为什么我不能随意的拖动整体

当我拖动整体结构时,到了边缘就不能拖动了,这是为什么

I’m sorry, but I do not understand your question.

Have you read GoJS Coordinate Systems-- Northwoods Software ?

首先很抱歉我没有表达清楚问题意思,我的结构图禁止了单个节点的拖动,但是没有禁止对整个结构图的拖动,现在的问题就是,我不能将整个结构图拖出文档边缘,似乎有什么东西挡住,不让他拖出外界

I still do not understand. Could you be more specific about what you want the user to be able to do?

And I still think reading that Introduction page about documentBounds and scrollMode might help.

很对不起,我的表达能力不是很好,但是你还是帮我解决了问题,谢谢
