afterCompose
public void afterCompose()
Creates the distributed children after apply dynamic propertiesIf a shadow element is created by ZK loader, this method is invoked automatically. Developers rarely need to invoke this method.
Default: it invokes
compose(org.zkoss.zk.ui.Component)
to compose the shadow element.The method will invoke the following methods in order.
- Check if
isEffective()
to be true. - If true, invokes
compose(org.zkoss.zk.ui.Component)
method to create the distributed children, otherwise, nothing happened.
Instead of overriding this method, it is suggested to override
compose(org.zkoss.zk.ui.Component)

(rather thanafterCompose()
).- Specified by:

Returns whether the shadow element is effective
-
compose
protected abstract void compose(Component host)
