    Hi,

    In my app, i am adding a viewport. On that, i am trying to add the screens and move from one to another. Here is my screens:

    app.js

    Code:
    Ext.Loader.setConfig({    enabled : true
    });
    
    
    Ext.application({
        views : [ 'viewport', 'TitlePanel', 'dashboardpanel'],
        models : [ 'MyModel', 'wishlistmodel' ],
        stores : [ 'name', 'wishlistsummarystore' ],
        name : 'MyApp',
        controllers : [ 'MyController' ],
    
    
        launch : function() {
            console.log('Launchcald');
           Ext.create('MyApp.view.viewport', {
                fullscreen : true
            });
        }
    
    
    
    });


    TitlePanel.js

    Code:
    Ext.define('MyApp.view.TitlePanel', {    extend: 'Ext.Panel',
        xtype: 'loginPage',
        config: {
            ui: 'light',
            items: [
                {
                    xtype: 'panel',
                    id: 'LoginScreen',
                    items: [
                        {
                            xtype: 'image',
                            docked: 'left',
                            height: 130,
                            id: 'Logoimage',
                            ui: '',
                            width: 170,
                            src: 'app/images/logo.png'
                        },

                            height: 100,

    viewport.js

    Code:
    Ext.define('MyApp.view.viewport', {    extend : 'Ext.viewport.Default',
        xtype : 'viewport',
        config : {
            fullscreen : true,
            layout : 'card',
            autoDestroy : false,
            cardSwitchAnimation : 'slide',
            items : [ {
                xtype : 'loginPage'
    
    
            }, {
                xtype : 'dashboardpage'
    
    
            } ]
        }
    
    });



    But unable to see any screens. What i am doing wrong so that my first screen will be TitlePanel.

    Please help.


  2. You shouldn't extend Ext.viewport.Default and you really don't need your own viewport. Ext.Viewport is always going to be instantiated and when you create a component with fullscreen set to true you are actually just adding that component to Ext.Viewport. Ext.Viewport is just a Container using card layout (by default)
