Class Apply
- All Implemented Interfaces:
Serializable,Cloneable,org.zkoss.zk.ui.Component,org.zkoss.zk.ui.ext.AfterCompose,org.zkoss.zk.ui.ext.DynamicPropertied,org.zkoss.zk.ui.ext.Scope,org.zkoss.zk.ui.ShadowElement,org.zkoss.zk.ui.ShadowElementCtrl,org.zkoss.zk.ui.sys.ComponentCtrl
Passing Parameters
There are two ways to pass parameters to the apply shadow:
First, you can use setDynamicProperty(java.lang.String, java.lang.Object), or, in ZUL,
<apply templateURI="/WEB-INF/mypage" arg="something"/>
Second, you can use the query string:
<apply templateURI="/WEB-INF/mypage?arg=something"/>
With the query string, you can pass only the String values.
and the parameter can be accessed by Execution.getArg()
Or, you can access it with the arg variable in EL expressions.

Method Details
-
getTemplate
Returns the template nameDefault: empty string
-
setTemplate
Sets the template name to apply.One cannot set both template and template URI in the same time.
Notice that, the template enclosed with <apply> tag will be created only when both template and template URI are not set.
-
setTemplateURI
Sets the template uri.If templateURI is changed, the whole shadow is recreated. One cannot set both template and template URI in the same time.
Notice that, the template enclosed with <apply> tag will be created only when both template and template URI are not set.
- Parameters:
templateURI- the template URI. If null or empty, nothing is applied. You can specify the template URI with the query string and they will become a map of parameters that is accessible by the arg variable in EL, or byExecution.getArg(). For example, if "/a.zul?b=c" is specified, you can access the parameter with ${arg.b} in a.zul.- See Also:
