Example 2 with DestroyRequest

use of org.eclipse.gmf.runtime.emf.type.core.requests.DestroyRequest in project statecharts by Yakindu.

the class StatechartTextEditPart method createDefaultEditPolicies.

@Override

    super.createDefaultEditPolicies();
    // Disables deletion of the text compartment view if additional elements
    // are selected too

        protected boolean shouldProceed(DestroyRequest destroyRequest) {
            return false;
        }
    });
    // Disables deletion of the text compartment view via keyboard
    installEditPolicy(EditPolicy.COMPONENT_ROLE, new RootComponentEditPolicy());
