问题 I try to implement something like a "drag and drop" for a ListView. The task is simple. I have a "side menu" where I put some objects in a list. They are all shown there.

问题 I have a spark List,its item renderer is a panel,and in the panel there are some components such as Textinput,now I want to drag and drop a panel within the List,how can I do that,could you pls show me the code,thanks. 回答1: The list in flex has a default drag and drop functionality.
