推荐答案

在Windows应用程序中，您可以实现处理OwnerDraw或DrawSubItem事件。如果您更改子项的任何值，它将触发DrawSubItem事件，并且在该事件上您可以绘制进度。





你可以参考以下文章了解更多详情;

In windows application you could achieve that handling OwnerDraw or DrawSubItem events. If you change any value of the subitem, it will fire the DrawSubItem event and on that event you could draw the progress.


You could refer to following article for more details;
