+\section{\class{wxDataObject}}\label{wxdataobject}
+
+A wxDataObject represents data that can be copied to or from the clipboard, or
+dragged and dropped.
+
+There are several predefined data object classes, such as \helpref{wxFileDataObject}{wxfiledataobject}, 
+\helpref{wxTextDataObject}{wxtextdataobject}, and \helpref{wxBitmapDataObject}{wxbitmapdataobject}.
+
+You may also derive your own data object classes for user-defined types.
+
+TODO: how do user-defined types work?
