-<body>
-This demo shows some examples of data transfer through clipboard or
-drag and drop. In wxWindows, these two ways to transfer data (either
-between different applications or inside one and the same) are very
-similar which allows to implement both of them using almost the same
-code - or, in other words, if you implement drag and drop support for
-your application, you get clipboard support for free and vice versa.
-<p>
-At the heart of both clipboard and drag and drop operations lies the
-wxDataObject class. The objects of this class (or, to be precise,
-classes derived from it) represent the data which is being carried by
-the mouse during drag and drop operation or copied to or pasted from
-the clipboard. wxDataObject is a "smart" piece of data because it
-knows which formats it supports (see GetFormatCount and GetAllFormats)
-and knows how to render itself in any of them (see GetDataHere). It
-can also receive its value from the outside in a format it supports if
-it implements the SetData method. Please see the documentation of this
-class for more details.
-<p>
-Both clipboard and drag and drop operations have two sides: the source
-and target, the data provider and the data receiver. These which may
-be in the same application and even the same window when, for example,
-you drag some text from one position to another in a word
-processor. Let us describe what each of them should do.
