\section{\class{wxClipboard}}\label{wxclipboard}
A class for manipulating the clipboard. Note that this is not compatible with the
-clipboard class from wxWindows 1.xx, which has the same name but a different implementation.
+clipboard class from wxWidgets 1.xx, which has the same name but a different implementation.
To use the clipboard, you call member functions of the global {\bf wxTheClipboard} object.
-Call \helpref{wxClipboard::Open}{wxclipboardopen} to get ownership of the clipboard. If this operation returns TRUE, you
-now own the clipboard. Call \helpref{wxClipboard::AddData}{wxclipboardadddata} to put data
-on the clipboard (one or more times), or \helpref{wxClipboard::GetData}{wxclipboardgetdata} to

retrieve data from the clipboard. Call \helpref{wxClipboard::Close}{wxclipboardclose} to close
the clipboard and relinquish ownership. You should keep the clipboard open only momentarily.

-Call this function to add a data object to the clipboard. This function can be called several times
-to put different formats on the clipboard.
+Call this function to add the data object to the clipboard. You may call
+this function repeatedly after having cleared the clipboard using \helpref{wxClipboard::Clear}{wxclipboardclear}.

+After this function has been called, the clipboard owns the data, so do not delete
+the data explicitly.

Call this function to close the clipboard, having opened it with \helpref{wxClipboard::Open}{wxclipboardopen}.
+\membersection{wxClipboard::Flush}\label{wxclipboardflush}
+
+\func{bool}{Flush}{\void}
+
+Flushes the clipboard: this means that the data which is currently on
+clipboard will stay available even after the application exits (possibly
+eating memory), otherwise the clipboard will be emptied on exit.
+Returns false if the operation is unsuccessful for any reason.

-\func{bool}{GetData}{\param{wxDataObject&}{ data}}

Call this function to fill {\it data} with data on the clipboard, if available in the required

+\membersection{wxClipboard::IsOpened}\label{wxclipboardisopened}
+
+\constfunc{bool}{IsOpened}{\void}
+
+Returns true if the clipboard has been opened.
\membersection{wxClipboard::IsSupported}\label{wxclipboardissupported}
-\func{bool}{IsSupported}{\param{wxDataObject&}{ data}}
+\func{bool}{IsSupported}{\param{const wxDataFormat\&}{ format}}
-Returns TRUE if the format of the given data object is available on the clipboard.
+Returns true if there is data which matches the data format of the given data object currently {\bf available} (IsSupported sounds like a misnomer, FIXME: better deprecate this name?) on the clipboard.
\membersection{wxClipboard::Open}\label{wxclipboardopen}
Call \helpref{wxClipboard::Close}{wxclipboardclose} when you have finished with the clipboard. You
should keep the clipboard open for only a very short time.
-Returns TRUE on success. This should be tested (as in the sample shown above).

clear all previous contents in the clipboard, so calling it several times
does not make any sense.
