the model:

<ships name="ship">
<cargo xsi:type="taipan:SmallItems" article="aaa"/>
<cargo xsi:type="taipan:SmallItems" article="bbb"/>
</ships>

I'd like to be able to drag small item "aaa" below small item "bbb" in the
diagram and have both the diagram and the underlying model end up with this
ordering:

<ships name="ship">
<cargo xsi:type="taipan:SmallItems" article="bbb"/>
<cargo xsi:type="taipan:SmallItems" article="aaa"/>
</ships>

So the change is not just a layout change in the diagram.

Thanks,
Keith
