动作脚本:如何以编程方式编写DataGrid？

Question

我有这个代码,但我试图将其转换为actionscript,所以我渲染这个programaticaly但我失败了.我怎么在AS上写这个？

<mx:DataGrid  allowMultipleSelection="true" id="dg_disk" dataProvider="{people}" height="100%" width="100%" selectedIndex="0" x="50" y="50">
        <mx:columns>
            <mx:DataGridColumn dataField="name"         id="empname"     headerText="EmpName"/>
            <mx:DataGridColumn dataField="title"     id="title" headerText="Title"/>
            <mx:DataGridColumn dataField="description"         id="desc"        headerText="Description"/>
           </mx:DataGridColumn>
        </mx:columns>

    </mx:DataGrid>

Answer 1

这是我编写的程序的一部分.mSessionLogDG是DataGrid(在这种情况下,我们将动态列添加到现有的列).

private function createColumns() : void {
            var _columnArray : Array = mSessionLogDG.columns;
            var _initialOffset : uint = _columnArray.length;
            // TODO
            if ( _initialOffset > CreateCommentNamesCommand.MAX_NO_COMMENTS ) return;

            this.mOffset = _initialOffset;

            var _headerLabel : String = '';
            for ( var i : uint = 0; i < CreateCommentNamesCommand.MAX_NO_COMMENTS; i++ )
            {
                var _dataColumn : DataGridColumn = new DataGridColumn();
                _dataColumn.headerText = this.createCommentNamesCommand.labelArray[i];
                _dataColumn.setStyle( "paddingLeft", "3" );
                _dataColumn.setStyle( "textAlign", "left" );
                _dataColumn.setStyle( "customID", i );
                _dataColumn.width = 160;
                _dataColumn.labelFunction = labelFunc;                                      
                _dataColumn.sortCompareFunction = SessionDescriptionXmlVo.mCommentCompareFunctionArray[i];
                _dataColumn.itemRenderer = new ClassFactory( SessionCommentItemRenderer );
                _dataColumn.visible = false;
                _dataColumn.minWidth = 160;
                _columnArray.push( _dataColumn );                   
                mColumnArray[i] = _dataColumn;
            }

            mSessionLogDG.columns = _columnArray;               
        }
