Bentley.CifNET.GeometryModel.Tool.GeometryCommand.MultiObjectEntryState used to handle object in Bentley.CifNET.Graphics.IViewport.
Whenever I click an object in the IViewport with the mouse Left button, the object is added to a "container" in the MultiObjectEntryState class some where.and then,the protected override void OnObjectAdded(IButtonEvent buttonEvent, ObjectKey key) had been callback.
NOW,My question is:How do I remove this object from MultiObjectEntryState's "container" ?
I knewn in MultiObjectEntryState，similar to OnObjectAdded(), there is protected override void OnObjectRemoved(IButtonEvent buttonEvent, ObjectKey key)
But I don't know how to do to callback the OnObjectRemoved.
Explain what I said about the "container", when OnAfterSelection(IObjectKeyCollection selectedKeys) was callback, selectedKeys is the "container"。
