NAME

6       Wx - interface to the wxWidgets cross-platform GUI toolkit
7

SYNOPSIS

9           use Wx;
10
11           my $app = Wx::SimpleApp->new;
12           my $frame = Wx::Frame->new( undef, -1, 'Hello, world!' );
13
14           $frame->Show;
15           $app->MainLoop;
16

DESCRIPTION

18       The Wx module is a wrapper for the wxWidgets (formerly known as
19       wxWindows) GUI toolkit.
20
21       This module comes with extensive documentation in HTML format; you can
22       download it from http://wxperl.sourceforge.net/
23

INSTALLATION

25       Please see docs/INSTALL.pod in source package.
26

Runtime Assertions

28       For wxWidgets 2.9.3 and greater, Wx can switch runtime assertions on
29       and off. In wxWidgets 2.9.x and above, there are three levels of
30       debuging
31
32       0 - No debug assertions 1 - Low cost debug assertions 2 - All debug
33       assertions
34
35       If you used Alien::wxWidgets 0.61 or greater to build your wxWidgets,
36       then the libraries will be built using debug level 1. If you specified
37       --wxWidgets-debug for a debug build, then debug level 2 will have been
38       used.
39
40       By default in Wx, debug assertions are switched off. However you may
41       switch assertions on by using
42
43        Wx::EnableDefaultAssertHandler();
44
45       you can switch assertions off again by using
46
47        Wx::DisableAssertHandler();
48
49       You may also set en enviroment variable to cause all invocations of Wx
50       to call Wx::EnableDefaultAssertHandler().
51
52        export WXPERL_OPTIONS=ENABLE_DEFAULT_ASSERT_HANDLER
53
54       This may be useful during tests.
55
56       The enviroment setting WXPERL_OPTIONS can contain multiple options.
57       Options are checked for using a simple regex match.  So
58
59        export WXPERL_OPTIONS="ENABLE_DEFAULT_ASSERT_HANDLER SOME_OTHER_SETTING"
60
61       would evaluate as ENABLE_DEFAULT_ASSERT_HANDLER being set.
62
63       If you want to handle assert failures yourself you can override
64       wxApp::OnAssertFailure in your Wx::App derived class.
65
66         sub OnAssertFailure {
67           my ( $self, $file, $line, $function, $condition, $msg ) = @_;
68           ......
69         }
70
71       For wxWidgets 2.8.x, the assert methods have no effect. You may however
72       still usefully override wxApp::OnAssertFailure in a debug build.
73

Running on Mac OSX

75       From version 0.98 wxPerl no longer needs to use the special startup
76       executable 'wxperl' to run scripts on the Mac. The ordinary perl
77       interpreter now works without problems. This is because wxPerl now
78       contains code that brings the running application to the front and
79       gives it the focus.
80
81       In a syntax checking editor you may prevent Wx code from being given
82       focus as the front process by setting an environment variable
83
84        export WXPERL_OPTIONS=NO_MAC_SETFRONTPROCESS
85
86       or
87
88        $ENV{WXPERL_OPTIONS} = 'NO_MAC_SETFRONTPROCESS';
89
90       The enviroment setting WXPERL_OPTIONS can contain multiple options.
91       Options are checked for using a simple regex match.  So
92
93        export WXPERL_OPTIONS="NO_MAC_SETFRONTPROCESS SOME_OTHER_SETTING"
94
95       would evaluate as NO_MAC_SETFRONTPROCESS being set.
96
97       The code that makes the SetFrontProcess call is in Wx::Mini as
98
99        Wx::MacSetFrontProcess();
100
101       so it is also straightforward to override this method if you wish.
102
103       Finally, any code can force the running application to become the front
104       process regardless of environment settings by calling the xs method
105       directly. (Note the underscore in the method name).
106
107        Wx::_MacSetFrontProcess();
108

Locale Behaviour

110       Beginning with 2.9.0 wxWidgets sets the application locale to the
111       current system locale. Formally in wxWidgets 2.8.x, the locale by
112       default was 'C'.
113
114       A problem arises because in addition to loading gettext translation
115       files, this affects other C calls like printf, sprintf,...
116
117       Perl makes calls to these functions when formatting numbers.  Number
118       formatting always uses underlying C library functions.  The statements
119       'use locale', or 'no locale' make no difference here.
120
121       So, if your locale is 'de' then when Wx starts, the C library locale
122       gets set accordingly.
123
124         use Wx;
125         print 8.3
126
127       will output 8,3 to the terminal. Formatting uses ',' as the fractional
128       separator.
129
130       This, whilst possibly correct, isn't what most users will be expecting.
131
132       If you want to set the locale to the system default you can do so
133       explicitly.
134
135         $app->{locale} = Wx::Locale->new( &Wx::wxLANGUAGE_DEFAULT );
136
137       You can then also reset just the locale for number formatting to 'C' if
138       that is what you require
139
140         use POSIX qw( setlocale LC_NUMERIC );
141
142         setlocale( LC_NUMERIC, C );
143
144       This code applies equally regardless of which wxWidgets version is
145       being used.

Windows XP look

148       For standalone (packed using PAR, Perl2Exe, Perl2App, ...)
149       applications to get Windows XP look, a file named "App.exe.manifest"
150       (assuming the program is named "App.exe") and containing the text below
151       must either be placed in the same directory as the executable file or
152       compiled into the file itself. The module Win32::Exe can place a
153       manifest in an executable file
154
155         <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
156         <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
157           <assemblyIdentity version="1.0.0.0" type="win32" name="Super.wxPerl.Application" />
