Flex: PieChart LabelFunction

Categories: Flex; Tagged with: Chart • Flex • Flex Chart • PieChart; @ March 4th, 2010 14:54

使用labelFunction 直接显示PieChart的信息, 如下代码定义一个PieChart:

其labelFunction:

		/** 过期分布PieChart的LabelFunction.  */
		protected static function labelFunForChartExpDEtail(item:Object, field:String, index:Number, percentValue:Number):String {
			var percentString:String = percentValue.toString().substr(0, 5);
			return UserQualStatistics.getTypeLabel(item.type) + ":" + "\n" + RM.getString(BUNDLE_DASHBOARD, "info.total") + ":" + item.total + "(" + percentString + "%)";
		}

效果:

			var curObj:Object = hd.item;
			var curSeries:BarSeries = BarSeries(hd.chartItem.element); // 获得当前的BarSeries
			return curObj.qual + "-" + curSeries.displayName + "\n" + uqStatistics.getUQAs(curSeries.xField, curObj.qualObj).length + RM.getString(BUNDLE_DASHBOARD, "label.piece");
		}

Flex: DataGrid使用ListEvent.ITEM_DOUBLE_CLICK监听双击事件

Categories: Flex; Tagged with: ActionScript • DataGrid • DoubleClicked • Flex • ListEvent • MouseEvent; @ January 31st, 2010 16:48

之前没怎么注意, 一直用MouseEvent.DOUBLE_CLICK来监听DataGrid的双击事件. 但这样会造成即使在空行双击也会激发响应.

		datagridClasses.doubleClickEnabled = true;
		datagridClasses.addEventListener(MouseEvent.DOUBLE_CLICK, onDGDoubleClicked);

正确方法应该使用ListEvent.ITEM_DOUBLE_CLICK监听项目双击事件.

		datagridClasses.addEventListener(ListEvent.ITEM_DOUBLE_CLICK, onDGDoubleClicked);
