正如标题所暗示的那样,我有一个面板,它将执行一个命令onRender来添加项目,如下面的代码,一个treepanel。我在一个布局中包装了treepanel - border,然后在一个vbox面板上将它放在了west的区域。不幸的是整个树面板都没有渲染。我检查了HTML,并且元素在那里,但它们有点被禁用,因为元素在firebug中有那么模糊的字体。它为什么这样做?请帮忙。
Ext.define('anr.panels.report', {
extend : 'Ext.panel.Panel',
pageLimit : 15,
title : 'Report Generator',
layout : 'border',
border : false,
frame : true,
initComponent: function() {
this.callParent(arguments);
},
onRender:function() {
var me = this;
var store = Ext.create('Ext.data.TreeStore', {
root: {
expanded: true,
children: [
{ text: "detention", leaf: true },
{ text: "homework", expanded: true, children: [
{ text: "book report", leaf: true },
{ text: "algebra", leaf: true}
] },
{ text: "buy lottery tickets", leaf: true }
]
}
});
var reportItem = {
xtype: 'panel',
layout: 'vbox',
id:'westpanel',
region:'west',
width: 350,
height: 300,
minSize: 350,
maxSize: 350,
border: false,
split: true,
margin: '1 0 5 1',
items: [
{
border: false,
layout: 'border',
items:[
{
xtype: 'treepanel',
height: 250,
width: 200,
store: store,
id: 'menu-panel',
frame: false,
rootVisible: false
}
]
}
]
};
this.add(reportItem);
this.callParent(arguments);
}
});

我不确定你为什么使用onRender方法而不是将面板放在项目中,但无论如何都有太多的错误。
每个边框面板都需要高度,宽度或弯曲度,并且需要一个面板具有中心区域。
如果您将代码更改为此代码,它会起作用,但要小心所有这些嵌套面板,您似乎迷路了。
