13
14wxDataObjectComposite is the simplest
15\helpref{wxDataObject}{wxdataobject} derivation which may be sued to support
16multiple formats. It contains several
17\helpref{wxDataObjectSimple}{wxdataobjectsimple} objects and supports any
18format supported by at least one of them. Only one of these data objects is
19{\it preferred} (the first one if not explicitly changed by using the second
20parameter of \helpref{Add}{wxdataobjectcompositeadd}) and its format determines
21the preferred format of the composite data object as well.
22
23See \helpref{wxDataObject}{wxdataobject} documentation for the reasons why you
24might prefer to use wxDataObject directly instead of wxDataObjectComposite for
25efficiency reasons.

62Adds the {\it dataObject} to the list of supported objects and it becomes the
63preferred object if {\it preferred} is true.
