Question

单击Datagrid项时是否可以触发Flex Piechart Item单击事件。如果是这样，任何人都可以举一些例子。

Answer 1

我会尝试在PieChart上举起一个事件，但有点不同。我会尝试将饼图逻辑封装到一个新函数

中

如果你在饼图上有这样的事件：

    private function PieChartClick(event:ItemEvent):void{
       DoPieChartClick();
    }

    private function DoPieChartClick():void{
       var selectedItem = picChart.SelectedItem;
       //do the rest of your logic
    }

    private function DataGridClick(event:ItemEvent):void{
        //do your datagrid stuff
        DoPieChartClick(); //This would be like you clicked on the pie chart.
    }

Answer 2

是的，只要点击了数据网格或任何其他元素，就可以触发itemClick事件。这里重要的是数据网格中项目的--index--应该是--index--的函数饼图中的项目。

任何图表都有一个“系列”元素，任何“系列”元素都包含“items”数组。您可以使用flex触发机制触发悬停/单击此“项目”。
