+\membersection{wxDEPRECATED}\label{wxdeprecated}
+
+This macro can be used around a function declaration to generate warnings
+indicating that this function is deprecated (i.e. obsolete and planned to be
+removed in the future) when it is used. Only Visual C++ 7 and higher and g++
+compilers currently support this functionality.
+
+Example of use:
+\begin{verbatim}
+ // old function, use wxString version instead
+ wxDEPRECATED( void wxGetSomething(char *buf, size_t len) );
+
+ // ...
+ wxString wxGetSomething();
+\end{verbatim}
+
+
+\membersection{wxDEPRECATED\_BUT\_USED\_INTERNALLY}\label{wxdeprecatedbutusedinternally}
+
+This is a special version of \helpref{wxDEPRECATED}{wxdeprecated} macro which
+only does something when the deprecated function is used from the code outside
+wxWidgets itself but doesn't generate warnings when it is used from wxWidgets.
+It is used with the virtual functions which are called by the library itself --
+even if such function is deprecated the library still has to call it to ensure
+that the existing code overriding it continues to work, but the use of this
+macro ensures that a deprecation warning will be generated if this function is
+used from the user code or, in case of Visual C++, even when it is simply
+overridden.

-Used inside a class declaration to declare that the objects of this class should be dynamically
-creatable from run-time type information.
+Used inside a class declaration to make the class known to wxWidgets RTTI
+system and also declare that the objects of this class should be dynamically
+creatable from run-time type information. Notice that this implies that the
+class should have a default constructor, if this is not the case consider using
+\helpref{DECLARE\_CLASS}{declareclass}.
Example:
This macro is equivalent to {\tt wxDynamicCast(this, classname)} but the
latter provokes spurious compilation warnings from some compilers (because it
-tests whether {\tt this} pointer is non {\tt NULL} which is always true), so
+tests whether {\tt this} pointer is non-{\tt NULL} which is always true), so
this macro should be used to avoid them.

-The functions in this section deal with getting the current time and
-starting/stopping the global timers. Please note that the timer functions are
-deprecated because they work with one global timer only and
-\helpref{wxTimer}{wxtimer} and/or \helpref{wxStopWatch}{wxstopwatch} classes
-should be used instead. For retrieving the current time, you may also use
-\helpref{wxDateTime::Now}{wxdatetimenow} or
-\helpref{wxDateTime::UNow}{wxdatetimeunow} methods.

This function is called whenever one of debugging macros fails (i.e. condition
is false in an assertion). It is only defined in the debug mode, in release
To override the default behaviour in the debug builds which is to show the user
a dialog asking whether he wants to abort the program, continue or continue
ignoring any subsequent assert failures, you may override
-\helpref{wxApp::OnAssert}{wxapponassert} which is called by this function if
+\helpref{wxApp::OnAssertFailure}{wxapponassertfailure} which is called by this function if
the global application object exists.
Checks that the condition is true, returns with the given return value if not (FAILs in debug mode).
This check is done even in release mode.
