When a node is selected on the genogram diagram, pressing the “delete” key deletes that node. How can I disable this. I don’t want it to any react when I press the “delete” button.
You have several choices, depending on exactly the behavior that you want.
- you could set Part.deletable to false on the node templates
- you could set Diagram.allowDelete to false in the diagram initialization
- you could set Diagram.isReadOnly to true in the diagram initialization
