jointjs - 不触发单元格事件

Question

我有一份带有图表的工作文件。我已向图表中添加了多个单元格，并且正在尝试监听 cell:highlight 事件，但我从未收到它。

我正在做:

paper.on('cell:highlight', function() { ... });

其他事件似乎工作正常，例如:blank:pointerup，...

是否需要采取一些特殊措施才能使细胞事件发挥作用？

根据文档:

cell:highlight - triggered when highlight() method is called on either an element or a link. Note that this method is also called automatically when the user is reconnecting a link and the connection is valid (validateConnection() returns true) or if embeddingMode is enabled on the paper and the dragging element is above another element it could be dropped into (validateEmbedding() returns true). The handler for this event has the following signature: function(cellView,el). The handler defaults to function(cellView, el) {
V(el).addClass('highlighted') }. In other words, the 'higlighted' CSS class is added and so you can style the highlighted element in CSS. If you want to use a different method for highlighting cells, call paper.off('cell:highlight') first to unregister the default handler and then paper.on('cell:highlight', myHandler) to register your own.
