Gets the object identified by the iterator, then sets the iterator to the previous object in the selection.

syntaxSyntax:
DlxSelection.GetPrevObject(iterator)

Parameters

Parameter Description
iterator A DlxIterator value returned by a previous GetPrevObject, GetTailObjectIterator, or other function call.

Return Value

Returns the DlxObject corresponding to the iterator. Call the IsValid() method to determine if the object is valid.
