带有rootVisible = Treepanel = true未显示 [英] Treepanel with rootVisible = true not shown

问题描述

使用 rootVisible：false 时，我的树显示正确。但是将它设置为 true 导致没有树显示，没有错误。

My tree is shown correctly when using rootVisible: false. However setting it to true leads to no tree display and no error.

我的目的是显示根节点我可以定义为 / 或根。如何实现？

My aim is to show a root node that I can define as / or Root. How to achieve this?

我的解决方案：

rootVisible to true 并将其添加到我的树存储区中：

Putting rootVisible to true and adding this to my tree store:

root: {
               id       : '/',
               expanded : false,
               name     : '/',
               type     : 'folder',
               path     : '/',
               root     : true
            }

推荐答案

默认情况下，Rootnode的名称为 Root 。但是您可以指定任何其他名称。

The name for the Rootnode is Root by default. But you can specify any other name.

var store = Ext.create('Ext.data.TreeStore', {
    root: {
        text: "/",
        expanded: true,
        children: [
            { text: "detention", leaf: true },
            { text: "homework", expanded: true, children: [
                { text: "book report", leaf: true },
                { text: "alegrbra", leaf: true}
            ] },
            { text: "buy lottery tickets", leaf: true }
        ]
    }
});

Ext.create('Ext.tree.Panel', {
    title: 'Simple Tree',
    width: 200,
    height: 150,
    store: store,
    rootVisible: true,
    renderTo: Ext.getBody()
});
