从链接隐藏默认悬停CSS

Question

I am using following code to add links to the graph:

var ln = new joint.dia.Link({
    source: { id: rect.id }, target: { id: curr_selected.id },
     attrs: { '.marker-source': { d: 'M 10 0 L 0 5 L 10 10 z' } }
});

Now when I added this link to graph.A cross symbol for delete operation comes by default on hovering the link but I do not want it .I need a simple arrow which can not be deleted by anyone from the graph.

You can just set the following in your CSS:

.link-tools {
    display: none;
}
