|
|
|
* NOTES:
|
|
|
|
* This file contains the implementation for the OLE Clipboard and its
|
|
|
|
* internal interfaces. The OLE clipboard interacts with an IDataObject
|
|
|
|
* interface via the OleSetClipboard, OleGetClipboard and
|
|
|
|
* OleIsCurrentClipboard API's. An internal IDataObject delegates
|
|
|
|
* to a client supplied IDataObject or the WIN32 clipboard API depending
|
|
|
|
* on whether OleSetClipboard has been invoked.
|
|
|
|
* Here are some operating scenarios:
|
|
|
|
*
|
|
|
|
* 1. OleSetClipboard called: In this case the internal IDataObject
|
|
|
|
* delegates to the client supplied IDataObject. Additionally OLE takes
|
|
|
|
* ownership of the Windows clipboard and any HGLOCBAL IDataObject
|
|
|
|
* items are placed on the Windows clipboard. This allows non OLE aware
|
|
|
|
* applications to access these. A local WinProc fields WM_RENDERFORMAT
|
|
|
|
* and WM_RENDERALLFORMATS messages in this case.
|
|
|
|
*
|
|
|
|
* 2. OleGetClipboard called without previous OleSetClipboard. Here the internal
|
|
|
|
* IDataObject functionality wraps around the WIN32 clipboard API.
|
|
|
|
*
|
|
|
|
* 3. OleGetClipboard called after previous OleSetClipboard. Here the internal
|
|
|
|
* IDataObject delegates to the source IDataObjects functionality directly,
|
|
|
|
* thereby bypassing the Windows clipboard.
|
|
|
|
*
|
|
|
|
* Implementation references : Inside OLE 2'nd edition by Kraig Brockschmidt
|
|
|
|
*
|
|
|
|
* TODO:
|
|
|
|
* - Support for pasting between different processes. OLE clipboard support
|
|
|
|
* currently works only for in process copy and paste. Since we internally
|
|
|
|
* store a pointer to the source's IDataObject and delegate to that, this
|
|
|
|
* will fail if the IDataObject client belongs to a different process.
|
|
|
|
* - IDataObject::GetDataHere is not implemented
|
|
|
|
* - OleFlushClipboard needs to additionally handle TYMED_IStorage media
|
|
|
|
* by copying the storage into global memory. Subsequently the default
|
|
|
|
* data object exposed through OleGetClipboard must convert this TYMED_HGLOBAL
|
|
|
|
* back to TYMED_IStorage.
|
|
|
|
* - OLE1 compatibility formats to be synthesized from OLE2 formats and put on
|
|
|
|
* clipboard in OleSetClipboard.
