-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 open source software, wxWindows has
-benefited from comments, ideas, bug fixes, enhancements and the sheer
-enthusiasm of users. 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 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, GTK+ 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 many extras such as network programming,
-PostScript output, and HTML rendering; and it can of course be extended as needs dictate. As a bonus, it provides
-a far cleaner and easier programming interface than the native
-APIs. Programmers may find it worthwhile to use wxWindows even if they
-are developing on only one platform.

+\section{Acknowledgements}
Thanks are due to AIAI for being willing to release the original version of
wxWindows into the public domain, and to our patient partners.
\section{Libraries}
-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.
+Most ports of wxWindows can create either a static library or a shared
+library. wxWindows can also be built in multilib and monolithic variants.
+See the \helpref{libraries list}{librarieslist} for more
+information on these.
\section{Configuration}
-Options are configurable in the file
+When using project files and makefiles directly to build wxWindows,
+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
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
+When using the 'configure' script to configure wxWindows (on Unix and other platforms where
+configure is available), the corresponding setup.h files are generated automatically
+along with suitable makefiles. 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. 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 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.
+On Microsoft Windows, wxWindows has a different set of makefiles for each
+compiler, because each compiler's 'make' tool is slightly different.
+Popular Windows compilers that we cater for, and the corresponding makefile
+extensions, include: Microsoft Visual C++ (.vc), Borland C++ (.bcc),
+OpenWatcom C++ (.wat) and MinGW/Cygwin (.gcc). Makefiles are provided
+for the wxWindows library itself, samples, demos, and utilities.
+
+On Linux, Mac and OS/2, you use the 'configure' command to
+generate the necessary makefiles. You should also use this method when
+building with MinGW/Cygwin on Windows.
+
+We also provide project files for some compilers, such as
+Microsoft VC++. However, we recommend using makefiles
+to build the wxWindows library itself, because makefiles
+can be more powerful and less manual intervention is required.
+
+On Windows using a compiler other than MinGW/Cygwin, you would
+build the wxWindows library from the build/msw directory
+which contains the relevant makefiles.
+
+On Windows using MinGW/Cygwin, and on Unix, MacOS X and OS/2, you invoke
+'configure' (found in the top-level of the wxWindows source hierarchy),
+from within a suitable empty directory for containing makefiles, object files and
+libraries.
+
+For details on using makefiles, configure, and project files,
+please see docs/xxx/install.txt in your distribution, where
+xxx is the platform of interest, such as msw, gtk, x11, mac.

is the following statement:
\begin{verbatim}
-rcinclude "wx/msw/wx.rc"
+#include "wx/msw/wx.rc"
\end{verbatim}
which includes essential internal wxWindows definitions. The resource script
so programs that search your executable for icons (such
as the Program Manager) find your application icon first.}
-\subsection{Module definition file}
-
-A module definition file (extension DEF) is required for 16-bit applications, and
-looks like the following:
-
-\begin{verbatim}

-STUB 'WINSTUB.EXE'
-CODE PRELOAD MOVEABLE DISCARDABLE
-DATA PRELOAD MOVEABLE MULTIPLE
-HEAPSIZE 1024
-STACKSIZE 8192
-\end{verbatim}

-The only lines which will usually have to be changed per application are
-NAME and DESCRIPTION.

-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,

-
-\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 modeled 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.
+In addition to the core wxWindows library, a number of further
+libraries and utilities are supplied with each distribution.
-Directed graphs may also be drawn using this library, if cycles are
-removed before the nodes and arcs are passed to the algorithm.
+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}.
-Tree displays are used in many applications: directory browsers,
-hypertext systems, class browsers, and decision trees are a few
-possibilities.
+For other user-contributed packages, please see the Contributions page
+on the \urlref{wxWindows Web site}{http://www.wxwindows.org}.
-See the separate manual and the directory utils/wxtree.
-
-\section{wxGraphLayout}
-
-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.
-
-See the separate manual and the directory utils/wxgraph.

\section{Strategies for debugging}\label{debugstrategies}
See the \helpref{debugging overview}{debuggingoverview} for further information.
-\subsection{Check Windows debug messages}
-
-Under Windows, it is worth running your program with
-\urlref{DbgView}{http://www.sysinternals.com} running or
-some other program that shows Windows-generated debug messages. It is
-possible it will show invalid handles being used. You may have fun seeing
-what commercial programs cause these normally hidden errors! Microsoft
-recommend using the debugging version of Windows, which shows up even
-more problems. However, I doubt it is worth the hassle for most
-applications. wxWindows is designed to minimize the possibility of such
-errors, but they can still happen occasionally, slipping through unnoticed
-because they are not severe enough to cause a crash.
-
-\subsection{Genetic mutation}
-
-If we had sophisticated genetic algorithm tools that could be applied
-to programming, we could use them. Until then, a common -- if rather irrational --
-technique is to just make arbitrary changes to the code until something
-different happens. You may have an intuition why a change will make a difference;
-otherwise, just try altering the order of code, comment lines out, anything
-to get over an impasse. Obviously, this is usually a last resort.
