如何使用图德古拉在多个节点上进行矩形选择？ [英] How can I make rectangle selection on multiple nodes with graph dracula?

问题描述

我正在研究一些图形可视化，并且正在使用JavaScript库图德古拉。现在，在这个库中，当我想要移动一个节点时，我必须单击要移动的节点并将其移动到所需的位置（通过拖放操作）。但是，我想要做的是选择更多节点并移动它们。我无法弄清楚如何做到这一点，因为我在JavaScript编程方面经验不足。所以，我的问题是：

1. 如何选择多个矩形选择节点并移动
   它们？


2. 如何选择多个节点，例如Ctrl +左键单击并选择更多节点，然后移动它们？

Dracula's 图形渲染都是由 RaphaelJS 。在这种情况下，事情对你来说可能会更容易一些。看来其他人已经问过如何移动RaphaelJS中的元素。

I am working on some graph visualizations, and I am using the JavaScript library graph Dracula. Now, with this library, when I want to move a node I have to click the node I want to move and move it on the desired place (with drag and drop). But, what I want to do is to select more nodes and move all of them. I can't figure out how to do this, since I am not so experienced in JavaScript programming. So, my question is:

1. How can I select multiple nodes with rectangle selection and move them?
2. How can I select multiple nodes with, say, Ctrl + left click and select more nodes and then move them?

解决方案

By the looks of things, almost all of Dracula's graph rendering is really managed by RaphaelJS.

In which case, things may be quite a bit easier for you. It seems other people have asked how to move elements in RaphaelJS.
