Hi,

I have created a 'class diagram' like editor. Classes can be put into containers. The diagram typically represents the content of such container. However a diagram is capable of showing classes from different containers (by some kind of an import mechanism).

Now I would like to have the ability to 'highlight' the imported classes. So: default classes are yellow but imported ones are white. This I managed with a conditional style.

The point is that I don't always want to highlight the fact that classes are imported. Sometimes I just want to see all classes being yellow. The imported ones should become white after I apply a filter or a layer (or something else).

What is the preferred way to tackle this?

Is there a way to modify the appearance of an object via a tool?

Greetings,
Wilbert.

You could use a Style Customization [1] instead of a conditional style,
ahnd put that customization into a separate, optional layer. Then the
customization would only apply when the layer is enabled.

You can if you directly modify the style associated to the view, but
this requires knowledge of the Sirius metamodel. Note that if you do
this, for any feature you customize in a view's style you must add the
feature's name to the style's customFeatures attribute, or the
customization will be lost on the next refresh.
