drawn in the diagram a new diagram opens.
And Bary gave me this link:

but where it is necessary to write these two portions of codes and is that
it is necessary to modify some properties of the concerned element
Somebody explains me this method
please

Hello Arij,

> but where it is necessary to write these two portions of codes and is
A: Starting from GMF 2.0 M2 you can use basic support for diagram partitioning
feature
So, looks like you should not modify generated code anymore.. Or did I misunderstand
you?

> it is necessary to modify some properties of the concerned element
You just have to modify .gnfgen model and regenerate code..

Hi,

You have to modify the gmfgen model. Under GenDiagram you can choose the
element (Edit part) for what you want to feature the double-click.
Right-Click in that element --> New Child --> OpenDiagramBehaviour.

(Well, you can do it also through gmfmap model. In nodeMapping set
relatedDiagrams under Misc and regenerate gmfGen)

There you have to fill two propeties: Diagram Kind and Editor Id.

(You can left they empty. Doing so performing doble-click will open a
diagram of the same type)

Then you have to regenerate. Now in your edit part an
openDiagramEditPolicy featuring the Open_ROle has been installed for the
selected edit part. When you perform double-click over that edit part in
the diagram that editPolicy will be called opening a new editor with the
semantic element of the right-clicked editPart as canvas.

Cheers!

Salva.

Hi Arij,

First we need to check that all the required stuff has been generated
properly. There have to be a class named OpenDiagramEditPolicy under
edit.policies and the view factory for the edit part must install in
CreateStyles the style HintedDiagramLinkStyle. Is all right? Then you can
try to set a breakpoint in OpenDiagramEditPolicy and see what happens when
double click is performed.

(You have also to check the values of properties Diagram Kind and Editor
ID)

Cheers!

Salva.

Hello Arij,

I googled and found: http://wiki.eclipse.org/Diagram_Partitioning

In general, you have to select NodeMapping representing diagram node with
associated sub-diagram and specify "related diagrams" for this node mapping.
This means - you have to point to the CanvasMapping representing sub-diagram
of this domain model element there. Then transform .gmfmap -> .gmfgen and
generate code.
