\section{\class{wxClipboard}}\label{wxclipboard}
A class for manipulating the clipboard. Note that this is not compatible with the

To use the clipboard, you call member functions of the global {\bf wxTheClipboard} object.

now own the clipboard. Call \helpref{wxClipboard::SetData}{wxclipboardsetdata} to put data
on the clipboard, or \helpref{wxClipboard::GetData}{wxclipboardgetdata} to
retrieve data from the clipboard. Call \helpref{wxClipboard::Close}{wxclipboardclose} to close

+\func{bool}{AddData}{\param{wxDataObject*}{ data}}
+
+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

\membersection{wxClipboard::Clear}\label{wxclipboardclear}
\func{void}{Clear}{\void}
Clears the global clipboard object and the system's clipboard if possible.

\membersection{wxClipboard::Close}\label{wxclipboardclose}
-\func{bool}{Close}{\void}
+\func{void}{Close}{\void}
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.

\membersection{wxClipboard::GetData}\label{wxclipboardgetdata}
\func{bool}{GetData}{\param{wxDataObject\&}{ data}}
Call this function to fill {\it data} with data on the clipboard, if available in the required
-format. Returns TRUE on success.

+\constfunc{bool}{IsOpened}{\void}
+
+Returns true if the clipboard has been opened.

\membersection{wxClipboard::IsSupported}\label{wxclipboardissupported}
\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.

clear all previous contents in the clipboard, so calling it several times

-\func{void}{UsePrimarySelection}{\param{bool}{ primary = TRUE}}
+\func{void}{UsePrimarySelection}{\param{bool}{ primary = true}}
-On platforms supporting it (currently only GTK), selects the so called
-PRIMARY SELECTION as the clipboard as opposed to the normal clipboard,
-if {\it primary} is TRUE.
+On platforms supporting it (all X11-based ports), wxClipboard uses the
+CLIPBOARD X11 selection by default. When this function is called with \true
+argument, all subsequent clipboard operations will use PRIMARY selection until
+this function is called again with \false.
+On the other platforms, there is no PRIMARY selection and so all clipboard
+operations will fail. This allows to implement the standard X11 handling of the
+clipboard which consists in copying data to the CLIPBOARD selection only when
+the user explicitly requests it (i.e. by selection \texttt{"Copy"} menu
+command) but putting the currently selected text into the PRIMARY selection
+automatically, without overwriting the normal clipboard contents with the
+currently selected text on the other platforms.
