void CXWindowsClipboard::close | ( | ) | const [virtual] |
Close clipboard.
Close the clipboard. close() must match a preceding successful open(). This signals that the clipboard has been filled with all the necessary data or all data has been read. It does not mean the clipboard ownership should be released (if it was taken).
