-\subsection{Allocating and deleting wxWindows objects}
+\section{Allocating and deleting wxWindows objects}
 
 In general, classes derived from wxWindow must dynamically allocated
 with {\it new} and deleted with {\it delete}. If you delete a window,
 all of its children and descendants will be automatically deleted,
 so you don't need to delete these descendants explicitly.
 
-Don't statically create a window unless you know that the window
-cannot be deleted dynamically. Modal dialogs, such as those used
-in the {\tt dialogs} sample, can usually be created statically,
-if you know that the OK or Cancel button does not destroy the dialog.
+When deleting a frame or dialog, use {\bf Destroy} rather than {\bf delete} so
+that the wxWindows delayed deletion can take effect. This waits until idle time
+(when all messages have been processed) to actually delete the window, to avoid
+problems associated with the GUI sending events to deleted windows.
 
-Most drawing objects, such as wxPen, wxBrush, wxFont, and wxBitmap, should be
-created dynamically. They are cleaned up automatically on program exit.
-wxColourMap is an exception to this rule (currently). In particular,
-do not attempt to create these objects globally before OnInit() has a chance
-to be called, because wxWindows might not have done essential internal initialisation
-(including creation of lists containing all instances of wxPen, wxBrush etc.)
+Don't create a window on the stack, because this will interfere
+with delayed deletion.

-\section{Dynamic Link Libraries}
+\section{Architecture dependency}
+
+A problem which sometimes arises from writing multi-platform programs is that
+the basic C types are not defined the same on all platforms. This holds true
+for both the length in bits of the standard types (such as int and long) as 
+well as their byte order, which might be little endian (typically
+on Intel computers) or big endian (typically on some Unix workstations). wxWindows
+defines types and macros that make it easy to write architecture independent
+code. The types are:
 
-wxWindows may be used to produce DLLs which run under MS Windows. Note that
-this is not the same thing as having wxWindows as a DLL, which is not
-currently possible. For Microsoft C++, use the makefile with the argument DLL=1 to produce
-a version of the wxWindows library which may be used in a DLL application.
-There is a bug in Microsoft C++ which makes the compiler complain about returned floats,
-which goes away when the {\tt /Os} option is used, which is why that flag is
-set in the makefile.
+wxInt32, wxInt16, wxInt8, wxUint32, wxUint16 = wxWord, wxUint8 = wxByte
 
-For making wxWindows as a Sun dynamic library, there are comments in the
-UNIX makefile for the appropriate flags for AT\&T C++. Sorry, I haven't
-investigated the flags needed for other compilers.
+where wxInt32 stands for a 32-bit signed integer type etc. You can also check
+which architecture the program is compiled on using the wxBYTE\_ORDER define
+which is either wxBIG\_ENDIAN or wxLITTLE\_ENDIAN (in the future maybe wxPDP\_ENDIAN
+as well).
+
+The macros handling bit-swapping with respect to the applications endianness
+are described in the \helpref{Macros}{macros} section.
 
 \section{Conditional compilation}
 
 One of the purposes of wxWindows is to reduce the need for conditional
 compilation in source code, which can be messy and confusing to follow.
 However, sometimes it is necessary to incorporate platform-specific
-features (such as metafile use under MS Windows). The following identifiers
-may be used for this purpose, along with any user-supplied ones:
-
-\begin{itemize}
-\item {\tt wx\_x} - for code which should work under any X toolkit
-\item {\tt wx\_motif} - for code which should work under Motif only
-\item {\tt wx\_msw} - for code which should work under Microsoft Windows only
-\item {\tt wx\_xt} - for code which should work under Xt only
-\end{itemize}

-For example:

+\section{C++ issues}
 
-\section{Building on-line help}
+The following documents some miscellaneous C++ issues.
 
-wxWindows has its own help system from version 1.30: wxHelp. It can be
-used to view the wxWindows class library reference, and also to provide
-on-line help for your wxWindows applications. The API, made accessible
-by including {\tt wx\_help.h}, allows you to load files and display
-specific sections, using DDE to communicate between the application and
-wxHelp.
+\subsection{Templates}
 
-wxHelp files can be marked up by hand from ASCII files within wxHelp,
-or may be generated from other files, as is the case with the wxWindows
-documentation.
+wxWindows does not use templates since it is a notoriously unportable feature.
 
-It is possible to use the platform-specific help
-system (e.g. WinHelp) instead of wxHelp.
+\subsection{RTTI}
 
-See {\tt install.txt}, the wxHelp documentation (in {\tt
-utils/wxhelp/docs}) and \helpref{wxHelp}{wxhelp} for further details.
+wxWindows does not use run-time type information since wxWindows provides
+its own run-time type information system, implemented using macros.
 
-\section{C++ issues}
+\subsection{Type of NULL}
 
-There are cases where a C++ program will compile and run fine under one
-environment, and then fail to compile using a different compiler. Some
-caveats are given below, from experience with the GNU C++ compiler (GCC)
-and MS C/C++ compiler version 7.
+Some compilers (e.g. the native IRIX cc) define NULL to be 0L so that
+no conversion to pointers is allowed. Because of that, all these
+occurrences of NULL in the GTK port use an explicit conversion such 
+as
 
-\subsection{Templates}
+{\small
+\begin{verbatim}
+  wxWindow *my_window = (wxWindow*) NULL;
+\end{verbatim}
+}
 
-wxWindows does not use templates for two main reasons: one, it is a
-notoriously unportable feature, and two, the author is irrationally
-suspicious of them and prefers to use casts. More compilers are
-now implementing templates, and so it will probably be safe to use
-them soon without fear of portability problems.
+It is recommended to adhere to this in all code using wxWindows as
+this make the code (a bit) more portable.
