如何使用ExtJS TreeEditor

Question

我对extjs很新,我想为我的树有一个内联编辑器,我知道在extjs中有一个TreeEditor,我不太清楚如何使用它,有没有人有一个小例子让我开始使用它Ext.tree.TreeEditor？

谢谢

是的,这个确实很糟糕,因为网上没有好的文档.这是一个简短的样本,来自文档和ExtJS in Action:

var tree = new Ext.tree.TreePanel({
    root: this.getChildren(),
    height: 300,
    loader: new Ext.tree.TreeLoader(),
    useArrows: true,
    autoScroll: true,
    listeners: {
        dblclick: onTreeNodeDblClick
    }
});

var treeEditor = new Ext.tree.TreeEditor(tree, {}, {
    cancelOnEsc: true,
    completeOnEnter: true,
    selectOnFocus: true,
    allowBlank: false,
    listeners: {
        complete: onTreeEditComplete
    }
});

onTreeNodeDblClick: function(n) {
    treeEditor.editNode = n;
    treeEditor.startEdit(n.ui.textNode);
}

onTreeEditComplete: function(treeEditor, o, n) {
    //o - oldValue
    //n - newValue
}
