Change dynamicaly Figure for Link or Node [message #96226]

Wed, 24 January 2007 14:04

Eclipse User

Hi all,

I want to know if it's possible to change the Figure of an element (link
or node) without destroy and recreate it.

For example in a diagram when I change the type of a link I want that
the figure changes automatically (type EXTENDS = dash arrow , type
INCLUDES = solid arrow, etc...)

Thanks in advance,

Hugues

Hello Hugues_Rérolle,

Currently this functionality is not supported by generated code, so you have
to write it manually - you can add a listener to the underlying semantic/notation
model element and change figure in accordance.

Hi Hugues,

Currently, support for this is only generated in the lite runtime. You would
need to define several node (or link) mappings with different visual
representations,
associate each with a constraint and a feature seq initializer (constraints
should be mutually inclusive and collectively exhaustive, and the feature
seq initializers should
initialize the elements to match the corresponding constraint). An example
of such a makeup for a link can be found in the MindMap example.

Best regards,
Boris Blajer

Hello Alex,

Thanks for your response, I'll do that manually.

Thanks for your answers Boris,

I did the mindmap tutorial, and It's not exactly that I want to do.
Because it's impossible to convert a link to another link, you have to
destroy and recreate It...

But Alex Shatalin has given the answer:

As Boris mentioned, my answer is valid for _runtime_based_ generated code.
In addition to it GMF support _lite_ diagram code generation ( http://wiki.eclipse.org/index.php/GMF_Tutorial_Part_4#Lite_R untime_Generation_to_RCP).
So, if you need this updating functionality you can try lite code generation
- corresponding feature is implemented there AFAIK.

Hi Alex & Boris,

I'm interested by the lite diagram code generation. But I have some
execution problem when I generate the pure GEF-diagram code (I can't add
node in the diagram...), but it's another problem.

Thanks again to both of you.

Hugues

Hi Hugues,

What exactly is your execution problem in the lite version? Do you have any
stacktrace or any other manifestation of what is going wrong?

Best regards,
Boris

Hi Boris,

I found the problem, I forgot to clear both options "Use ImapMode" and
"utilize enhanced features of GMF runtime" ;).

Sorry for my lack of understanding.

Regards,

Hugues
