電信網管系統中,設備狀態信息的實時展現很是重要,一般會掛載一堆圖標來展現狀態或告警信息,圖標的信息量有限,有時須要更詳細的面板,甚至以圖表的形式展示,本文將結合最近客戶提到的需求,使用 Qunee1.6 beta版本,實現拓撲圖中設備信息的實時顯示。html
Qunee 中ui 的定製很是靈活,每一個圖元節點均可以掛載多個 ui 控件,支持9X9=81種相對位置,單節點上能掛載多個 ui 元素,並進行排列和佈局,另外每一個 ui 元素能夠綁定圖元屬性,屬性變化,ui 元素會及時更新界面。 html5
網絡設備拓撲圖,默認設備爲普通節點,雙擊時展開,顯示CPU,內存,流量等信息,使用柱狀圖和不一樣顏色的文字來展現,再雙擊變回普通節點 這裏須要定製節點,普通模式下,節點包含圖標和文字,展開模式下,節點主體變成一個圓角矩陣的面板,上面分佈多個組件:圖標,文字,柱狀圖等,其中柱狀圖能夠參照以前 監控圖例子中的BarUI,其餘都有現成的組件可用,面板使用內置的Shape圖形,圖標依舊使用ImageUI,文字使用 LabelUI,位置分佈則藉助position和 anchorPosition 屬性進行設置node
以 CPU 柱狀圖爲例,左邊是文字,右邊是柱狀圖,文字向右對齊,柱狀圖左對齊 數組
此外,還須要將 CPU 的數值與柱狀圖綁定,這裏用到Q.Element#addUI(ui, bindingProperties)函數,在第二個參數中設定數據綁定,若是有多個屬性須要綁定可使用數組,下面的例子將cpuBar的 data 屬性與 node 的cpu屬性進行了綁定,綁定後就能夠經過node.set("cpu", 0.45)這樣的方式對 ui 進行屬性設置了網絡
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);
實際使用中咱們對函數作了封裝,看起來會不太同樣,下面是節點展開時的 ui 分佈設置,主體爲一個140 X 120的圓角矩形,上面分佈多個文本,圖標和柱狀圖函數
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";
接下來進一步封裝,實現普通模式和展開模式切換,並增長鼠標交互,雙擊進行切換 這裏咱們繼承 Node,定義了一個CustomServerNode類,並增長了showDetail屬性,默認爲 true 表示展開狀態,設置爲 false 時則隱藏全部掛載的 ui,並設置image爲圖片,保留 image 和默認文本標籤佈局
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 ? "雙擊合併" : (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(); if(element){ element.showDetail = !element.showDetail; } }
