14 \begin{center}
15         {\Large{\bf Welcome to the wonderful world of PWLib}}
16 \end{center}
18 PWLib is a moderately large class library that has its genesis many years ago as
19 a method to product applications to run on both Microsoft Windows and Unix
20 X-Windows systems. It also was to have a Macintosh port as well but this never
21 eventuated.
23 Since then the system has grown to having quite good application to areas other
24 than mere Windows GUI portability. Classes for I/O portability, multi-threading
25 portability, aid in producing unix daemons and NT services portably and all
26 sorts of internet protocols were added over the years.
28 All this over and above basic "container" classes such as arrays, linear lists,
29 sorted lists (RB Tree) and dictionaries (hash tables) which were all created
30 before STL became the answer to all our prayers. Unfortunately, due to intertia
31 and the GNU C++ inadequate support of templates, this library will probably not
32 be ported to STL in the near future.
34 The library was used extensively for all our in-house products. Then we decided
35 to support the open H323 project by throwing in some of the code written for
36 one of our products. Thus, required PWLib so it got thrown into the open source
37 world as well.

44 /**@name        Using PWLib
45 Detailed tutorials will almost certainly not be forthcoming. However,
46 at least giving you an indication on how to start an application would
47 be usefull, so here is the infamous "Hello world!" program.
48 \begin{verbatim}
49 // hello.cxx
51 #include <ptlib.h>
53 class Hello : public PProcess
55   PCLASSINFO(Hello, PProcess)
56   public:
57         void Main();
60 PCREATE_PROCESS(Hello)
62 void Hello::Main()
64   cout << "Hello world!\n";
67 // End of hello.cxx
68 \end{verbatim}
70 The \Ref{CREATE_PROCESS} macro actually defines the #main()# function
71 and creates an instance of Hello. This assures that everything is
72 initialised in the correct order. C++ does initialisation of global
73 statics badly (and destruction is even worse), so try to put
74 everything into your PProcess descedent rather than globals.
76 A GUI application is very similar but is descended off
77 \Ref{PApplication} rather than \Ref{PProcess}, and would create a
78 window as a descendent off the \Ref{PMainWindow} class.
