I would like to know how to Expand/Collapse all nodes inside my Diagram with a single click, from a tool in the Palette or using a Keyboard Key. any Ideas on how to do this ?

Hello

I guess you are taking about the ability to fold edges (and related nodes) using the "Folding Style" on the edgeMapping.

It is not currently possible natively.

To achieve that you have to implement your own action.
* add an action (from contextual menu on the diagram(you can contribute it in the odesign) or from diagram toolbar)
* call org.eclipse.sirius.diagram.ui.tools.internal.commands.ToggleFoldingStateCommand on each node that are folded. To know about the edge folded state : org.eclipse.sirius.diagram.ui.business.internal.query.EdgeTargetQuery.isFoldingPoint() or have a look to ToggleFoldingStateCommandto have usefull tips

Regards
Laurent

Hi Laurent,

Thank you for your answer. my first post was not clear, sorry for that.
Each node inside my diagram is a container and each Container has another container inside(Picture1 ) . I want to be able to fold/unfold the second container(Picture2) which is the behaviour that occurs when you click on the little + sign on the left. but I want to do that with one click and for all nodes.
I tried using a mapping filter that filters the second Container.
It works when I choose the Hide option but that is not what I need because I can't see the Description anymore(Picture3).
But nothing happens when I choose the Collapse option, which should get the right behaviour.

So how do you think I can fix this. or how can I reprocude this behaviour progammatically ?

Thanks in advance
