Translating the strings in a glade file is really easy: If gettext is available and loaded and the textdomain is set, it automatically looks for translations - you just have to provide the translated .mo file in the right directory.
Here is the example application, but with glade:
例 3.6. Basic example with glade
<?php
if( !extension_loaded('gtk')) {
dl( 'php_gtk.' . PHP_SHLIB_SUFFIX);
}
putenv( "LANG=" . 'de_DE'); //required on windows, because setlocale doesn't work
setlocale( LC_ALL, 'de_DE');
if( !function_exists( 'gettext')) {
//gettext not automatically loaded
if( !@dl( 'php_gettext.' . PHP_SHLIB_SUFFIX)) {
die( 'gettext extension is not available!');
}
}
bindtextdomain( 'testapp', dirname( __FILE__) . '/locale');
textdomain( 'testapp');
$glade =& new GladeXML( dirname( __FILE__) . "/example-tutorial-translation.glade");
$window = $glade->get_widget( 'window');
$button = $glade->get_widget( 'button');
$window->connect_object('destroy', array('gtk', 'main_quit'));
$button->connect_object( 'clicked', array( 'gtk', 'main_quit'));
gtk::main();
?>

Just start the script, and you will see a translated application as the string contents are already in testapp.mo.
It can be quite boring to collect all the strings which shall be translated in a .glade file. Glade has the option "save translatable strings" which creates a file containing all the strings from a glade file - it's easy to convert them to a .po file.
