ags infoWindow 应用

1 首先如何设置 infowindow或infoWindowRenderer的边框背景色:

 

<fx:Style> @namespace esri "http://www.esri.com/2008/ags";
		esri|InfoWindowLabel
		{
			color: white;
			font-size: 20;
		}
		esri|InfoWindow
		{
			border-thickness: 0;
			background-color: green;
			font-size: 16;
			upper-left-radius: 15;
			upper-right-radius: 0;
			info-placement: top;
			info-offset-y: 20;            
		}
	 
	</fx:Style>

 效果如图:

2 点击地图 任意位置 弹出一个信息窗:

private function onMouseCLK(event:MapMouseEvent):void
{
  myMap.infoWindow.show(myMap.toMapFromStage(event.stageX, event.stageY));
//设置里面的文字:
myTextArea.text="asdfasf";
}
 
 

  设置信息泡的组件:

<esri:Map id="myMap"   mapClick="onMouseCLK(event)">
 <esri:infoWindowContent>
            <mx:TextArea id="myTextArea"
                         width="250" height="75"/>
        </esri:infoWindowContent>
</esri:Map>
 

3 点击任意一个图元,弹出信息窗:

 方式一: 最简单,直接在给图层的infoWindowRenderer 属性赋值:

<esri:GraphicsLayer > 
   <esri:infoWindowRenderer>
                <fx:Component>
                    <mx:VBox backgroundColor="0xffffff"
                             color="0x444444"
                             label="Parcel {data.PARCELID}">
                        <mx:Label text="Owner: {data.OWNERNME1}"/>
                        <mx:Label text="Address: {data.SITEADDRESS}"/>
                        <mx:Label text="Land Value: {data.LNDVALUE}"/>
                        <mx:Label text="Landuse: {data.USECD}"/>
                    </mx:VBox>
                </fx:Component>
            </esri:infoWindowRenderer>
<esri:GraphicsLayer/> 
 

 

方式二:  给graphic加 事件,在事件处理函数中弹出信息窗,所以当图元超过500时,效率很差。

<esri:GraphicsLayer id="roadLayer" graphicAdd="fLayer_graphicAddHandler" />

<!--当图层被加入图元时 触发事件-->

 

  protected function fLayer_graphicAddHandler(event:GraphicEvent):void
      {
                event.graphic.addEventListener(MouseEvent.MOUSE_CLICK, onMouseClkHandler);
     }

  pprivate function onMouseClkHandler(event:MouseEvent):void
 {
                var gr:Graphic = Graphic(event.target);
                gr.symbol = mouseOverSymbol;
                myMap.infoWindow.label = gr.attributes.NAME;
                myMap.infoWindow.closeButtonVisible = false;
                myMap.infoWindow.show(myMap.toMapFromStage(event.stageX, event.stageY));
   }
 

或者:

gra.infoWindowRenderer=new ClassFactory(weatherInfoWin);

gra.symble=....;
