Hi,

I need to populate the values of combo box dynamically which is associated to a property of Node A.Actually the values should be the names of the entities added as compartment to the nodes which are linked to the node A.

So i need the following,
1. To get the list of nodes linked.
2. To get the names of the compartment nodes added to those nodes.

Can anyone please suggest a way to do this?


Thanks,
Jeno

Hi Jeno,

usually the nodes shown inside a compartment are the elements of a collection feature in the underlying model object. Why not asking the model object directly? Call ((View)getModel()).getElement() on or in the appropriate editpart to get it.

If this is not possible you can traverse the hierarchy of the editpart containing the compartment view by calling getChildren() on the editpart. But this is the hierachy of diagram elements.
It depends what you consider as the "name" of a node. In the diagram hierarchy you have to traverse the editpart/figure hierarchy and look for the label (or whatever) which shows the name you are looking for.
If it is possible I recommend the first approach of asking the model object.

HTH.

Regards,
Sebastian

Thanks Sebastian.

I am able to get the list of the nodes as a drop down.

On a different note, i just follow the below link(thread) to populate it as dropdown.
