      exportPDF.setStyle("icon",Asset.ICON_FILE_PDF16);

      exportPDF.toolTip ="导出PDF";

      exportPDF.addEventListener(MouseEvent.CLICK,OnExportPDF);

      ReportViewer.Instance.CustomToolBar.addChild(exportPDF);

}

//处理导出PDF代码

privatefunctionOnExportPDF(e:MouseEvent):void

{

      trace("导出PDF");

      //生成页面

      varpages:Array = myreport.ReportEngine.GeneratePages(

             ReportViewer.Instance.Setting,

             ReportViewer.Instance.TableData,

             ReportViewer.Instance.ParameterData);

      

      //生成PDF

      varpdf:PDF = new PDF();

      for each(varpage:displayObjectin pages)

      {

             pdf.addPage();

             pdf.addImage(page,new Resize(

                    org.alivepdf.layout.Mode.RESIZE_PAGE,

                    org.alivepdf.layout.Position.LEFT));

      }

      var bytes:*=pdf.save(org.alivepdf.saving.Method.LOCAL);

      varfile:FileReference =newFileReference();

      //保存到本地，该方法要Flash player 10以上

      file.save(bytes,"Export1.pdf");

}
