如何在Renderer中设置属性

ClassFactory的properties妙用

public function genAdgColumn(headerText:String,dataField:String,width:Number=100):AdvancedDataGridColumn{var col:AdvancedDataGridColumn=new AdvancedDataGridColumn();col.headerText=headerText;col.dataField=dataField;col.width=width;return col;}public function genAdgColumnGroup(headerText:String,dataField:String,children:Array,expand:Boolean=true):AdvancedDataGridColumnGroup{var group:AdvancedDataGridColumnGroup=new AdvancedDataGridColumnGroup();group.headerText=headerText;group.dataField=dataField;var cf:ClassFactory=new ClassFactory(GroupHeaderRenderer);cf.properties ={'children':children,'expand':expand};group.headerRenderer=cf;group.children=children;return group;}
