Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "At the end of the install, you will be prompted to make sure that /usr/local/bin is in your path."

A block of code is set as follows:

Ext.application({
    name: 'Travelly',
    views: [ 'Main' ],
    // ...
    launch: function() {
        Ext.fly('appLoadingIndicator').destroy();
        Ext.Viewport.add(Ext.create('Travelly.view.Main'));
    }
    // ...
});

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

xtype: 'button',
text: 'My button',
id: 'myButton',
handler: function() {
   alert('My button has been clicked!');
}

Any command-line input or output is written as follows:

$ sencha generate model Picture id:int,url:string,title:string,lon:string,lat:string

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Once the installation is complete, you receive a Successful Installation message."

Note
