Tab / Vbox布局

我有一个使用Tab布局的应用程序,其中每个表单面板之间的xtype小部件共享相同的网格面板。

我的主要标签布局如下:

Ext.define('cardioCatalogQT.view.main.Main', {
    extend: 'Ext.tab.Panel',
    xtype: 'main-view',
    controller: 'main-view',
    requires: [
        'cardioCatalogQT.view.main.MainController',
        'cardioCatalogQT.view.main.MainModel',
        'Ext.ux.form.ItemSelector',
        'Ext.tip.QuickTipManager',
        'Ext.layout.container.Card'
    ],

    style: 'background-color:#dfe8f5;',
    width: '100%',
    height: 400,

    layout: 'vbox',
    defaults: {
        bodyPadding: 5
    },
    items: [{
            title:'Main',
            region: 'south',
            xtype: 'form',
            itemId: 'Ajax',
            flex: 1,
            styleHtmlContent: true,
            items:[{
                xtype: 'image',
                src: 'resources/images/R3D3.png',
                height: 50,
                width: 280
            },{
                title: 'Ad Hoc Sandbox for Cohort Discovery'
            }] ,
            lbar:[{
                text: 'Initiate advanced request',
                xtype: 'button',

                handler: function(button){
                    var url = 'https://url_here';
                    //cardioCatalogQT.service.UtilityService.http_auth(button);
                    window.open(url);
                }
            }]
        },
        /*{
            xtype: 'resultsGrid'
            //disabled: true
        },*/
        /*{
            xtype: 'searchGrid'
            //disabled: true
        },*/
        {
            xtype: 'demographicGrid'
            //disabled: true
        },
        {
            xtype: 'vitalGrid'
            //disabled: true
        },
        {
            xtype: 'labGrid'
            //disabled: true
        },
        {
            xtype: 'diagnosisGrid'
            //disabled: true

        },
        {
            xtype: 'medicationGrid'
            //disabled: true
        },
        {
            xtype: 'procedureGrid'
            //disabled: true
        },
        {
            xtype: 'queryGrid'
            //disabled: true
        }
    ]
}); 

共享相同网格窗口小部件的各个选项卡(特别是demographicGrid,vitalGrid,labGrid,diagnosticGrid,procedureGrid和medicationGrid,每个在主视图中由xtype引用)看起来像:

/**
 * Widget with template to render to Main view
 */

Ext.define('cardioCatalogQT.view.grid.DemographicGrid', {
    extend: 'Ext.form.Panel',
    alias: 'widget.demographicGrid',

    requires: [
        'cardioCatalogQT.view.main.MainController'
    ],


    config: {
        variableHeights: false,
        title: 'Demographics',
        xtype: 'form',
        width: 200,
        bodyPadding: 10,
        defaults: {
            anchor: '100%',
            labelWidth: 100
        },


        // inline buttons

                        button.up('grid').down('#showSex').hide();
                    }
                }
            }, {

                        {name: 'male', value: 'm'}
                    ]
                }
            },{
                //minWidth: 80,
                text: 'Add to search',
                xtype: 'button',
                itemId: 'searchClick',
                handler: 'onSubmitDemographics'
            }]
        },
            {
                xtype:'searchGrid'
            }
        ]

    }


});

选项卡中每个表单面板之间的唯一区别是项目组件。这些表单面板中的每一个都引用了一个xtype的'searchGrid',并在附加的图像中呈现它:Tab rendered with searchGrid

问题是我有这个相同网格的6个实例。这在很大程度上起作用,但是它导致了一些与控制网格中的复选框相关的问题以及一些奇怪的网格存储加载行为,老实说,使用这种反模式跟踪组件是PITA。

我想在一个较低的垂直面板中以某种方式在我的searchGrid中有一个实例,而一个上面的垂直面板包含我需要根据每个选项卡的要求更改的项目组件。项目控件如何变化的示例是Different panel with different item components

我希望的行为是,当我点击一个标签时,上面的项目组件会将我带到另一个表单面板,而下面板保持固定在搜索网格上。

但是,我目前将searchGrid绑定到每个选项卡的表单面板,因为这是我可以使用它的唯一方法。

searchGrid网格面板如下所示:

Ext.define('cardioCatalogQT.view.grid.Search', {
    extend: 'Ext.grid.Panel',

    xtype: 'framing-buttons',
    store: 'Payload',
    itemId: 'searchGrid',

    requires: [
        'cardioCatalogQT.view.main.MainController'
    ],

    columns: [
        {text: "ID", width: 50, sortable: true, dataIndex: 'id'},
        {text: "Type", width: 120, sortable: true, dataIndex: 'type'},
        {text: "Key", flex: 1, sortable: true, dataIndex: 'key'},
        {text: "Criteria", flex: 1, sortable: true, dataIndex: 'criteria'},
        {text: "DateOperator", flex: 1, sortable: true, dataIndex: 'dateComparatorSymbol'},
        {text: "When", flex: 1, sortable: true, dataIndex: 'dateValue'},
        {text: "Count", flex: 1, sortable: true, dataIndex: 'n'}
    ],
    columnLines: true,
    selModel: {
        type: 'checkboxmodel',
        listeners: {
            selectionchange: 'onSelectionChange'
        }
    },

    // When true, this view acts as the default listener scope for listeners declared within it.
    // For example the selectionModel's selectionchange listener resolves to this.
    defaultListenerScope: false,

    // This view acts as a reference holder for all components below it which have a reference config
    // For example the onSelectionChange listener accesses a button using its reference
    //referenceHolder: true,

    // inline buttons
    dockedItems: [{
        xtype: 'toolbar',
        dock: 'bottom',
        ui: 'footer',
        layout: {
            pack: 'center'
        }
    }, {
        xtype: 'toolbar',
        items: [{
            //reference: 'andButton',
            text: 'AND',
            itemId: 'andButton',
            tooltip: 'Add the selected criteria as AND',
            iconCls: 'and',
            disabled: true,
            handler: 'onCriterionAnd'
        },'-',{
            //reference: 'orButton',
            text: 'OR',
            itemId: 'orButton',
            tooltip: 'Add the selected criteria as OR',
            iconCls: 'or',
            disabled: true,
            handler: 'onCriterionOr'
        },'-',{
            //reference: 'notButton',
            text: 'NOT',
            itemId: 'notButton',
            tooltip: 'Add the selected criteria as NOT',
            iconCls: 'not',
            disabled: true,
            handler: 'onCriterionNot'
        },'-',{
            //reference: 'removeButton',  // The referenceHolder can access this button by this name
            text: 'Remove',
            itemId: 'removeButton',
            tooltip: 'Remove the selected item',
            iconCls: 'remove',
            disabled: true,
            handler: 'onCriterionRemove'
        },'-', { // SaveQuery
            //reference: 'SaveQuery',
            text: 'Save',
            itemId: 'saveQuery',
            tooltip: 'save the current filter',
            iconCls: 'save',
            disabled: true,
            handler: 'onFilterSave'
        }]
    }],

    height: 1000,
    frame: true,
    iconCls: 'icon-grid',
    alias: 'widget.searchGrid',
    title: 'Search',

    initComponent: function() {
        this.width = 750;
        this.callParent();
    }
});

我使用Vbox布局搞砸了我想要的行为,但是相当不成功。这看起来并不常见,例如,根据Tab单击,上部Vbox面板更改为不同的表单面板,而下部Vbox面板保持固定状态。任何见解都会受到欢迎。

如果我理解正确,我的这个小测试应该完全符合您的要求,使用区域northcenter的边框布局。
