Selectbox

Employment/Purpose

Selectbox is a lightweight dropdown list and it can support ListModel, Renderer, and Databinding as well. The benefit of it is not to create child widgets for each data, so the memory usage is much lower at the server.

Example

Selectbox-Example1.png

<zk>
	<zscript>
		<![CDATA[
		String[] userName = { "Tony", "Ryan", "Jumper", "Wing", "Sam" };
		ListModelList model = new ListModelList(userName);
	]]></zscript>
	<selectbox model="${model}" onSelect='alert(model.get(event.getData()));'>
		<template name="model">
			Name is ${each}
		</template>
	</selectbox>
</zk>

Databinding

Here is the example for Databinding.

<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit"?>
<zk>
	<zscript><![CDATA[
	public class MyUserBean {
		private String[] userList = { "Tony", "Ryan", "Jumper", "Wing", "Sam" };
		private int index = 0;

		public ListModelList getUserList() {
			return new ListModelList(Arrays.asList(userList));
		}

		public void setUserList() {
		}

		public void setIndex(int ind) {
			index = ind;
		}

		public int getIndex() {
			return index;
		}

		public String getCurrentName() {
			return userList[index];
		}
	}
	MyUserBean mybean = new MyUserBean();
/**   Implements ItemRenderer without using template
       org.zkoss.zul.ItemRenderer render = new org.zkoss.zul.ItemRenderer() {
		public String render(Component owner, Object data, int index) throws Exception {
			return data.toString();
		}
	};
*/
	]]></zscript>
	<div>
		Select User:
		<selectbox id="box" model="@{mybean.userList}"
			selectedIndex="@{mybean.index}">
			<template name="model">${each}</template>
		</selectbox>

	</div>
	Selected:
	<label id="val" value="@{mybean.currentName}" />
</zk>
