\section{What is wxWindows?}
wxWindows is a C++ framework providing GUI (Graphical User
-Interface) and other facilities on more than one platform. Version 2.0 currently
-supports MS Windows (16-bit, Windows 95 and Windows NT), Unix with GTK+, and Unix with Motif.
-A Mac port is in an advanced state, an OS/2 port and a port to the MGL graphics library
-have been started.
+Interface) and other facilities on more than one platform. Version 2 currently
+supports all desktop versions of MS Windows, Unix with GTK+, Unix with Motif,
+and MacOS. An OS/2 port is in progress.
wxWindows was originally developed at the Artificial Intelligence
-Applications Institute, University of Edinburgh, for internal use.
-wxWindows has been released into the public domain in the hope
-that others will also find it useful. Version 2.0 is written and
-maintained by Julian Smart, Robert Roebling, Vadim Zeitlin and others.
+Applications Institute, University of Edinburgh, for internal use,
+and was first made publicly available in 1992.
+Version 2 is a vastly improved version written and maintained by
+Julian Smart, Robert Roebling, Vadim Zeitlin, Vaclav Slavik and many others.
-This manual discusses wxWindows in the context of multi-platform
-development.\helpignore{For more detail on the wxWindows version 2.0 API
-(Application Programming Interface) please refer to the separate
-wxWindows reference manual.}
+This manual contains a class reference and topic overviews.
+For a selection of wxWindows tutorials, please see the documentation page on the \urlref{wxWindows web site}{http://www.wxwindows.org}.
Please note that in the following, ``MS Windows" often refers to all
platforms related to Microsoft Windows, including 16-bit and 32-bit
\item support for a wide range of compilers.
\end{enumerate}
-Since wxWindows was started, several other free or almost-free GUI frameworks have
-emerged. However, none has the range of features, flexibility, documentation and the
-well-established development team that wxWindows has.
-
-As public domain software and a project open to everyone, wxWindows has
-benefited from comments, ideas, bug fixes, enhancements and the sheer
-enthusiasm of users, especially via the Internet. This gives wxWindows a
-certain advantage over its commercial competitors (and over free libraries
-without an independent development team), plus a robustness against
-the transience of one individual or company. This openness and
-availability of source code is especially important when the future of
-thousands of lines of application code may depend upon the longevity of
-the underlying class library.
-
-Version 2.0 goes much further than previous versions in terms of generality and features,
-allowing applications to be produced
-that are often indistinguishable from those produced using single-platform
-toolkits such as Motif and MFC.
-
-The importance of using a platform-independent class library cannot be
-overstated, since GUI application development is very time-consuming,
-and sustained popularity of particular GUIs cannot be guaranteed.
-Code can very quickly become obsolete if it addresses the wrong
-platform or audience. wxWindows helps to insulate the programmer from
-these winds of change. Although wxWindows may not be suitable for
-every application (such as an OLE-intensive program), it provides access to most of the functionality a
-GUI program normally requires, plus some extras such as network programming
-and PostScript output, and can of course be extended as needs dictate. As a bonus, it provides
-a cleaner programming interface than the native
-APIs. Programmers may find it worthwhile to use wxWindows even if they
-are developing on only one platform.

T.J. van Eijndhoven of Eindhoven University of Technology. The code has
\section{Libraries}
-Please the wxGTK or wxMotif documentation for use of the Unix version of wxWindows.
-Under Windows, use the library wx.lib for stand-alone Windows
-applications, or wxdll.lib for creating DLLs.
+The GTK and Motif ports of wxWindow can create either a static library or a shared
+library on most Unix or Unix-like systems. The static library is called libwx\_gtk.a
+and libwx\_motif.a whereas the name of the shared library is dependent on the
+system it is created on and the version you are using. The library name for the
+GTK version of wxWindows 2.2 on Linux and Solaris will be libwx\_gtk-2.2.so.0.0.0,
+on HP-UX, it will be libwx\_gtk-2.2.sl, on AIX just libwx\_gtk.a etc.
+
+Under Windows, use the library wx.lib (release) or wxd.lib (debug) for stand-alone Windows
+applications, or wxdll.lib (wxdlld.lib) for creating DLLs.
\section{Configuration}
Options are configurable in the file
-\rtfsp{\tt "wx/XXX/setup.h"} where XXX is the required platform (such as msw, motif, gtk, mac). Some settings are a matter
-of taste, some help with platform-specific problems, and
+\rtfsp{\tt "wx/XXX/setup.h"} where XXX is the required platform (such as msw, motif, gtk, mac). Some
+settings are a matter of taste, some help with platform-specific problems, and
others can be set to minimize the size of the library. Please see the setup.h file
and {\tt install.txt} files for details on configuration.
+Under Unix (GTK and Motif) the corresponding setup.h files are generated automatically
+when configuring the wxWindows using the "configure" script. When using the RPM packages
+for installing wxWindows on Linux, a correct setup.h is shipped in the package and
+this must not be changed.
+
\section{Makefiles}
At the moment there is no attempt to make Unix makefiles and
PC makefiles compatible, i.e. one makefile is required for
-each environment. wxGTK has its own configure system which can also
-be used with wxMotif, although wxMotif has a simple makefile system of its own.
-
-Sample makefiles for Unix (suffix .UNX), MS C++ (suffix .DOS and .NT), Borland
+each environment. The Unix ports use a sophisticated system based
+on the GNU autoconf tool and this system will create the
+makefiles as required on the respective platform. Although the
+makefiles are not identical in Windows, Mac and Unix, care has
+been taken to make them relatively similar so that moving from
+one platform to another will be painless.
+
+Sample makefiles for Unix (suffix .unx), MS C++ (suffix .DOS and .NT), Borland
C++ (.BCC and .B32) and Symantec C++ (.SC) are included for the library, demos
and utilities.
-The controlling makefile for wxWindows is in the platform-specific
-directory, such as {\tt src/msw} or {\tt src/motif}.
+The controlling makefile for wxWindows is in the MS-Windows
+directory {\tt src/msw} for the different Windows compiler and
+in the build directory when using the Unix ports. The build
+directory can be chosen by the user. It is the directory in
+which the "configure" script is run. This can be the normal
+base directory (by running {\tt ./configure} there) or any other
+directory (e.g. {\tt ../configure} after creating a build-directory
+in the directory level above the base directory).
Please see the platform-specific {\tt install.txt} file for further details.
\section{Architecture dependency}
A problem which sometimes arises from writing multi-platform programs is that
-the basic C types are not defiend the same on all platforms. This holds true
+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
as well).
The macros handling bit-swapping with respect to the applications endianness
-are described in the \helpref{Macros}{macros} section.
+are described in the \helpref{Byte order macros}{byteordermacros} section.
\section{Conditional compilation}
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
-occurences of NULL in the GTK port use an explicit conversion such
+occurrences of NULL in the GTK port use an explicit conversion such

\setfooter{\thepage}{}{}{}{}{\thepage}%
-A number of `extras' are supplied with wxWindows, to complement
-the GUI functionality in the main class library. These are found
-below the utils directory and usually have their own source, library
-and documentation directories. For other user-contributed packages,
-see the directory ftp://www.remstar.com/pub/wxwin/contrib, which is
-more easily accessed via the Contributions page on the Web site.
-
-\section{wxHelp}\label{wxhelp}
-
-wxHelp is a stand-alone program, written using wxWindows,
-for displaying hypertext help. It is necessary since not all target
-systems (notably X) supply an adequate
-standard for on-line help. wxHelp is modelled on the MS Windows help
-system, with contents, search and browse buttons, but does not reformat
-text to suit the size of window, as WinHelp does, and its input files
-are uncompressed ASCII with some embedded font commands and an .xlp
-extension. Most wxWindows documentation (user manuals and class
-references) is supplied in wxHelp format, and also in Windows Help
-format. The wxWindows 2.0 project will presently use an HTML widget
-in a new and improved wxHelp implementation, under X.
-
-Note that an application can be programmed to use Windows Help under
-MS Windows, and wxHelp under X. An alternative help viewer under X is
-Mosaic, a World Wide Web viewer that uses HTML as its native hypertext
-format. However, this is not currently integrated with wxWindows
-applications.
-
-wxHelp works in two modes---edit and end-user. In edit mode, an ASCII
-file may be marked up with different fonts and colours, and divided into
-sections. In end-user mode, no editing is possible, and the user browses
-principally by clicking on highlighted blocks.
-
-When an application invokes wxHelp, subsequent sections, blocks or
-files may be viewed using the same instance of wxHelp since the two
-programs are linked using wxWindows interprocess communication
-facilities. When the application exits, that application's instance of
-wxHelp may be made to exit also. See the {\bf wxHelpControllerBase} entry in the
-reference section for how an application controls wxHelp.
-
-\section{Tex2RTF}\label{textortf}
-
-Supplied with wxWindows is a utility called Tex2RTF for converting\rtfsp
-\LaTeX\ manuals to the following formats:
-
-\begin{description}
-\item[wxHelp]
-wxWindows help system format (XLP).
-\item[Linear RTF]
-Rich Text Format suitable for importing into a word processor.
-\item[Windows Help RTF]
-Rich Text Format suitable for compiling into a WinHelp HLP file with the
-help compiler.
-\item[HTML]
-HTML is the native format for Mosaic, the main hypertext viewer for
-the World Wide Web. Since it is freely available it is a good candidate
-for being the wxWindows help system under X, as an alternative to wxHelp.
-\end{description}
-
-Tex2RTF is used for the wxWindows manuals and can be used independently
-by authors wishing to create on-line and printed manuals from the same\rtfsp
-\LaTeX\ source. Please see the separate documentation for Tex2RTF.
-
-\section{wxTreeLayout}
-
-This is a simple class library for drawing trees in a reasonably pretty
-fashion. It provides only minimal default drawing capabilities, since
-the algorithm is meant to be used for implementing custom tree-based
-tools.
-
-Directed graphs may also be drawn using this library, if cycles are
-removed before the nodes and arcs are passed to the algorithm.
-
-Tree displays are used in many applications: directory browsers,
-hypertext systems, class browsers, and decision trees are a few
-possibilities.
-
-See the separate manual and the directory utils/wxtree.
+In addition to the core wxWindows library, a number of further
+libraries and utilities are supplied with each distribution.
-\section{wxGraphLayout}
+Some are under the 'contrib' hierarchy which mirrors the
+structure of the main wxWindows hierarchy. See also the 'utils'
+hierarchy. The first place to look for documentation about
+these tools and libraries is under the wxWindows 'docs' hierarchy,
+for example {\tt docs/htmlhelp/fl.chm}.
-The wxGraphLayout class is based on a tool called `graphplace' by Dr.
-Jos T.J. van Eijndhoven of Eindhoven University of Technology. Given a
-(possibly cyclic) directed graph, it does its best to lay out the nodes
-in a sensible manner. There are many applications (such as diagramming)
-where it is required to display a graph with no human intervention. Even
-if manual repositioning is later required, this algorithm can make a good
-first attempt.
+For other user-contributed packages, please see the Contributions page
+on the \urlref{wxWindows Web site}{http://www.wxwindows.org}.

overhead to your program; the overhead is compensated for by easier
manipulation (which means less code).

errors, but they can still happen occasionally, slipping through unnoticed
because they are not severe enough to cause a crash.
