Setting and Accessing Global variables

Question

I need to have a set of Global Variables in a class, and need to access it from other classes. I have the following problems, can someone help me ?

1.) What type of class should i add ? is it a View ? Can someone show an example ? 2.) How can i set values to the variables in this class from my Controller and View classes ? 3.) How can i retrieve the values of these variables from this class (global variable class) ?

note: I know how to add it to the app.js and write/read from other classes. But i want to have a separate class for global variables.

Add them as statics in a new class:

Ext.define('MyApp.util.Utilities', {
    statics: {
        myGlobal: 1
    }
});

At which point you load the class up and from anywhere in the app you can write MyApp.util.Utilities.myGlobal = 5.

This is an extension of my answer here to a similar problem: Where should I define global functions in ExtJS 4 MVC?

Thankyou, so i should Add it in `/MyApp/util/` folder ? If i am using Sencha Architect IDE how am i going to add this file in the said location ? – Sharon Watinsan Jul 23 '12 at 16:41
Yes, but feel free to name it anything you like and put it in the corresponding location. I've never used Architect so I can't help with that, sorry. – David Kanarek Jul 23 '12 at 17:08
How do i `load the class up` ? What do you mean by that ? – Sharon Watinsan Jul 23 '12 at 19:43

Simply require it in any class that uses the globals. See the linked answer above for an example. – David Kanarek Jul 24 '12 at 11:00
