wxWindows is a C++ framework providing GUI (Graphical User
Interface) and other facilities on more than one platform. Version 2.0 currently
-supports subsets MS Windows (16-bit, Windows 95 and Windows NT) and GTK.
+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

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 and others.

This manual discusses wxWindows in the context of multi-platform

wxWindows was developed to provide a cheap and flexible way to maximize
investment in GUI application development. While a number of commercial
-class libraries already exist for cross-platform development,
+class libraries already existed for cross-platform development,
none met all of the following criteria:
\begin{enumerate}\itemsep=0pt
\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

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 brothers, and a robustness against
+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.
-In writing wxWindows, completeness has sometimes been traded for
-portability and simplicity of programming. Version 2.0 goes much
-further than previous versions in terms of generality and features,

The importance of using a platform-independent class library cannot be
overstated, since GUI application development is very time-consuming,

these winds of change. Although wxWindows may not be suitable for
-every application, it provides access to most of the functionality a
-GUI program normally requires, plus some extras such as form

APIs. Programmers may find it worthwhile to use wxWindows even if they
are developing on only one platform.

\section{Libraries}
-Please the wxGTK documentation for use of the Unix version of wxWindows.
+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 for stand-alone Windows
applications, or wxdll.lib for creating DLLs.
\section{Configuration}
-The following lists the options configurable in the file
-\rtfsp{\tt "wx/msw/setup.h"} and {\tt "wx/gtk/setup.h"} 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.

-\twocolitem{USE\_WX\_RESOURCES}{If 1, wxWindows resource file (.WXR) code is compiled.}
-\end{twocollist}
-
-\subsection{Windows and NT features}
-
-\begin{twocollist}
-\twocolitem{CTL3D}{CTL3D should only be used for 16-bit Windows programs.
-On Windows 95 and NT, native 3D effects are used. If you want to
-use it and don't already have CTL3D installed, copy the files in
-contrib/ctl3d to appropriate places (ctl3dv2.lib/ctl3d32.lib into your compiler lib
-directory, ctl3d.h into an include directory, and ctl3dv2.dll into
-windows/system). You may need to find a compiler-specific version of ctl3dv2.lib

-or ctl3d32.lib.}
-\twocolitem{USE\_ODBC}{If 1, compiles wxDatabase and wxRecordSet classes for ODBC
-access. Requires sql.h, sqlext.h files if set to 1 (see topic on database support).}
-\end{twocollist}
+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
+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.
-
-Sample makefiles for Unix (suffix .UNX), MS C++ (suffix .DOS and .NT), Borland
-C++ (.BCC) and Symantec C++ (.SC) are included for the library, demos
-and utilities. The NT, Borland and Symantec makefiles cannot be
-guaranteed to be up-to-date since the author does not have
-these compilers.
-
-The controlling makefile for wxWindows is in the platform-specific
-directory, such as {\tt src/msw} or {\tt src/x}. This makefile will
-recursively execute the makefile in {\tt src/base}.
-
-\subsection{Windows makefiles}
-
-For Microsoft C++, normally it is only necessary to type {\tt nmake -f
-makefile.dos} (or an alias or batch file which does this). By default,
-binaries are made with debugging information, and no optimization. Use
-FINAL=1 on the command line to remove debugging information (this only
-really necessary at the link stage), and DLL=1 to make a DLL version of
-the library, if building a library.
-
-\subsection{Unix makefiles}
-
-TODO.
-
-Debugging information is included by default; you may add DEBUG= as an
-argument to make to compile without it, or use the Unix {\bf strip}
-command to remove debugging information from an executable.
-
-\normalbox{{\it Important note:} Most compiler flags are kept centrally in
-src/make.env, which is included by all other makefiles. This is the
-file to edit to tailor wxWindows compilation to your environment.}
+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.
\section{Windows-specific files}
The only lines which will usually have to be changed per application are
NAME and DESCRIPTION.
-\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,
a drawing object that may be in use. Code that doesn't do this will probably work
fine on some platforms, and then fail under Windows.
+\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
+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:
+
+wxInt32, wxInt16, wxInt8, wxUint32, wxUint16 = wxWord, wxUint8 = wxByte
+
+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:

+\subsection{Type of NULL}
-{\bf wxWindows modes:}
+Some compilers (e.g. the native IRIX cc) define NULL to be 0L so that

+occurences of NULL in the GTK port use an explicit conversion such
+as

-\subsection{Templates}
-
-wxWindows does not use templates since it is a notoriously unportable feature.
+It is recommended to adhere to this in all code using wxWindows as

\subsection{Precompiled headers}
Some compilers, such as Borland C++ and Microsoft C++, support
precompiled headers. This can save a great deal of compiling time. The
-recommended approach is to precompile {\tt ``wx.h''}, using this
+recommended approach is to precompile {\tt "wx.h"}, using this
precompiled header for compiling both wxWindows itself and any
wxWindows applications. For Windows compilers, two dummy source files
are provided (one for normal applications and one for creating DLLs)
is that to take advantage of the facility, you often need to include
more header files than would normally be the case. This means that
changing a header file will cause more recompilations (in the case of
-wxWindows, everything needs to be recompiled since everything includes
-{\tt ``wx.h''}!)
+wxWindows, everything needs to be recompiled since everything includes {\tt "wx.h"}!)
A related problem is that for compilers that don't have precompiled
headers, including a lot of header files slows down compilation
information. The application searches through a number of locally
defined directories to find the file. To support this, the class {\bf
wxPathList} makes adding directories and searching for files easy, and
-the global function {\bf FileNameFromPath} allows the application to
+the global function {\bf wxFileNameFromPath} allows the application to
strip off the filename from the path if the filename must be stored.
This has undesirable ramifications for people who have documents of the
same name in different directories.

descriptions of miscellaneous file handling functions.
