电信网管系统中，设备状态信息的实时展示非常重要，通常会挂载一堆图标来展示状态或告警信息，图标的信息量有限，有时需要更详细的面板，甚至以图表的形式展现，本文将结合最近客户提到的需求，使用 Qunee1.6 beta版本，实现拓扑图中设备信息的实时显示。
此外，还需要将 CPU 的数值与柱状图绑定，这里用到Q.Element#addUI(ui, bindingProperties)函数，在第二个参数中设定数据绑定，如果有多个属性需要绑定可以使用数组，下面的例子将cpuBar的 data 属性与 node 的cpu属性进行了绑定，绑定后就可以通过node.set("cpu", 0.45)这样的方式对 ui 进行属性设置了
var cpu = new Q.LabelUI("CPU");
cpu.position = {x: 27, y: 47};
cpu.anchorPosition = Q.Position.RIGHT_MIDDLE;
var cpuBar = new BarUI();
cpuBar.position = {x: 30, y: 47};
cpuBar.anchorPosition = Q.Position.LEFT_MIDDLE;
node.addUI(cpu);
node.addUI(cpuBar, {
property : "cpu",
propertyType : Q.Consts.PROPERTY_TYPE_CLIENT,
bindingProperty : "data"
});
node.set("cpu", 0.56); 实际使用中我们对函数做了封装，看起来会不太一样，下面是节点展开时的 ui 分布设置，主体为一个140 X 120的圆角矩形，上面分布多个文本，图标和柱状图
var w = 140, h = 120, r = 10;
var shape = Q.Shapes.getRect(-w/2, -h/2, w, h, r, r);
this.image = shape;
var gradient = new Q.Gradient(Q.Consts.GRADIENT_TYPE_LINEAR, ["#F4F4F4", "#FFFFFF", "#DFDFDF", "#E9E9E9"]);
gradient.angle = Math.PI / 2;
this.setStyle(Q.Styles.SHAPE_FILL_GRADIENT, gradient);
this.setStyle(Q.Styles.SHAPE_STROKE, 0);
this.setStyle(Q.Styles.SHAPE_OUTLINE, 1);
this.setStyle(Q.Styles.SHAPE_OUTLINE_STYLE, "#C9C9C9");
this.setStyle(Q.Styles.LAYOUT_BY_PATH, false);
function addUIAt(node, ui, x, y, bindingProperty, value){
ui.syncSelection = false;
ui.zIndex = 1;
ui.position = {x: x, y: y};
ui.anchorPosition = Q.Position.LEFT_TOP;
ui.fontSize = 10;
var binding;
if(bindingProperty){
binding = {
property : bindingProperty,
propertyType : Q.Consts.PROPERTY_TYPE_CLIENT,
bindingProperty : "data"
}
}
node.addUI(ui, binding);
return ui;
}
var icon = new Q.ImageUI(image);
icon.size = this.iconSize;
addUIAt(this, icon, 15, 12, "icon").anchorPosition = Q.Position.CENTER_MIDDLE;
addUIAt(this, new Q.LabelUI(name), 30, 5);
addUIAt(this, new Q.LabelUI(id), 30, 22).color = "#D00";
addUIAt(this, new Q.LabelUI("CPU"), 27, 47).anchorPosition = Q.Position.RIGHT_MIDDLE;
addUIAt(this, new Q.LabelUI("MEM"), 27, 65).anchorPosition = Q.Position.RIGHT_MIDDLE;
addUIAt(this, new BarUI(), 30, 47, "cpu").anchorPosition = Q.Position.LEFT_MIDDLE;
addUIAt(this, new BarUI(), 30, 65, "memory").anchorPosition = Q.Position.LEFT_MIDDLE;
addUIAt(this, new Q.LabelUI("Incoming:"), 71, 90).anchorPosition = Q.Position.RIGHT_MIDDLE;
addUIAt(this, new Q.LabelUI("Outgoing:"), 71, 106).anchorPosition = Q.Position.RIGHT_MIDDLE;
var ui = addUIAt(this, new Q.LabelUI(), 75, 90, "incoming");
ui.anchorPosition = Q.Position.LEFT_MIDDLE;
ui.color = "#C20";
ui = addUIAt(this, new Q.LabelUI(), 75, 106, "outgoing");
ui.anchorPosition = Q.Position.LEFT_MIDDLE;
ui.color = "#C20";
Object.defineProperties(CustomServerNode.prototype, {
showDetail: {
get: function(){
return this._showDetail;
},
set: function(show){
if(this._showDetail == show){
return;
}
this._showDetail = show;
this.image = show ? this.shape : this.get("image");
this.name = show ? "双击合并" : (this.get("name") + "\n" + this.get("id"));
var uis = this.bindingUIs;
if(uis){
uis.forEach(function(ui){
ui.ui.visible = show;
})
this.invalidate();
}
}
}

graph.ondblclick = function(evt){
var element = evt.getData();
