Listbox

Listbox

• Demonstration: Listbox
• Java API: Listbox
• JavaScript API: Listbox

Employment/Purpose

Components: listbox, listitem, listcell, listhead and listheader.

A list box is used to display a number of items in a list. The user may select an item from the list.

Autopaging

When using the paging mold and vflex, you could also turn on autopaging (Listbox.setAutopaging(boolean)) such that the page size will be adjusted automatically based on the available space.

Example

 <window title="listbox demo" border="normal">
         <listbox id="box" width="250px">
             <listhead sizable="true">
                 <listheader label="name" sort="auto"/>
                 <listheader label="gender" sort="auto"/>
             </listhead>
             <listitem>
                 <listcell label="Mary"/>
                 <listcell label="FEMALE"/>
             </listitem>
             <listitem>
                 <listcell label="John"/>
                 <listcell label="MALE"/>
             </listitem>
             <listitem>
                 <listcell label="Jane"/>
                 <listcell label="FEMALE"/>
             </listitem>
             <listitem>
                 <listcell label="Henry"/>
                 <listcell label="MALE"/>
             </listitem>
             <listfoot >
                 <listfooter><label value="This is footer1"/></listfooter>
                 <listfooter><label value="This is footer2"/></listfooter>
             </listfoot>
         </listbox>        
 </window>

Listbox has two molds: default and select. If the select mold is used, the HTML's SELECT tag is generated instead.

<zk>
	<zscript><![CDATA[
		ListModelList lm = new ListModelList(Arrays.asList(new String[] { "David",
				"Thomas", "Steven" }));
	]]></zscript>
	
	<listbox width="300px" model="${lm}" onAfterRender="self.setSelectedIndex(2)"/>
</zk>
