When creating a model with the Sirius Diagram Editor, the style of the diagram elements can be modified according to the user's requirements: the elements can be resized, the color can be changed and images can be used to represent the elements.   The user experience has been improved with Sirius 7.0.0 to use images in diagrams. This new feature is available through the “Set style to Workspace Ima...

When creating your own graphical modeler using Eclipse Sirius Desktop , you need to tell Sirius: how to interpret your domain models so they can be displayed, and how your domain elements must be modified when the end-user invokes edition tools (e.g. direct edit, element creation or deletion, etc.). This is done using a combination of interpreted expressions (in general using AQL ) and model opera...

Since my early childhood I have loved stories, listening to books read by my mum, then reading by myself comics or classical literature for school and now, as I dedicate not so much time to reading, mostly blog posts and news on the internet.

For a while now, Sirius has integrated ELK (Eclipse Layout Kernel)  to make it easier to define your own custom diagram layouts.  ELK provides  several layout styles  that can be used directly .
