Drag and Drop Functionality from Tree to Diagram in Sirius

[hoajie]

Hi Sirius team,

I hope you are doing well. I am currently working on a project using Sirius, where I have created a Tree Description. In this tree, I am using Diagram Creation to allow users to directly create diagrams from within the tree.

As shown in the image below, on the left side, there is a tree, and on the right side, there is a diagram that was created from the tree.

What I am trying to achieve:
I would like to implement a feature that allows dragging elements from the tree and dropping them directly onto the diagram on the right side. For example, in the attached image, I want to be able to drag an element like "action2" from the tree and drop it onto the diagram so that it is displayed there.

Question:
Could you provide any guidance or reference material on how to implement drag-and-drop functionality from a tree representation to a diagram in Sirius? Any advice or examples on how to get started with this feature would be greatly appreciated.

Thank you in advance for your help, and I look forward to your response!

Best regards,

Hi,
The test DragAndDropFromTableAndTreeToDiagramTest seems to be a good starting point. The associated data is here.

Yeah, so that means if i set the diagram as not synchronized,then i add the create view operation after drag n drop in odesign. After that i drag the instance from tree view to diagram, there will have a view created on the diagram. Is this description right?

Is this description right? Yes

So the view can create only single one too? If i don't add Create View operation, it still work, It's because dnd already add one , so the one that Create View created is duplicated and deleted by refresh.
