垂直布局与Button

	<viewer:WidgetTemplate id="test_02" width="300" height="200">
		<s:Group>
			<s:layout>
				<s:VerticalLayout/>
			</s:layout>

			<s:Button label="1"/>
			<s:Button label="2"/>
			<s:Button label="3"/>
		</s:Group>
	</viewer:WidgetTemplate>

<s:Button label="1"/><!-- Button大写表示Button是实例，label小写表示label是属性 -->
<s:Button>
    <s:label>3</s:label>
</s:Button><!-- 与上面的写法等价 -->
