The ApplicationUpdaterUI class provides a default user
interface for the update process. This includes dialog boxes that
let the user start the process, cancel the process, and perform
other related actions.
The description element of the update descriptor
file lets you define the description of the application in multiple
languages. Use multiple text elements that define lang attributes,
as in the following:
<?xml version="1.0" encoding="utf-8"?>
<update xmlns="http://ns.adobe.com/air/framework/update/description/1.0">
<version>1.1a1</version>
<url>http://example.com/updates/sample_1.1a1.air</url>
<description>
<text xml:lang="en">English description</text>
<text xml:lang="fr">French description</text>
<text xml:lang="ro">Romanian description</text>
</description>
</update>
The update framework uses the description that best fits the
end user’s localization chain. For more information, see Defining
the update descriptor file and adding the AIR file to your web server.
Flex developers can directly add a new language to the "ApplicationUpdaterDialogs" bundle.
JavaScript developers can call the addResources() method
of the updater object. This method dynamically adds a new resource
bundle for a language. The resource bundle defines localized strings
for a language. These strings are used in various dialog box text
fields.
JavaScript developers can use the localeChain property
of the ApplicationUpdaterUI class to define the locale chain used
by the user interface. Typically, only JavaScript (HTML) developers
use this property. Flex developers can use the ResourceManager to
manage the locale chain.
For example, the following JavaScript code defines resource bundles
for Romanian and Hungarian:
appUpdater.addResources("ro_RO",
{titleCheck: "Titlu", msgCheck: "Mesaj", btnCheck: "Buton"});
appUpdater.addResources("hu", {titleCheck: "Cím", msgCheck: "Üzenet"});
var languages = ["ro", "hu"];
languages = languages.concat(air.Capabilities.languages);
var sortedLanguages = air.Localizer.sortLanguagesByPreference(languages,
air.Capabilities.language,
"en-US");
sortedLanguages.push("en-US");
appUpdater.localeChain = sortedLanguages;
For details, see the description of the addResources() method
of the ApplicationUpdaterUI class in the language reference.
