Ext.Application Question

[stefan.vissia]

Hi all,

I'm looking into EXT 4 and came by the Ext.Application class, in the source code i find some instructions how to use it:

new Ext.Application({
    name: 'MyApp',

    launch: function() {
        this.viewport = new Ext.panel.Panel({
            fullscreen: true,

            id    : 'mainPanel',
            layout: 'card',
            items : [
                {
                    html: 'Welcome to My App!'
                }
            ]
        });
    }
});

This code is not running because of a call within Ext.Application to Ext.Viewport.init, this does not exists because the in EXT4 the correct init call would be Ext.container.Viewport, correct?

Is the Ext.Application ready to use, or will this feature be released in a futere release?

Thanks,

I had the same issue, it seems there is a bug in Ext.Application. I am assuming the viewport will automatically be created in a future release as the documentation states; however the following changes in your code worked for me:

new Ext.Application({
    name: 'MyApp',
    autoInitViewport: false,
    launch: function() {
        this.viewport = new Ext.container.Viewport({
            fullscreen: true,

            id    : 'mainPanel',
            layout: 'card',
            items : [
                {
                    html: 'Welcome to My App!'
                }
            ]
        });
    }
});
