Change node icon programmatically [message #1693706]

Hello,

Is there any way to change the icon of a node in a Sirius editor programmatically?

I mean, I have a Representation of the model in a Sirius editor, and I would like to change the icon of a specific node on the canvas.

Therefore I created and added a new External Java Action in the odesign file, that receives all the views, and I iterate over each node, and I want to change the style / icon / graphical representation of a specified node. Is there any way to do it?

Thank you for help, in advance!

Best regards,
Ben

Hello,

I think you should use a Diagram Styles Customization (see
https://www.eclipse.org/sirius/doc/specifier/diagrams/Diagrams.html#customization).
You should create a "Property Customization (by expression)". In the
"Applied On" field, you select the style you want to replace the icon.
In the "value expression" you set the path of the new icon.

Regards,
Steve

Dear Steve,

Thank you for the advice, but I would like to enable for the users of my editor (created using Sirius) to change the icon only for one node from the specified types.

For example, I have Present Boxes, and I would like to enable that if the user double-clicks on a Present Box, then its icon will change for something else, while the other Present Boxes remain the same as they were before.

Can I do this using Sirius?

Thank you for help.

Best regards,
Ben

When the user double click on a Present Box, does it change something
somewhere in the model ? You could use this change/state in the
expression of the style customization mentionned by Steve to compute the
name of the icon you want to use.

Dear Maxime,

Unfortunately they are pretty identical from the model's point of view, it is just a View Model information.

I suppose I should develope a new model, which contains additional View Model information, which neither can be specified in the Sirius, nor in the original model (because it is not a domain information, rather a display information).

Thank you for all of your help.

Best regards,
Benedek

Hi Benedek,

You could also add some additional the aird.

There are several ways to do that:
. types like DDiagram accept some kind of annotations (DAnnotation, AnnotationEntry,..)
. the feature extensions mechanism can also be used to store an additional model in the aird.

You could take a look to the Graal modeler [1]:
. the metamodel of the feature extension is located in [2] and generated in [3]
. 2 classes to define the extension (see the declaration in the plugin.xml): org.obeonetwork.graal.design.extension.GraalFeatureExtension and GraalFeatureExtensionService
. One service class to manipulate/set/get the data: org.obeonetwork.graal.design.services.configuration.UIConfigurationServices , which uses FeatureExtensionsManager.INSTANCE.saveFeatureExtensionData and FeatureExtensionsManager.INSTANCE.retrieveFeatureExtensionData

Regards
