Greetings,
I have some symbols which have compartments. The generated GMF editor does
not allow me neither to start, nor to end a link on a symbol's compartment.
I can do this only if I start or end the link on the symbol's title area.
Where should I modify the generated code so that the compartment can become
a valid link source & target?
Thanks in advance,
Kalin

Hello Kalin and Alex,
I have another suggestion: I think it would be cool if the popup-box for
selecting an element type to create or an existing element, that appears
when ending a connection on top of a compartment, could be given another
line: "create connection to this element". Alex, can you tell me where
I'd have to look in order to add this feature?

tobias

Hello Alex,
you are right, it works in the Ecore diagram editor, but this is because
these compartments have a list layout. I tried it in my diagram editor,
and for those compartments that have a list layout (in my case, a BPMN
pool) links can be ended ontop of the compartment, while for
compartments with an XY layout (e.g. BPMN subprocess) they can not.
There seem to be some other curious differences between these two types
of compartments I wasn't aware of until now. E.g., it seems that in a
figure with a list layout compartment you can drop a new element from
the palette on the label, while for an XY layout compartment you have to
target the compartment itself (makes sense, as in the latter case the
figure needs some coordinates). I think I'll try to investigate the
differences between these two types of compartments in my diagram code.
Regards,
Tobias

Hi Kalin,
Hi Alex,
Hi Tobias,
I want to have the same feature as you want Kalin but without infinite
level, I want node which have links on elements in Compartement of other
Nodes (these nodes are similar to UMLClass with Property in Compartement).
If I set "List Layout" in my gmfgen to false, my compartment elements
disappears.
Alex, Tobias, you have said that with EcoreTools, we can add links to
elements in Compartement, I suppose you talk about Package node?
I would like to add link ending to property like in UMLClass with a
StackLayout in my gmfgraph.
How can do it?
