Create a customized Node class with clickNode event handler

[amd.lin01]

Hi all,

I would like to create a node. If I click or select the node, there will be a message in the console.

Here are my codes.

nx.define('MyExtendNode', nx.graphic.Topology.Node, {
    view: function(view) {
         view.content[2].events.clickNode = this._nodeClick;
         return view;
    },
    methods: {
        init: function(options) {
            this.inherited(options);
        },
        dispose: function() {
            this.inherited();
        },
        _nodeClick: function(sender, event){
            console.log('node clicked')
        }
    }
});

But there is no message in console.

How could I create a customized Node class?

Hi Tzuche,

About your customized node class, you should do two small modification.

1. view.content[2].events.clickNode should be view.content[2].events.click

2. Because NeXt view engine will parse the view json. So you should follow the syntax of view definition. like:

view.content[2].events.click = "{#_nodeClick}"

I am thinking we should add your syntax support too. Will update that sooner.

I made an example for your reference.
