ZK Component Reference/Layouts/Hbox

Hbox

• Demonstration: Hbox
• Java API: Hbox
• JavaScript API: Box
• Style Guide: Hbox

Employment/Purpose

The hbox component is used to create a horizontally oriented box. Each component placed in the hbox will be placed horizontally in a row.

Notice that hbox and vbox are designed to provode more sophisticated layout, such as splitter, alignment and packing. If you need only the layout feature, it is suggest to use Hlayout and Vlayout instead, since the performance is much better (due to the use of HTML DIV instead of TABLE).

Example

<zk>
	<vbox>
		<button label="Button 1" />
		<button label="Button 2" />
	</vbox>
	<hbox>
		<button label="Button 3" />
		<button label="Button 4" />
	</hbox>
</zk>

Align and Pack

<zk xmlns:n="http://www.zkoss.org/2005/zk/native">
	<zscript><![CDATA[
		Map map = new LinkedHashMap();
		String[] packs = new String[]{"", "start", "center", "end"};
		String[] aligns = new String[]{"", "stretch", "start", "center", "end"};
		
		for (int i = 0; i < packs.length; i++) {
			String pack = packs[i];
			List list = new ArrayList();
			for (int j = 0; j < aligns.length; j++) {
				list.add(aligns[j]);
			}
			map.put(pack, list);
		}
		
	]]></zscript>
	<tablelayout columns="6">
		<tablechildren >
			<panel border="normal" height="100px" width="100px" 
				forEach='"align / pack", "", "stretch", "start", "center", "end"'>
				<panelchildren>
					<n:h3>${each}</n:h3>
				</panelchildren>	
			</panel>
		</tablechildren>
		<tablechildren forEach="${map}">
			<variables key="${each.key}"/> 
			<panel border="normal" height="100px" width="200px">
				<panelchildren>
					<n:h3>${key}</n:h3>
				</panelchildren>	
			</panel>
			<panel border="normal" height="100px" width="200px" forEach="${each.value}" >
				<panelchildren>
					<hbox pack="${key}" align="${each}" height="90%" width="100%">
						<button label="1" />
						<button label="2" />
						<button label="3" />
					</hbox>
				</panelchildren>	
			</panel>
		</tablechildren>
	</tablelayout>
</zk>
