You'll begin with basic design principles for building great mobile applications, and then explore the features of Sencha Touch that bring those ideas to life. You'll learn how and why objects operate in the framework as you work through several real-world examples. This book also promotes the emerging best practices for mobile web development, from widget implementation to developing an application with the Sencha Touch MVC framework.

What makes Form panels so special anyway? An overview of the different Form widgets. Maps and media 9. Maps in your application. Layouts However, a basic question remains: How does the parent component know how to embed the children component, particularly regarding its location on the screen? Layouts will be described in great detail in Chapter 3. It is very simple to attach functions as event handlers: The only thing that is required is to specify a listeners configuration element to your user interface object.

This event triggers the execution of the corresponding function, which takes a certain number of parameters; the Sencha Touch documentation, described in the next section, provides the exact definition of the parameters required in every one of the events exposed by the framework.

Events will be described in more detail in Chapter 3. This approach will be explained in Chapter 6. This way, you will always find your way and, should you inadvertently close the browser window, the same pages will be opened for you the next time you access the documentation, as shown in Figure Sencha documentation tabs Another handy feature of the built-in documentation system is integrated, full-text client-side search; type any text on the search field on the top right of the documentation browser, and you will be able to find your way.

You can type any kind of API, function, even xtypes; all of them are just a keystroke away. Figure shows how this brilliant search system works. Sencha Touch Documentation System 21 www. Even better, as we will learn in Chapter 8, you can generate the same kind of documentation for your own projects!

Conclusion This chapter has shown you how to download the Sencha Touch distribution, and how to write and understand the basic principles of every application created with the framework. The next chapters will explore in depth different aspects of Sencha Touch, used to create very complex applications. This framework provides a higher-level object-oriented abstraction on top of JavaScript, allowing developers to define classes and to create instances using a syntax similar to that of other programming languages.

This chapter ends with a discussion of the various extensions provided by Sencha Touch around the JavaScript core language and APIs, making developers write better cross- browser compatible code.

These variations show the infinite flexibility of software, and the adaptability of design patterns to different situations and environments.

Sencha Touch is no different, as it provides yet another form of MVC, this time adapted to applications running on mobile web browsers. Figure shows the typical structure of Sencha Touch MVC applications, which includes several new structural components: Data-bound views are tied to stores in such 23 www. Both stores and proxies are explained in detail in Chapter 4. Sencha Touch 2 application architecture 24 Chapter 2: The Class System www.

As you saw in Chapter 1, the code of your applications is contained within the app folder, located next to the index. If for some reason you need to override this default location, the app. Inside the app folder, the application code is structured as follows: The reality sinks in quite fast, though; JavaScript does not have classes, at least not in the traditional sense of the word, but simply function templates that create in-memory Understanding the Class System 25 www.

JavaScript has only literal objects and functions; and with those two building blocks, you will create all of your web applications. Sencha Touch tries to simplify and hide the quirkiest parts of JavaScript by providing its own class system; this makes it possible for developers to think about JavaScript in more traditional ways, defining classes and creating new instances from those.

As such, the Sencha Touch class system is based upon two main functions: Both Ext.

ClassManag er. However, the latter methods are considered private, and you should always use the shorthand functions instead. List', xtype: CustomList; this class extends the Ext. Classes defined using Ext. Base, as do all the classes in the Ext namespace. Base is not the same as Ext. Class, which is a class factory used internally by Ext.

CustomList class, which is exactly what we wanted to do here. If you need to provide some extra configuration, just add a second parameter to the call to Ext. This property has a special meaning to Sencha Touch, and it represents a mapping between a class name and a shorter name, easier to type and remember.

In short, you can think of the xtype as an alias to the real name of a class in the Sencha Touch class system. Thanks to the xtype property, Sencha Touch objects can be instantiated both with the Ext. When reading this parameter, Sencha Touch will automatically create the object of the corresponding class. Alternatively, the Ext. The following table shows the xtype values of different classes available in Sencha Touch.

XmlStore To use the xtype syntax, just create a standard JavaScript dictionary and use it in the items property of your panel, just as you would use any other instance. These components are also described in detail in Chapter 4. The following chapters will deal with every one of these families in detail; we are going to start our exploration with the foundation utilities family, which is used throughout the framework.

Understanding the Class System 29 www. This section contains a summary of the most important functions available in Sencha Touch; for a complete description of each API, please refer to the documentation. Ext The Ext root object also used as root namespace by Sencha Touch contains a large number of useful functions and properties.

This function is required to solve some quirks inherent to JavaScript. Similarly, Ext. Finally, Ext. The function also takes as parameters the context of execution, some optional arguments, and of course the number of milliseconds before executing the function.

For more control over delayed execution, check the Ext. DelayedTask class, which provides tighter control and more options. Please refer to the section about Ext. The objects passed as parameters of this function will be removed from the DOM, and their event listeners will be removed as well. The callback function can be return false at any time to stop the iteration process. Foundation Utilities 31 www. Array[2] addConfig: Button" extend: Object superclass: Object triggerExtended: On the other hand, getStore is a shortcut to Ext.

Sencha components are explained in detail in Chapter 3, while stores are described in Chapter 4. Array or Ext. Object, as required. This is the output of the preceding code: This is done immediately and synchronously, which means that the JavaScript code can reference those objects right after the namespace function call. Done' ; console. I know it will help you learn quickly and painlessly. It was really helpful and well explained.

A very nice start for the Sencha Touch technology. Are you wondering how to learn Sencha Touch quickly? The building blocks of a Sencha Touch application. How to create an application with multiple views, and how to implement intuitive navigation patterns. How to create list-based and master-detail user interfaces in a Sencha Touch application. These are some of the reasons why you will love this eBook: You do not need to have prior knowledge of Sencha Touch.

You will find all you need to know to go from zero to a working app in the book. You will not get bored reading tons of framework references because the book is not a rehash of the Sencha Touch documentation. You will not find yourself wondering how something in the book works. The book is written in a style that you can understand, with clear explanations and examples.
