每当我尝试设置布局类型覆盖并且我不确定是什么导致它时,我都会遇到布局运行失败。

我有一个父视图,它有一个标签面板作为子项:

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视图:

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,这将有效:

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

如果省略,则视图加载没有问题,但是当我包含 hbox 类型时,我会运行失败。

我尝试查看调用堆栈,但老实说,我仍然对 sencha 保持绿色以查看导致错误的原因:

在尝试使用除默认设置以外的任何布局类型时,我如何设置视图会导致失败?

当容器的布局设置为hbox时,该容器的子级应具有flexwidth。如果您指定flexwidthgrid那么您将不会面临布局运行失败。
