Enterprise Architect Add-in Framework Documentation
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 from the Enterprise Architect Project Browser or Resources 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. Also look at EA_OnPostNewDiagramObject.
