Flex中AdvancedDataGrid上的TreeColumn的ItemRenderer

以下是我为实现这一目标所做的工作:

创建一个扩展AdvancedDataGridGroupItemRenderer的类

在新类中重写updateDisplayList并执行您需要执行的操作

将新类分配给AdvancedDataGrid的groupItemRenderer属性

这是你的新课程的样子

public class CustomGroupRenderer extends AdvancedDataGridGroupItemRenderer
{
    override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
    {
        super.updateDisplayList(unscaledWidth, unscaledHeight);

        var listData:AdvancedDataGridListData = listData as AdvancedDataGridListData;
        var advancedDataGrid:AdvancedDataGridDataGrid = listData.owner as AdvancedDataGrid;

        var cellBackgroundColor:uint = 0xFF0000;

        var g:Graphics = graphics;
        g.clear();

        if (!advancedDataGrid.isItemSelected(data) && !advancedDataGrid.isItemHighlighted(data))
        {
            g.beginFill(cellBackgroundColor);
            g.drawRect(0, 0, unscaledWidth, unscaledHeight);
            g.endFill();
        }
    }
}

然后将此类分配给AdvancedDataGrid的groupItemRenderer属性:

或者,在ActionScript中:

myAdvancedDataGrid.groupItemRenderer = new ClassFactory(com.whereever.CustomGroupRenderer);
