在自定义的widget中引入图表后,运行时出现TypeError
#1009错误。本人网上查找了很多资料,其中大部分都是关于Flash中的动画效果问题,与这里的问题关系型不太大。故把问题的解决方法写在这里,与人方便,与己方便。
方法一:
1.在自定义的widget中添加如下两个方法:
private function copyStyleFromParent(selector:String):void
{
var chartBaseStyle:CSSStyleDeclaration =
styleManager.getStyleDeclaration(selector);
if (!chartBaseStyle &&
styleManager.parent)
{
var parentStyle:CSSStyleDeclaration =
styleManager.parent.getStyleDeclaration(selector);
if (parentStyle)
{
styleManager.setStyleDeclaration(selector,
parentStyle, false);
}
}
}
protected function preinitializeHandler ():void
{
var styleObjects:Array =new Array();//FlexGlobals.topLevelApplication.styleManager.selectors;
styleObjects.push( "mx.charts.chartClasses.ChartBase" );
styleObjects.push( "mx.charts.chartClasses.CartesianChart" );
styleObjects.push( "mx.charts.chartClasses.PolarChart" );
styleObjects.push( "mx.charts.BarChart");
styleObjects.push( "mx.charts.ColumnChart" );
styleObjects.push( "mx.charts.LineChart");
styleObjects.push( "mx.charts.PieChart");
styleObjects.push( "mx.charts.AxisRenderer" );
styleObjects.push( ".blockCategoryAxis");
styleObjects.push( ".blockNumericAxis");
styleObjects.push( ".linedNumericAxis");
styleObjects.push( ".dashedNumericAxis");
styleObjects.push( ".dashedCategoryAxis");
styleObjects.push( ".hangingCategoryAxis");
styleObjects.push( "mx.charts.GridLines");
styleObjects.push( ".horizontalGridLines");
styleObjects.push( "mx.charts.series.BarSeries" );
styleObjects.push( "mx.charts.series.ColumnSeries" );
styleObjects.push( "mx.charts.series.LineSeries" );
styleObjects.push( "mx.charts.series.PieSeries" );
for each(var styleObj:String in styleObjects) {
copyStyleFromParent(styleObj);
}
}
2.在该自定义widget头部中添加preinitialize="preinitializeHandler ()" 。
方法二:
在自定义widget中覆盖父类的moduleFactory方法:
override
public function get moduleFactory():IFlexModuleFactory {
return
FlexGlobals.topLevelApplication.moduleFactory;
}
