我扩展了一个组件，我无法将其渲染到面板。似乎我错过了一些非常基本的东西，因为Chrome中的调试器实际上显示该面板有数据，它只是没有出现。
以下是fiddle，以下是代码的一部分：
自定义组件：
Ext.define('StoplightControl', {
extend: 'Ext.draw.Component',
alias: 'widget.Stoplight',
constructor: function (config) {
this.initConfig(config);
this.callParent(arguments);
},
initComponent: function () {
var kpiData; // = Ext.data.StoreManager.get('KPIStore').getById(this.model.get('KPI_ID'));
if (typeof (kpiData) === 'undefined' || kpiData == null) {
kpiData = Ext.create('KPIModel', {
ControlBackground: '#000000',
Caution_label: 'On',
Good_label: 'Ahead',
Poor_label: 'Behind',
Good_color: '#00FF00',
Poor_color: '#ff0000',
Caution_color: '#550000',
Header: 'Test'
});
}
this.setGradients(kpiData.get('ControlBackground'));
this.drawItems(this.model, kpiData);
},
setGradients: function (controlColor) {
this.gradients = [{
id: 'middleGradient',
angle: 180,
stops: {
0: {
color: controlColor,
opacity: 1
},
50: {
color: controlColor,
opacity: .6
},
100: {
color: controlColor,
opacity: 1
}
}
}, {
id: 'lightGradient1',
angle: -90,
stops: {
0: {
color: '#ffffff',
opacity: 0.01
},
100: {
color: '#ffffff',
opacity: .8
}
}
}]
},
drawItems: function (model, kpiData) {
var cautionValueX = -22.5 * (model.get('cautionValue').toString().length) + 227.5,
goodValueX = -22.5 * (model.get('goodValue').toString().length) + 227.5,
poorValueX = -22.5 * (model.get('poorValue').toString().length) + 227.5,
maxLineLength = 15,
changeOfY = -50,
cautionLabel = linebreaks(kpiData.get('Caution_label'), maxLineLength),
goodLabel = linebreaks(kpiData.get('Good_label'), maxLineLength),
poorLabel = linebreaks(kpiData.get('Poor_label'), maxLineLength),
cautionChangeY = (cautionLabel.split("\n").length - 1) * changeOfY,
goodChangeY = (goodLabel.split("\n").length - 1) * changeOfY,
poorChangeY = (poorLabel.split("\n").length - 1) * changeOfY,
headerFontSize = '100px arial,sans-serif',
textFontSize = '80px arial,sans-serif';
var drawItems = [{

//don't add gradients if IE is > 10 or documentMode is less than 9
if (!(ie > 10 || document.documentMode < 9)) {
drawItems.push({
type: "ellipse",
id: 'test1',
radiusX: 112,
radiusY: 80,
x: 224,
y: 156,
fill: 'url(#lightGradient1)'
}, {
type: "ellipse",
radiusX: 112,
radiusY: 80,
x: 224,
y: 498,
fill: 'url(#lightGradient1)'
}, {
type: "ellipse",
radiusX: 112,
radiusY: 80,
x: 224,
y: 838,
fill: 'url(#lightGradient1)'
});
}
},
width: 210,
height: 250
});
创建Panel并添加组件：
var displayPanel = Ext.create('widget.panel', {
width: 600,
height: 800,
title: 'Cost & Schedule Variance',
renderTo: 'WorkstreamStoplights',
pack: 'center',
shrinkWrap: 3,
layout: {
type: 'table',
column: 2
},
});
stoplightStore.each(function (model, idx) {
var stoplight = Ext.create('StoplightControl', {
model: model
});
displayPanel.add(stoplight);
});
displayPanel.doLayout();
正如您可以从小提琴中看到的那样，标题显示正确，我甚至在创建displayPanel时添加了一个项目，但执行.add()似乎没有即使使用.doLayout()
