Dynatree and qtip2 — No (hover) events on first su

问题:

I have a custom qtip that I want to show when you hover the mouse over a node in my Dynatree.

The problem I'm having is that I do not seem to be getting any subnode hover events on the first child of a parent.

I'm creating children like this:

var tipKey = uuid();
var childNode = parent.addChild({
            title: field.Description,
            isFolder: false,
            icon: icon,
            key: tipKey,
            addClass: tipKey,
        });
        $("." + tipKey).qtip({
            content: {
                text: '   ',
                title: {
                    text: '   '
                }
            },
            style: {
                classes: 'ui-tooltip-shadow ui-tooltip-yellow'
            },
            events: {
                show: function (event, api) {
                    var node = $.ui.dynatree.getNode($(api.elements.target));
                    var field = _workingFieldList[node.data.key];
                    //code to set qtip content omitted.
                }
            }
        });

All the tips appear just fine except the 1st child of every parent. This is either a bug, or, some strange issue I'm not seeing. If I add a handler for $('#tree a').hover(), I do get the events on every mousein/out; I tried to use that to show the qtip, but that did not work either.

Dynatree renders nodes only when expanded for the first time, so your code may bind too early. Try to bind in the 'onCreate' callback instead.
