How to add Collapse All / Expand All menu option in GMF [message #1058647]

Hello GMF Experts!

I just like to ask if you know a way to add a menu option to Collapse All / Expand All compartments in a diagram.

In the diagram, I have figures that have parent-child relationship (a Figure within a figure). The structure can be huge so its going to be a bit tedious to go through all compartments and try to collapse/expand.

Is there any link that shows how to do this? Or may be you can point me into something that I can start looking into?

Appreciate your response. Thanks!

Hi,

you could add an editpolicy to the compartment edit part showing a pop up offering this option. Or you could extend GMF's default popup-bar to offer this. If you always want to expand all children you could listen to the notational model and also expand the children.

Thanks, your response was helpful. What I did was extended the popup contributions and added the collpase/expand actions.

However, I have one more question, everytime I call these actions, it makes my graphical editor dirty.

Is there a way not to make the editor dirty when collapse/expand the compartments?

I just want to make the editor dirty when there are semantic model changes. Is this doable?
