javascript - ExtJS Ext.panel.Panel 工具命令

Question

我有这个面板。它按以下顺序显示工具图标:齿轮、关闭、折叠。我想得到的图标是这样的顺序:齿轮、折叠、关闭。我想不通。当我把 collapseFirst: true 放在第一位时，collapse 就在第一个位置。

Ext.application({

    launch : function() {
        Ext.create('Ext.panel.Panel', {

Answer 1

编辑:发现覆盖 initTools 方法是更好的解决方案

编辑 2:同时支持 ExtJS 4.2 和 ExtJS 5.x

Ext.create('Ext.panel.Panel', {
        width : 500,
        height: 500,
        title : 'Panel',

        closable : true,
        collapsible : true,
        collapseFirst : false,

            type : 'gear'
        }],
