-// wxDataObject represents a piece of data which knows which formats it
-// supports and knows how to render itself in each of them - GetDataHere(),
-// and how to restore data from the buffer (SetData()).
-//
-// Although this class may be used directly (i.e. custom classes may be
-// derived from it), in many cases it might be simpler to use either
-// wxDataObjectSimple or wxDataObjectComposite classes.
-//
-// A data object may be "read only", i.e. support only GetData() functions or
-// "read-write", i.e. support both GetData() and SetData() (in principle, it
-// might be "write only" too, but this is rare). Moreover, it doesn't have to
-// support the same formats in Get() and Set() directions: for example, a data
-// object containing JPEG image might accept BMPs in GetData() because JPEG
-// image may be easily transformed into BMP but not in SetData(). Accordingly,
-// all methods dealing with formats take an additional "direction" argument
-// which is either SET or GET and which tells the function if the format needs
-// to be supported by SetData() or GetDataHere().
+DocStr(wxDataObject,
+"A wx.DataObject represents data that can be copied to or from the
+clipboard, or dragged and dropped. The important thing about
+wx.DataObject is that this is a 'smart' piece of data unlike usual
+'dumb' data containers such as memory buffers or files. Being 'smart'
+here means that the data object itself should know what data formats
+it supports and how to render itself in each of supported formats.
+
+**NOTE**: This class is an abstract base class and can not be used
+directly from Python. If you need a custom type of data object then
+you should instead derive from `wx.PyDataObjectSimple` or use
+`wx.CustomDataObject`.
+", "
+Not surprisingly, being 'smart' comes at a price of added
+complexity. This is reasonable for the situations when you really need
+to support multiple formats, but may be annoying if you only want to
+do something simple like cut and paste text.
+
+To provide a solution for both cases, wxWidgets has two predefined
+classes which derive from wx.DataObject: `wx.DataObjectSimple` and
+`wx.DataObjectComposite`. `wx.DataObjectSimple` is the simplest
+wx.DataObject possible and only holds data in a single format (such as
+text or bitmap) and `wx.DataObjectComposite` is the simplest way to
+implement a wx.DataObject which supports multiple simultaneous formats
+because it achievs this by simply holding several
+`wx.DataObjectSimple` objects.
+
+Please note that the easiest way to use drag and drop and the
+clipboard with multiple formats is by using `wx.DataObjectComposite`,
+but it is not the most efficient one as each `wx.DataObjectSimple`
+would contain the whole data in its respective formats. Now imagine
+that you want to paste 200 pages of text in your proprietary format,
+as well as Word, RTF, HTML, Unicode and plain text to the clipboard
+and even today's computers are in trouble. For this case, you will
+have to derive from wx.DataObject directly and make it enumerate its
+formats and provide the data in the requested format on
+demand. (**TODO**: This is currently not possible from Python. Make
+it so.)
+
+Note that the platform transfer mechanisms for the clipboard and drag
+and drop, do not copy any data out of the source application until
+another application actually requests the data. This is in contrast to
+the 'feel' offered to the user of a program who would normally think
+that the data resides in the clipboard after having pressed 'Copy' -
+in reality it is only declared to be available.
+");
+
+// [other docs...]
+// There are several predefined data object classes derived from
+// wxDataObjectSimple: wxFileDataObject, wxTextDataObject and
+// wxBitmapDataObject which can be used without change.
+
+// You may also derive your own data object classes from
+// wxCustomDataObject 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 and drop). Note that the format
+// string translation under Windows is not yet finished.
