10. What is Sencha Touch
www.folio3.com@folio_3

11. What is Sencha Touch?
 Sencha Touch, a high-performance HTML5 mobile application
framework, is the cornerstone of the Sencha HTML5 platform.
 Built for enabling world-class user experiences.
 Sencha Touch is the framework that enables developers to build
fast and impressive apps that work on iOS, Android, BlackBerry,
Kindle Fire and more.
 Business Ready Apps for every platform!

12. How It Differs from other HTML5 Mobile App Frameworks
 jQuery Mobile vs Sencha Touch
Sencha Touch jQuery Mobile
Javascript centric Markup centric
UI Widgets, DOM
Manipulation, Server-side
abstraction, MVC
UI-Only Library
Takes time to learn Easier to learn
Supports less browsers Supports more devices then
ST
Imposes a coding structure
and discipline
It does not impose a coding
discipline or structure, which
gives you flexibility
Flexible but at times need to
hack things
Flexible

13. What It Looks Like
www.folio3.com@folio_3

14. Anatomy of an Application
 Models: represent a type of object in your app - for example an e-commerce app might have models for
Users, Products and Orders
 Views: are responsible for displaying data to your users and leverage the built in Components in Sencha
Touch
 Controllers: handle interaction with your application, listening for user taps and swipes and taking action
accordingly
 Stores: are responsible for loading data into your app and power Components like Lists and DataViews
 Profiles: enable you to easily customize your app's UI for tablets and phones while sharing as much code as
possible

15. Getting Started With Sencha Touch
Sencha Touch SDK
http://www.sencha.com/products/touch/download/
&
Sencha Touch SDK-Tools
http://www.sencha.com/products/sdk-tools/download

16. Generate Code – Directory Structure
Inside the app

17. Generated Code – app.js
Ext.application({
name: 'F3AGSession',
views: ['Main'],
launch: function() {
// Initialize the main view
Ext.Viewport.add(Ext.create('F3AGSession.view.Main'));
}
});
Note: Refer files on file system for more details

18. Concepts
 The Class System
 Components
 Containers
 Layouts

19. Sencha Class System
Definition
Ext.define('Animal', {
config: {
name: null
},
constructor: function(config) {
this.initConfig(config);
},
speak: function() {
alert('grunt');
}
});
Instantiate
var bob = Ext.create('Animal', {
name: 'Bob'
});
bob.speak(); // alerts ‘grunt’

20. Sencha Class System – Inheritance
Definition
Ext.define('Human', {
extend: 'Animal',
speak: function() {
alert(this.getName());
}
});
Instantiate
var bob = Ext.create('Human', {
name: 'Bob'
});
bob.speak(); //alerts 'Bob'

21. Sencha Class System – Configuration
 Notice getName, where did that come from ?
 Automatically generates getters & setters
 For example: When name is defined in class config
 setName : Setter
 getName : Getter
 applyName : Setter calls this before actually setting the value.
 updateName : Called when Setter updates the value

22. Sencha Class System – Static Members
Ext.define('Computer', {
statics: {
instanceCount: 0,
factory: function(brand) {
// 'this' in static methods refer to the class itself
return new this({brand: brand});
}
},
config: {
brand: null
},
constructor: function(config) {
this.initConfig(config);
// the 'self' property of an instance refers to its class
this.self.instanceCount ++;
}
});
var dellComputer = Computer.factory('Dell');
var appleComputer = Computer.factory('Mac');
alert(appleComputer.getBrand()); // using the auto-generated getter to get the value of a config property. Alerts "Mac"
alert(Computer.instanceCount); // Alerts "2"

23. Concepts
 The Class System
 Components
 Containers
 Layouts

24. What is a Component?
 Visual Classes
 Every Component in Sencha Touch is a subclass of
Ext.Component

25. What is a Container?
 Sub-class of Component
 Can contain child components
 Can specify Layouts

26. Adding Components to Containers
//this is the Panel we'll be adding below
var aboutPanel = Ext.create('Ext.Panel', {
html: 'About this app'
});
//this is the Panel we'll be adding to
var mainPanel = Ext.create('Ext.Panel', {
fullscreen: true,
layout: 'hbox',
defaults: {
flex: 1
},
items: {
html: 'First Panel',
style: 'background-color: #5E99CC;'
}
});
//now we add the first panel inside the second
mainPanel.add(aboutPanel);

31. Concepts
 The Class System
 Components
 Containers
 Layouts

32. Layouts - HBox
Ext.create('Ext.Container', {
fullscreen: true,
layout: 'hbox',
items: [
{
xtype: 'panel',
html: 'message list',
flex: 1
},
{
xtype: 'panel',
html: 'message preview',
flex: 2
}
]
});

33. Layouts - VBox
Ext.create('Ext.Container', {
fullscreen: true,
layout: 'vbox',
items: [
{
xtype: 'panel',
html: 'message list',
flex: 1
},
{
xtype: 'panel',
html: 'message preview',
flex: 2
}
]
});

34. Layouts – Card Layout
var panel = Ext.create('Ext.Panel', {
layout: 'card',
items: [
{
html: "First Item"
},
{
html: "Second Item"
},
{
html: "Third Item"
},
{
html: "Fourth Item"
}
]
});
panel.setActiveItem(1);

35. Layouts – Fit Layout
var panel = Ext.create('Ext.Panel', {
width: 200,
height: 200,
layout: 'fit',
items: {
xtype: 'panel',
html: 'Also 200px by 200px'
}
});
Ext.Viewport.add(panel);

36. MVC
 Model extends Ext.data.Model
 View extends Ext.Component
 Controller extends Ext.app.Controller

37. MVC - Models
Ext.define('User', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'id', type: 'int' },
{ name: 'name', type: 'string' }
]
}
});

38. MVC - Controller
Ext.define('MyApp.controller.Main', {
extend: 'Ext.app.Controller',
config: {
control: {
loginButton: {
tap: 'doLogin'
},
'button[action=logout]': {
tap: 'doLogout'
}
},
refs: {
loginButton: 'button[action=login]'
}
},
doLogin: function() {
// called whenever the Login button is tapped
},
doLogout: function() {
// called whenever any Button with action=logout is tapped
}
});
