wxWindows is a C++ framework providing GUI (Graphical User
Interface) and other facilities on more than one platform. Version 2.0 currently

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

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.

The importance of using a platform-independent class library cannot be
overstated, since GUI application development is very time-consuming,
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, it provides access to most of the functionality a
-GUI program normally requires, plus some extras such as form
-construction, interprocess communication 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.

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
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)

more header files than would normally be the case. This means that
changing a header file will cause more recompilations (in the case of

A related problem is that for compilers that don't have precompiled
headers, including a lot of header files slows down compilation
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

Don't use absolute panel item positioning if you can avoid it. Different GUIs have
very differently sized panel items. Consider using the constraint system, although this

Alternatively, you could use alternative .wrc (wxWindows resource files) on different
