+\membersection{wxCHECK\_VISUALC\_VERSION}\label{wxcheckvisualcversion}
+
+\func{bool}{wxCHECK\_VISUALC\_VERSION}{\param{}{major}}
+
+Returns $1$ if the compiler being used to compile the code is Visual C++
+compiler version \arg{major} or greater. Otherwise, and also if
+the compiler is not Visual C++ at all, returns $0$.
+
+
\membersection{wxCHECK\_W32API\_VERSION}\label{wxcheckw32apiversion}
\func{bool}{wxCHECK\_W32API\_VERSION}{\param{}{major, minor, release}}
Calling wxHandleFatalExceptions() with {\it doIt} equal to false will restore
this default behaviour.
+Notice that this function is only available if
+\texttt{wxUSE\_ON\_FATAL\_EXCEPTION} is $1$ and under Windows platform this
+requires a compiler with support for SEH (structured exception handling) which
+currently means only Microsoft Visual C++ or a recent Borland C++ version.

+\membersection{wxS}\label{wxs}
+
+\func{wxStringCharType}{wxS}{\param{char }{ch}}
+
+\func{const wxStringCharType *}{wxS}{\param{const char *}{s}}
+
+wxS is macro which can be used with character and string literals to either
+convert them to wide characters or strings in \texttt{wchar\_t}-based Unicode
+builds or keep them unchanged in UTF-8 builds. The use of this macro is
+optional as the translation will always be done at run-time even if there is a
+mismatch between the kind of the literal used and wxStringCharType used in the
+current build, but using it can be beneficial in performance-sensitive code to
+do the conversion at compile-time instead.

\func{int}{wxStrcmp}{\param{const char *}{p1}, \param{const char *}{p2}}
Ring the system bell.
+Note that this function is categorized as a GUI one and so is not thread-safe.

+\membersection{::wxInfoMessageBox}\label{wxinfomessagebox}

+\func{void}{wxInfoMessageBox}{\param{wxWindow (}{parent = \NULL}}
+
+Shows a message box with the information about the wxWidgets build used,
+including its version, most important build parameters and the version of the
+underlying GUI toolkit. This is mainly used for diagnostic purposes and can be
+invoked by Ctrl-Alt-middle clicking on any wxWindow which doesn't otherwise
+handle this event.

\membersection{::wxSetCursor}\label{wxsetcursor}
-\func{void}{wxSetCursor}{\param{wxCursor *}{cursor}}
+\func{void}{wxSetCursor}{\param{const wxCursor\&}{ cursor}}
+
+Globally sets the cursor; only has an effect on Windows, Mac and GTK+. You should
+call this function with wxNullCursor to restore the system cursor.
-Globally sets the cursor; only has an effect in Windows and GTK.
See also \helpref{wxCursor}{wxcursor}, \helpref{wxWindow::SetCursor}{wxwindowsetcursor}.
The clipboard must have previously been opened for this call to succeed.

+\func{}{wxCONCAT3}{\param{}{x1}, \param{}{x2}, \param{}{x3}}

-This macro returns the concatenation of two tokens \arg{x} and \arg{y}.
+\func{}{wxCONCAT5}{\param{}{x1}, \param{}{x2}, \param{}{x3}, \param{}{x4}, \param{}{x5}}
+
+These macro return the concatenation of the tokens passed as their arguments.
+Unlike when using the preprocessor \texttt{##} operator, the arguments undergo
+the macro expansion before being concatenated.

+\membersection{wxDECLARE\_APP}\label{wxdeclareapp}
+
+\func{}{wxDECLARE\_APP}{className}
+
+This is used in headers to create a forward declaration of the
+\helpref{wxGetApp}{wxgetapp} function implemented by
+\helpref{wxIMPLEMENT\_APP}{wximplementapp}. It creates the declaration
+{\tt className\& wxGetApp(void)}.
+

Returns the current state of the mouse. Returns a wxMouseState
instance that contains the current position of the mouse pointer in
-screen coordinants, as well as boolean values indicating the up/down
+screen coordinates, as well as boolean values indicating the up/down
status of the mouse buttons and the modifier keys.

+\membersection{wxFORCE\_LINK\_THIS\_MODULE}\label{wxforcelinkthismodule}
+
+\func{}{wxFORCE\_LINK\_THIS\_MODULE}{moduleName}
+
+This macro can be used in conjunction with the
+\helpref{wxFORCE\_LINK\_MODULE}{wxforcelinkmodule} macro to force
+the linker to include in its output a specific object file.
+
+In particular, you should use this macro in the source file which you want
+to force for inclusion. The \tt{moduleName} needs to be a name not already
+in use in other \tt{wxFORCE\_LINK\_THIS\_MODULE} macros, but is not required
+to be e.g. the same name of the source file (even if it's a good choice).

+\func{}{wxFORCE\_LINK\_MODULE}{moduleName}
+
+This macro can be used in conjunction with the
+\helpref{wxFORCE\_LINK\_THIS\_MODULE}{wxforcelinkthismodule} macro to force
+the linker to include in its output a specific object file.
+
+In particular, you should use this macro in a source file which you know
+for sure is linked in the output (e.g. the source file containing the "main()"
+of your app). The \tt{moduleName} is the name of the module you want to forcefully link
+(i.e. the name you used in the relative \helpref{wxFORCE\_LINK\_THIS\_MODULE}{wxforcelinkthismodule} macro.

+
+This is used in the application class implementation file to make the application class
+known to wxWidgets for dynamic construction. You use this as:

+\begin{verbatim}
+ wxIMPLEMENT_APP(MyApp)
