Detailed Description

Clipboard implementation.

Registers a non-visible clipboard viewer window that receives clipboard events in its own window procedure to be able to receive clipboard-changed events, which QPlatformClipboard needs to emit. That requires housekeeping of the next in the viewer chain.

Note

The OLE-functions used in this class require OleInitialize().
