ZK Component Development Essentials/Creating the Configuration Files/The language-addon

The language-addon contains a description of the relation between the component and widget referred to as the component definition. The path of the file must be /metainfo/zk/lang-addon.xml and be located in the Java class path.

<language-addon>
	<addon-name>simplelabel</addon-name>
	<language-name>xul/html</language-name>
 
	<component>
		<component-name>simplelabel</component-name>
		<component-class>com.foo.SimpleLabel</component-class>
		<widget-class>com.foo.SimpleLabel</widget-class>
		<mold>
			<mold-name>default</mold-name>
			<mold-uri>mold/simple-label.js</mold-uri>
		</mold>
	</component>
</language-addon>

The table below describes the elements used within the above XML and their descriptions.

Name	Description
addon-name	A unique name for this addon
language-name	The language name that this addon belongs to (for instance, xul/html or zhtml)
component-name	A unique name of the component in the language of this addon
component-class	The name of the component class (Java class)
widget-class	The name of the widget class (JavaScript class)
mold	A mold definition (optional)
mold-name	The name of the mold. The default mold is named default.
mold-uri	The URI of the mold

A component may have multiple molds which may or may not have different widget classes. To handle this you may specify the <widget-class> inside <mold>. You can specify more than one mold.

After creating the component descriptor language-addon we need to create the widget package descriptor.
