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