Component Properties

With component definitions, we could specify the initial values for the properties, attributes and annotations of a component.

Properties

Depending on the requirement, you could change the initial value of a property for a particular ZUML document, or for the whole application.

Page-wide Initialization

Suppose we want to assign normal to the border property (Window.setBorder(String)) of all windows in a ZUML document, then we could use the component directive as follows.

<?component name="window" extends="window" border="normal"?>
<window title="Border"/>

Application-wid Initialization

If you prefer to have the same initial value for all ZUML documents, you could specify it in a language addon. For example, we could prepare a file called WEB-INF/lang-addon.xml with the following content:

<language-addon>
	<component>
		<component-name>window</component-name>
		<extends>window</extends>
		<property>
			<property-name>border</property-name>
			<property-value>normal</property-value>
		</property>
	</component>
</language-addon>

Then, we could specify this file by adding the following content to WEB-INF/zk.xml:

	<language-config>
		<addon-uri>/WEB-INF/lang-addon.xml</addon-uri>
	</language-config>

For more information, please refer to ZK Configuration Reference.

Attributes

Depending on the requirement, you could change the initial value of an attribute for a particular ZUML document, or for the whole application.
