Browse Source 
2. Added IsUsingPrimarySelection()
3. Fail all clipboard operations when IsUsingPrimarySelection() is true on
   non-X11 platforms

\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.
