Hello.Im having a problem with this, i hope u guys can help me.I have a main app called Lllayllay where i put some title windows adding them as mx component binded with some functions about arcgis map and layers.Now im trying to change the title windows to a popup because i cannot drag them.To do that i read something that i need to change those title windows objects to a mxml component, so when i tried to do that i figure out that my functions binded in the main file the new componenr (the other mxml file) cannot be used.So, how can i call functions from a mxml component that they are being used in the main file?An example is.Main app:A button with click event and a click function to do something with arcgis developTWindowComp.mxml<?xml version="1.0" encoding="utf-8"?> <mx:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300" xmlns:components="org.example.components.*"> <fx:Script> <![CDATA[ import mx.core.Application; import mx.core.FlexGlobals; import spark.components.Application; protected function exExcelMedidores_clickHandler(event:MouseEvent):void { // TODO Auto-generated method stub } ]]> </fx:Script> <fx:Declarations> <!-- Place non-visual elements (e.g., services, value objects) here --> </fx:Declarations> <s:VGroup width="100%" bottom="5" height="100%"> <s:HGroup width="100%" verticalAlign="middle"> <components:SearchBar id="searchBar" width="100%"/> <s:Button id="exExcelMedidores" click="generateXLS()" label="Exportar" width="20%" height="22" /> </s:HGroup> <s:DataGrid id="dgridEquipos" resizableColumns="true" skinClass="dataGridSkin" sortableColumns="true" contentBackgroundAlpha="1" width="100%" height="90%" visible="true" editable="false" bottom="1" click="dgridEquipos_clickHandler(event)" > <s:columns> <s:ArrayList> <s:GridColumn dataField="id_medidor" headerText="ID Equipo"></s:GridColumn> <s:GridColumn dataField="nis" headerText="NIS"></s:GridColumn> <s:GridColumn dataField="luminarias" headerText="Cant. Luminarias"></s:GridColumn> <s:GridColumn dataField="tramos_ap" headerText="Cant. Tramos"></s:GridColumn> <s:GridColumn dataField="tipo_equipo" headerText="Tipo"></s:GridColumn> </s:ArrayList> </s:columns> </s:DataGrid> </s:VGroup> </mx:TitleWindow>The generateXLS function and the dgridEquipos_clickHandler(event) i have them in the main app and i cannot put them out of the main file.So how can i access them?Thx in advice!
