extjs 4 门户示例

Question

我想说的是，我很难理解 ExtJS 4 中的门户演示。有人可以为我提供一个容器的通用示例以及如何添加 portlet 项目吗？当我进行搜索时，随下载提供的文档没有“portal”或“portlet”一词。当我查看示例的源代码时，也有类文件和额外的 CSS 文件。需要那些吗？我在网上搜索过，似乎只发现其他人问同样的问题。任何帮助，甚至 extjs 4 演示的链接将不胜感激。也许我的 googlefoo 缺少？

当我使用演示并开始修改边框布局时，我遇到了各种各样的问题。中心区域不能包含选项卡面板，我对东部、西部和北部区域使用手风琴布局。西部地区和手风琴布局似乎存在问题，因为它无法正确显示，即。手风琴就像是半开的，除非您折叠然后重新打开，否则内部的任何图像都不会显示。有人能为我提供一个示例，仅展示如何制作一个基本的门户而不添加任何功能吗？下面是我使用的代码，该代码无法正常工作，但在仅使用视口时显示并工作正常（门户部分除外）。

这是一些示例代码

Ext.define('Ext.app.Portal', {

Answer 1

----------- 仅供阅读此门户布局的任何人使用，它不是官方框架的一部分，而是与库捆绑在一起的第 3 方扩展，这就是它不在文档中的原因。

Answer 2

这是中心区域带有选项卡的门户示例

希望这会对您有所帮助。

Ext.define('Ext.app.Portal', {

    extend: 'Ext.container.Viewport',

                    el = portlet.getEl();

                el.mask('Working...');
                Ext.defer(el.unmask, 2000, el);
