Flex 4 随记

1. Flex多状态事件

	private function state1Handler(event:MouseEvent):void
	{
		this.currentState = "s2";
		Alert.show("1","标题");
	}
	
	private function state2Handler(event:MouseEvent):void
	{
		this.currentState = "s1";
		Alert.show("2","标题");
	}

	<s:states>
		<s:State name="s1"/>
		<s:State name="s2"/>
	</s:states>
	<s:Button click="state1Handler(event)" click.s2="state2Handler(event)"/>
	<s:Button click.s1="state1Handler(event)" click.s2="state2Handler(event)"/>

click=""监听一个Click事件，Flex4之后提供可以通过 click.状态  来根据不同状态添加事件监听
