TextInput 作为 DataGrid 中的 ItemRenderer：滚动问题

发布于 2024-10-05 07:53:41 字数 788 浏览 0 评论 0原文

我使用 textInput 作为数据网格的所有列的 ItemRenderer。我需要将第一行的可编辑性设置为 false。我在 itemRenderer 的创建完成时执行此操作。还尝试覆盖 upDateDislayList。它对于第一行工作正常。但其他一些行也将其可编辑性更改为 false。此外，在滚动时，许多行的可编辑性也发生了更改。请帮忙。

 覆盖公共函数集 data(value:Object):void
    { 
        super.data = 值； 
      if(listData.owner.name == "headCountGrid")
      {
      if(数据!= null && qbpHttpServ.rowDataHcGridArr != null)
          { 
             if(data["column1Data"] == qbpHttpServ.rowDataHcGridArr[0]["column1Data"])
          {
          this.editable = false;
          }
          }
     }
    }
    覆盖受保护的函数 updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void{
     super.updateDisplayList(unscaledWidth,unscaledHeight);
     var g:图形=图形；
     g.clear();
    }

I use textInput as ItemRenderer for all columns of a datagrid.I need to set editability of first row as false.I did it on creationComplete of the itemRenderer.Also tried overriding upDateDislayList.
It works fine for the first row.But some other rows also get their editability changed to false.Also on scroll many rows get their editability changed.Please help.

  override public function set data(value:Object):void
    { 
        super.data = value; 
      if(listData.owner.name == "headCountGrid")
      {
      if(data != null && qbpHttpServ.rowDataHcGridArr != null)
          { 
             if(data["column1Data"] == qbpHttpServ.rowDataHcGridArr[0]["column1Data"])
          {
          this.editable = false;
          }
          }
     }
    }
    override protected function updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void{
     super.updateDisplayList(unscaledWidth,unscaledHeight);
     var g:Graphics = graphics;
     g.clear();
    }
