+ - 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
