|
|
- 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 an so can be placed on the
|
|
OleClipboard. The class wrapps a transferable object which is the
|
|
original DataSource
|
|
- DataFlavors offerd 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 automaticaly converted between text und unicode text
|
|
- although the transferable may support text in different charsets
|
|
(codepages) only text in one codepage can be offered by the clipboard
