Question

I have got the tabpanel – it’s the main form (view).
In this tabpanel I define the different tabs – xtype:'panel'.

So, I have one main(controller) , main view and some tabs views.
The tab’s views are referenced in main view.

I want to define listener of activate event of some child’s panel in main controller.

How can I do that?

the main controller :

Ext.define('KP.controller.account.apartment.Main', {
    extend: 'Ext.app.Controller',

    views: ['account.apartment.Main',
        'account.apartment.Requisites'
    ],

    models: ['account.apartment.Requisites'
    ],
    stores: ['account.apartment.Requisites'
    ],


    init: function () {

    }
});

The main view:

Ext.define('KP.view.account.apartment.Main', {
    extend: 'Ext.window.Window',
    alias: 'widget.ApartmentData',

    height: 566,
    width: 950,
    activeItem: 0,
    layout: {
        type: 'fit'
    },
    autoShow: false,

    initComponent: function() {
        var me = this;

        Ext.applyIf(me, {            
            items: [
                {
                    xtype: 'tabpanel',
                    activeTab: 0,
                    deferredRender: true, 

                    items: [                        

                        {
                            xtype: 'RequisitesApartment'
                        }
                    ]
                }
            ]
        });

        me.callParent(arguments);
    }

});

The child panel RequisitesApartment (view):

Ext.define('KP.view.account.apartment.Requisites', {
    extend: 'Ext.panel.Panel',
    alias: 'widget.RequisitesApartment',


    id: 'panel_accountrequisites',
    height: 350,
    width: 1124,
    autoScroll: true,
    layout: {
        type: 'fit'
    },


    listeners: {
        activate: function () {           
               ....load data....
               ...this listeners I want to push in 'main' controller...            
        }
    },

    initComponent: function () {
        var me = this;

        var grid_store = Ext.create('KP.store.account.apartment.Requisites');

        Ext.applyIf(me, {
            dockedItems: [
                {
                    xtype: 'gridpanel',
                    height: 260,
                    autoScroll: true,
                    dock: 'bottom',
                    store: grid_store,
                    id: 'r_gridFlatParams',
                    forceFit: true,


                    columns: [
                        ...some columns....
                    ],
                    viewConfig: {
                }
            }
            ]
        });

        me.callParent(arguments);
    }
});

Register it directly as control within the responsible controller

Here is a example with a working query. For sure you just will need the query, but I think it’s a good example. The custom cfg property ident make it easy find each tab. As in the example below you will have specify a tabConfig within each panel and define the ident there.

Ext.create('Ext.tab.Panel', {
    width: 400,
    height: 400,
    renderTo: document.body,
    items: [{
        title: 'Foo',
        tabConfig: {
            ident: 'foo'
        },
    }, {
        title: 'Bar',
        tabConfig: {
            ident: 'bar',
            title: 'Custom Title',
            tooltip: 'A button tooltip'
        }
    }]
});

console.log(Ext.ComponentQuery.query('tabpanel tabbar tab[ident=foo]')[0]);
console.log(Ext.ComponentQuery.query('tabpanel tabbar tab[ident=bar]')[0]);

Another way is to use css id’s which can be queried like '#my-name' but I recommend to use a custom one as in the example above
