Hi,

Can someone show me how to delete/remove a node editpart from the
diagram manually/programmatically? I try the following:

Diagram diagram; // Diagram is AbstractGraphicalEditPart-derived class
Node node; // Node is AbstractGraphicalEditPart-derived class

// Error: removedChild(0 is not visible, it is a protected
// method in AbstractGraphicalEditPart.
diagram.removeChild(node);

Thanks
slam

Slam,

You will need to create an edit policy for this node, that extends component
policy. and implements createDeleteCommand(GroupRequest request). In this
method you will need to instatiate a command that deletes the node. If you
need more help let me know.

This should be available in logic example and schema diagram editor example.

More importantly, you delete the model, not the editpart. When your model
changes, the corresponding editpart will be automatically removed from the
diagram.
