Examples of org.zkoss.zk.ui.util.Composer

• org.zkoss.zk.ui.util.Composer
  Represents a composer to initialize a component (or a component of tree) when ZK loader is composing a component. It is the controller in the MVC pattern, while the component is the view.

  To initialize a component, you can implement this interface and then specify the class or an instance of it with the apply attribute as follows.

  <window apply="my.MyComposer"/> <window apply="${a_composer}"/>

  Then, ZK loader will

  1. Invoke {@link ComposerExt#doBeforeCompose}, if the composer also implements {@link ComposerExt}.
  2. Create the component (by use of {@link org.zkoss.zk.ui.sys.UiFactory#newComponent}, which creates and initializes the component accordingly).
  3. Invokes {@link ComposerExt#doBeforeComposeChildren}, if {@link ComposerExt} is also implemented.
  4. Composes all children, if any, of this component defined in the ZUML page.
  5. Invokes {@link #doAfterCompose} after all children are, if any,composed.
  6. Posts the onCreate event if necessary.

  To intercept the lifecycle of the creation of a page, implement {@link Initiator} and specify the class with the init directive.

  Note: {@link org.zkoss.zk.ui.ext.AfterCompose} has to be implementedas part of a component, while {@link Composer} is a controller usedto initialize a component (that might or might not implement {@link org.zkoss.zk.ui.ext.AfterCompose}). @author tomyeh @since 3.0.0 @see org.zkoss.zk.ui.ext.AfterCompose @see ComposerExt @see FullComposer @see Initiator
