NAME

       Wx - interface to the wxWidgets cross-platform GUI toolkit

SYNOPSIS

           use Wx;

           my $app = Wx::SimpleApp->new;
           my $frame = Wx::Frame->new( undef, -1, 'Hello, world!' );

           $frame->Show;
           $app->MainLoop;

DESCRIPTION

       The Wx module is a wrapper for the wxWidgets (formerly known as wxWindows) GUI toolkit.

       This module comes with extensive documentation in HTML format; you can download it from
       http://wxperl.sourceforge.net/

INSTALLATION

       Please see docs/INSTALL.pod in source package.

Runtime Assertions

       For wxWidgets 2.9.3 and greater, Wx can switch runtime assertions on and off. In wxWidgets
       2.9.x and above, there are three levels of debugging

       0 - No debug assertions 1 - Low cost debug assertions 2 - All debug assertions

       If you used Alien::wxWidgets 0.61 or greater to build your wxWidgets, then the libraries
       will be built using debug level 1. If you specified --wxWidgets-debug for a debug build,
       then debug level 2 will have been used.

       By default in Wx, debug assertions are switched off. However you may switch assertions on
       by using

        Wx::EnableDefaultAssertHandler();

       you can switch assertions off again by using

        Wx::DisableAssertHandler();

       You may also set an environment variable to cause all invocations of Wx to call
       Wx::EnableDefaultAssertHandler().

        export WXPERL_OPTIONS=ENABLE_DEFAULT_ASSERT_HANDLER

       This may be useful during tests.

       The environment setting WXPERL_OPTIONS can contain multiple options. Options are checked
       for using a simple regex match.  So

        export WXPERL_OPTIONS="ENABLE_DEFAULT_ASSERT_HANDLER SOME_OTHER_SETTING"

       would evaluate as ENABLE_DEFAULT_ASSERT_HANDLER being set.

       If you want to handle assert failures yourself you can override wxApp::OnAssertFailure in
       your Wx::App derived class.

         sub OnAssertFailure {
           my ( $self, $file, $line, $function, $condition, $msg ) = @_;
           ......
         }

       For wxWidgets 2.8.x, the assert methods have no effect. You may however still usefully
       override wxApp::OnAssertFailure in a debug build.

Running on Mac OSX

       From version 0.98 wxPerl no longer needs to use the special startup executable 'wxperl' to
       run scripts on the Mac. The ordinary perl interpreter now works without problems. This is
       because wxPerl now contains code that brings the running application to the front and
       gives it the focus.

       In a syntax checking editor you may prevent Wx code from being given focus as the front
       process by setting an environment variable

        export WXPERL_OPTIONS=NO_MAC_SETFRONTPROCESS

       or

        $ENV{WXPERL_OPTIONS} = 'NO_MAC_SETFRONTPROCESS';

       The environment setting WXPERL_OPTIONS can contain multiple options. Options are checked
       for using a simple regex match.  So

        export WXPERL_OPTIONS="NO_MAC_SETFRONTPROCESS SOME_OTHER_SETTING"

       would evaluate as NO_MAC_SETFRONTPROCESS being set.

       The code that makes the SetFrontProcess call is in Wx::Mini as

        Wx::MacSetFrontProcess();

       so it is also straightforward to override this method if you wish.

       Finally, any code can force the running application to become the front process regardless
       of environment settings by calling the xs method directly. (Note the underscore in the
       method name).

        Wx::_MacSetFrontProcess();

Locale Behaviour

       Beginning with 2.9.0 wxWidgets sets the application locale to the current system locale.
       Formally in wxWidgets 2.8.x, the locale by default was 'C'.

       A problem arises because in addition to loading gettext translation files, this affects
       other C calls like printf, sprintf,...

       Perl makes calls to these functions when formatting numbers.  Number formatting always
       uses underlying C library functions.  The statements 'use locale', or 'no locale' make no
       difference here.

       So, if your locale is 'de' then when Wx starts, the C library locale gets set accordingly.

         use Wx;
         print 8.3

       will output 8,3 to the terminal. Formatting uses ',' as the fractional separator.

       This, whilst possibly correct, isn't what most users will be expecting.

       If you want to set the locale to the system default you can do so explicitly.

         $app->{locale} = Wx::Locale->new( &Wx::wxLANGUAGE_DEFAULT );

       You can then also reset just the locale for number formatting to 'C' if that is what you
       require

         use POSIX qw( setlocale LC_NUMERIC );

         setlocale( LC_NUMERIC, C );

       This code applies equally regardless of which wxWidgets version is being used.

Windows XP look

       For standalone (packed using PAR, Perl2Exe, Perl2App, ...)  applications to get Windows XP
       look, a file named "App.exe.manifest" (assuming the program is named "App.exe") and
       containing the text below must either be placed in the same directory as the executable
       file or compiled into the file itself. The module Win32::Exe can place a manifest in an
       executable file

         <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
         <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
           <assemblyIdentity version="1.0.0.0" type="win32" name="Super.wxPerl.Application" />
