Wx(3) User Contributed Perl Documentation Wx(3)NAMEWx - 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
debuging
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 en enviroment 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 enviroment 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 enviroment 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();
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"?>
