客户提到设备面板的需求，qunee并没有Equipment这样的图元，但借助父子关系和跟随关系设置，可以实现类似功能，并完成下面的例子

示例代码

代码非常简单，这里直接列出

var graph;

function init(){

graph = new Q.Graph('canvas');

graph.originAtCenter = false;

graph.translate(20, 20);

var rack = createEquipment("", 4, 1, "images/shelf.jpg");

var card1 = createEquipment("", 10, 7, "images/04_card.jpg", rack);

createLamp(58, 33, "images/lamp_green.png", card1);

createLamp(58, 44, "images/lamp_green.png", card1);

createLabel(58, 63, "QUNEE", card1);

createEquipment("", 354, 13, "images/card1.png", rack);

createEquipment("", 126, 13, "images/card1.png", rack);

createEquipment("", 126, 48, "images/card2.png", rack);

createEquipment("", 126, 82, "images/card2.png", rack);

createEquipment("", 126, 116, "images/card2.png", rack);

createEquipment("", 126, 150, "images/card2.png", rack);

createEquipment("", 126, 184, "images/card2.png", rack);

createEquipment("", 126, 218, "images/card.jpg", rack).size = {width: 441};

var card2 = createEquipment("", 126, 286, "images/card2.png", rack);

createLamp(152, 297, "images/lamp_green.png", card2);

createLamp(165, 297, "images/lamp_green.png", card2);

createLabel(170, 297, "QUNEE", card2, Q.Position.LEFT_MIDDLE);

var port = createEquipment("", 287, 290, "images/port_green.gif", card2);

port.size = {width: 20};

port = createEquipment("", 310, 290, "images/port_green.gif", card2);

port.size = {width: 20};

port = createEquipment("", 333, 290, "images/port_grey.gif", card2);

port.size = {width: 20};

createEquipment("", 126, 321, "images/slot.jpg", rack);

createEquipment("", 274, 320, "images/card3.png", rack);

}

function createEquipment(name, x, y, image, host){

var node = graph.createNode(name, x, y);

node.anchorPosition = Q.Position.LEFT_TOP;

node.image = image;

if(host){

node.host = host;

node.parent = host;

}

return node;

}

function createLamp(x, y, image, host){

var lamp = graph.createNode("", x, y);

lamp.image = image;

if(host){

lamp.host = host;

lamp.parent = host;

}

return lamp;

}

function createLabel(x, y, text, host, position){

var label = graph.createText(text, x, y);

label.setStyle(Q.Styles.LABEL_COLOR, "#FFF");

if(position){

label.anchorPosition = position;

}

if(host){

label.host = host;

label.parent = host;

}

return label;

}
