ArcGIS Flex Viewer 实现图层ToolTip和单击弹框

首先添加一个widget：

<?xml version="1.0" encoding="utf-8"?>
<viewer:BaseWidget xmlns:fx="http://ns.adobe.com/mxml/2009"
                   xmlns:s="library://ns.adobe.com/flex/spark"
                   xmlns:mx="library://ns.adobe.com/flex/mx"
                   xmlns:viewer="com.esri.viewer.*"
				   xmlns:esri="http://www.esri.com/2008/ags"
                   layout="absolute"
				   width="100%" height="100%"
                   widgetConfigLoaded="basewidget_widgetConfigLoadedHandler(event)">

	<fx:Style>
		@namespace esri "http://www.esri.com/2008/ags";
		@namespace mx "library://ns.adobe.com/flex/mx";
		
		esri|InfoWindow
		{
			backgroundAlpha: 0.8;
			backgroundColor: #353930;
			borderThickness: 0;
			infoPlacement: top;
			shadowAlpha: 0.5;
			shadowDistance: 10;
			upperRightRadius: 0;
		}
		mx|ToolTip
		{
			backgroundColor: #E4342A;
			color: #FFFFFF;
			fontFamily: "Helvetica";
			fontSize: 14;
		}
	</fx:Style>
    <fx:Script>
        <![CDATA[

			}
