All examples that I have found so far explain how to render ExtJS (4.2) MVC application within the "viewport", which in other words means full browser screen, and occupying whole HTML BODY.
I would like to render application within the existing HTML page within named DIV, so that I can have HTML design around the application.
<div id="appdiv"><!-- application runs here --></div>
I've seen some sites with ExtJS 4 examples that use trick to render ExtJS app within the page by using IFRAME.
Is it possible to avoid IFRAME? And, if it is, how skeleton of ExtJS 4.2 application shall look like if it will be rendered within a div.
Notes: In ExtJS 3 I have found the solution by creating a panel as main container which renders within named div. However, version 4.2 (and possibly earlier 4.x's) suggests MVC application approach that seem far superior.

I have realised that I have to put starting points for this question.
sencha -sdk /myuserroot/Sencha/Cmd/3.1.1.274 generate app ExtGenApp /mywebroot/htdocs/extja_genapp This generates files and folders and copies all necessary files in the place.index.html (in the root of the generated application)

Ext.application({

views: [
'Main',
'appBoxView'
],
controllers: [
'Main'
],
launch: function() {
new Ext.view.appBoxView({
renderTo: 'appBox'
});; // generates error
}
});
note: originally there is no launch function but there is auto generate viewport (one gets that by default generator)
app/controller/Main.js
Ext.define('ExtGenApp.controller.Main', {
extend: 'Ext.app.Controller'
});
app/view/appBoxView.js
Ext.define('ExtGenApp.view.appBoxView', {
extend: 'Ext.panel.Panel',
requires:[
'Ext.tab.Panel',
'Ext.layout.container.Border'
],
layout: {
type: 'border'
},
items: [{
region: 'west',
xtype: 'panel',
title: 'west',
width: 150
},{
region: 'center',
xtype: 'tabpanel',
items:[{
title: 'Center Tab 1'
}]
}]
});
this shall be initial layout on the screen (AFAIK)
and finally:
app/view/Main.js
Ext.define("ExtGenApp.view.Main", {
extend: 'Ext.Component',
html: 'Hello, World!!'
});
which shall, as I understood, be the "content".
as is, it generates an error of not founding "Ext.view.appBoxView" and how it looks to me, framework do not initialise the application.

Ext JS by Sencha is becoming the ExtJS is a rich, compelling and intuitive open source framework best suited for building single page applications. It offers very rich set of UI components and thus giving a tough competition to other JavaScript frameworks like AngularJS or ReactJS.
Ext JS is a popular JavaScript framework which provides rich UI for building web applications with cross-browser functionality. Ext JS is basically used for creating desktop applications. It supports all the modern browsers such as IE6+, FF, Chrome, Safari 6+, Opera 12+, etc.
You can look at requires as a way to tell ExtJS: "When you construct an object of this class, please make sure to dynamically load the required scripts first".
A viewport is just a specialized Ext.container.Container that auto sizes to the the document body.
As such, you can easily create your own in the launch method:
launch: function(){
new MyContainer({
renderTo: 'myDiv'
});
}
