- the function principle of the windows clipboard:
a data provider offers all formats he can deliver on the clipboard
a clipboard client ask for the available formats on the clipboard
and decides if there is a format he can use
if there is one, he requests the data in this format
- This class inherits from IDataObject and so can be placed on the
OleClipboard. The class wraps a transferable object which is the
original DataSource
- DataFlavors offered by this transferable will be translated into
appropriate clipboard formats
- if the transferable contains text data always text and unicodetext
will be offered or vice versa
- text data will be automatically converted between text and unicode text
- although the transferable may support text in different charsets
(codepages) only text in one codepage can be offered by the clipboard
