Forcing compartment elements to stay within the compartment boundary. [message #41345]

Hi,

I have a compartment with some elements in it.When I drag these elements
out of the compartment they come out of it due to which the generated
xml changes.
I want to force these elements to stay within the compartment boundary
even if I try to drag it outside the compartment. Within the compartment
I should be able to position it wherever I want.

can anyone help????

Regards

Hi Sayed,

maybe I've encountered a similar problem. But now it is solved.
My problem was that Labels which should be contained in a compartment
doesnt stay in there.
Take a look at the solution in the Thread: "Showing Attribute Labels in
Compartment". Which was startet yesterday.

kind regards,

andreas

Hi Andreas,

I think that the problem I am facing is different from yours.

I have a rectangular figure say NodeA.This contains another node
say NodeB.So the xml that is generated looks like:

< node a name = "NodeA">
<NodeB name = "NodeB" />
</nodeA>
Now when I drag the nodeB and take it outside NodeA the xml generated is

<NodeA name = "NodeA"/>
<NodeB name = "NodeB"/>

I have not specified any TopNode reference for NodeB because I dont want
NodeB outside NodeA. I want to force NodeB to be inside NodeA even if I
try to drag it outside.

Thanks

So, if you are not able to create NodeB on the diagram surface, but can d&d
it out side of it's container to the diagram (and model created in this case
will be invalid) that's definitely a problem and you can submit a request
for it.

BTW, there should be additional NodeC representing the diagram itself, so
XML you’ll get as a result should looks like:

<NodeC name=”Diagram”>
<NodeA name = "NodeA"/>
<NodeB name = "NodeB"/>
</NodeC>

I suppose in this case you can change your meta-model to prevent NodeB from
being created in NodeC (remove all containment references form NodeC to NodeB
– this could solve your problems for now.

Last question: are you using normal ECORE meta-model or you are creating
this meta-model from XSD?

Hi Alex,

I use XSD to create the meta-model.But now I am editing the ecore
directly . I removed the contaiment reference from nodeC and it seems to
work fine now .
One more question :

I have a case in which I have a collapsible compartment. This
compartment has a lot of nodes mapped on to it. When I hover my mouse on
to this node I want the the names of these nodes to be displayed.Is this
possible using GMF

Can you please submit a bugzilla entry for this problem - it should not
be possible to d&d node even if containment reference is specified in the
model, but there is no TopNodeReference.
