can be used without change or can be altered (by deriving a new class from them) in order to deliver
data and data size on-demand. There is no need to ever use wxDataObject itself or derive directly from it.
-You may also derive your own data object classes from \helpref{wxPrivateDataObject}{wxprivatedataobject}
+You may also derive your own data object classes from \helpref{wxPrivateDataObject}{wxprivatedataobject}
for user-defined types. The format of user-defined data is given as mime-type string literal,
such as "application/word" or "image/png". These strings are used as they are under Unix (so
far only GTK) to identify a format and are translated into their Windows equivalent under
Win32 (using the OLE IDataObject for data exchange to and from the clipboard and for Drag'n'Drop).
Note that the format string translation under Windows is not yet finnished.

As long as only one format is offerred, putting data directly into the clipboard may
be sufficient. But imagine that you paste a large piece of text to the clipboard and
Let's assume that you have written an HTML editor and want it to paste contents
in the formats "text/plain" and "text/html" to the clipboard. For offering

In your two derived classed you'd then have a pointer or reference to the central
data container and you'd override the methods returning the size of the
available data and the WriteData() methods in both classes.
