EA_OnPreNewDiagramObject

EA_OnPreNewDiagramObject notifies Add-Ins that a new diagram object is about to be dropped on a diagram. It enables Add-Ins to permit or deny creation of the new object.

This event occurs when a user drags an object directly from the Enterprise Architect Browser window or from the 'Resources' tab of the Browser window onto a diagram. The notification is provided immediately before the object is created, so that the Add-In can disable addition of the object.
