javascript - 布局运行失败

Question

每当我尝试设置布局类型覆盖时，我都会遇到布局运行失败，但我不确定是什么原因导致的。

我有一个父 View ，它有一个选项卡面板作为子项:

Ext.define('InventoryDemo.view.main.Main', {
    extend: 'Ext.panel.Panel',
    xtype: 'app-main',

    requires: [
        'Ext.plugin.Viewport',
        'InventoryDemo.view.brand.Brand'
    ],

    title: '<h1>Inventory Demo</h1>',
    layout: 'border',

    items:[
        {
            ...
        },
        // This is the tab panel that I'm trying to add the container class to
        {
            xtype: 'tabpanel',
            title: 'Inventories',
            header: false,
            region: 'center',
            reference: 'inventoryTabSet'
        }
    ]
});

这是我试图作为选项卡添加到选项卡面板的 View :

Ext.define("InventoryDemo.view.inventory.list.Inventory",{
    extend: "Ext.container.Container",
    xtype: 'inventory',

    ...

    closable: true,
    layout:{
        type: 'hbox',
        align: 'stretch'
    },
    items:[
        {
            xtype: 'grid',
            bind:{
                store: '{inventory}'
            },

            listeners:{
                itemclick: 'showDetails'
            },

            columns:[
                { text: 'Name', dataIndex: 'name', flex: 1 },
                { text: 'Price', dataIndex: 'price' },
                { text: 'Active', dataIndex: 'active' },
            ]
        }
    ]
});

如果我不包含布局配置，这会起作用:

    layout:{
        type: 'hbox',
        align: 'stretch'
    },

如果遗漏了， View 加载没有问题，但是当我包含 hbox 类型时，我运行失败。

我试着查看调用堆栈，但老实说，我仍然需要 sencha 来查看导致错误的原因:

在尝试使用除默认布局类型以外的任何布局类型时，我如何设置 View 会导致失败？

Answer 1

当容器的布局设置为 hbox 时，该容器的子容器应具有 flex 或 width。如果您为grid指定flex或width，那么您将不会面临布局运行失败。
