TObjectInspectorDlg has several public properties that may help:

Selection: TPersistentSelectionList
OnSelectionChange: TNotifyEvent
OnSelectPersistentsInOI: TNotifyEvent

also a boolean property EnableHookGetSelection which gives you access to 
protected get/set selection handlers.

There are possibly other relevant methods too, it is a complex class.
