ZK BorderLayout 取消预览(Preview)功能

关键在於使用ZK 5 的Client Event

<?page title="new page title" contentType="text/html;charset=UTF-8"?>
<zk xmlns:w="http://www.zkoss.org/2005/zk/client">
	<borderlayout width="400px" height="400px" style="border:1px solid gray;">
		<west title="West" size="25%"
			splittable="true" collapsible="true"
			w:doClick_="function (evt) { if (evt.domTarget != this.$n('colled')) this.$doClick_(evt);}">
			<div >
				<label value="25%"  />
			</div>
		</west>
		<center border="none" flex="true">
			<div >
				<label value="哈罗"  />
			</div>
		</center>
	</borderlayout>
</zk>
