public interface Localizable
GWT.create(class) to
instantiate a type that directly extends or implements
Localizable invites locale-sensitive type substitution.
Type directly extends or implements
Localizable (as opposed to
Constants or
Messages) and the following code is used
to create an object from Type as follows:
Type localized = (Type)GWT.create(Type.class);then
localized will be assigned an instance of a localized
subclass, selected based on the value of the locale client
property. The choice of subclass is determined by the following naming
pattern:
If locale is... |
The substitute class for Type is... |
|---|---|
| unspecified | Type itself, or Type_ if Type
is an interface |
x |
Class Type_x if it exists, otherwise treated as if
locale were unspecified |
x_Y |
Class Type_x_Y if it exists, otherwise treated as if
locale were x |
x is a ISO language
code and Y is a two-letter ISO
country code.
locale client
property, which can be specified using either a meta tag or as part of the
query string in the host page's URL. If both are specified, the query string
takes precedence.
To specify the locale client property using a meta tag in the
host HTML, use gwt:property as follows:
<meta name="gwt:property" content="locale=x_Y">For example, the following host HTML page sets the locale to "ja_JP":
<html>
<head>
<meta name="gwt:module" content="com.google.gwt.examples.i18n.ColorNameLookupExample">
<meta name="gwt:property" content="locale=ja_JP">
</head>
<body>
<script src="gwt.js"></script>
</body>
</html>
To specify the locale client property using a query string,
specify a value for the name locale. For example,
http://www.example.org/myapp.html?locale=fr_CA
