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.

In your two derived classed you'd then have a pointer or reference to the central

available data and the WriteData() methods in both classes.
