ContainerShape without model representation [message #1829397]

I am looking to create a Multi-Text rectangle that can accept other shapes, but addition of these shapes does not update underlying model of the text object - another words the containment is only at UI level, not the model. How can I achieve this behavior? Thank you.

Alex,

not sure if I understood that correctly. The hierarchy of the graphical representation in Graphiti and the hierarchy of the underlying model can be completely independent. You can have add or custom features that add the additional shape as child of the rectangle, but add the model object somewhere else. The association between model and graphics is then usually done by just linking the 2 objects.

HTH,
Michael

Got sidetracked on other projects so had to halt work on this.

I am looking to create a box conduit of sort that other objects can be dropped onto and when the conduit is moved, objects inside it move as well. Not a hard thing to do as it's a ShapeContainer. This element will have its own palette object that can be dropped onto a diagram, but it will not have a model associated with it, so what interface do I implement for this since ICreate expects model object to be returned?

Alex,

it expects an object to be returned, this does not necessarily need to be a model object. You could e.g. return the (root) pictogram element or I think even null should work.
