    Answered: Class System: A mixin constructor


    Hello,

    how can I have a mixin constructor to augment the class instance?

    This does not work:
    PHP Code:
    Ext.define('MyApp.mixin.Test', {
        
    extend'Ext.mixin.Mixin',
        
    constructor: function(config) {
            
    console.info('mixin constructor called');
            
    this.initConfig(config);
        }
    });

    Ext.define('MyApp.TestClass', {
        
    mixins: ['MyApp.mixin.Test'],
        
    constructor: function(config) {
            
    console.info('test class constructor called');
            
    this.initConfig(config);
        }
    });

    Ext.create('MyApp.TestClass'); 
    Thanks,
    Roland

  2. You have to call the mixin's constructor manually. It isn't automatic because there's no way for the class system to know when to call it.

    There's an example of this at the top of the docs for Observable:
