    Default adding items

    adding items


    Hi,

    I have simple code written in ext js 3.4

    Code:
    Ext.onReady(function()
            {
        var myForm = Ext.extend(Ext.FormPanel,{
                width : 100,
                height : 200,
                items : [ 
                         {
                                fieldLabel : 'First Name',
                                xtype : 'textfield',
                                name : 'FName',
                                allowBlank : false
                            }
    
    
                        ], 
                 initComponent: function(){
                    this.title = 'Login Form';
                   /*this.items : [                      {
                                fieldLabel : 'First Name',
                                xtype : 'textfield',
                                name : 'FName',
                                allowBlank : false
                            }
    
    
                        ];*/
                    myForm.superclass.initComponent.call(this);
                }
    
                    
                });
                
                
                
                var f = new myForm();
                f.render(document.body);
            });
    In this code 'items' property is added outside of initComponent function. If I add same property within initComponent and uncomment the code then component is get rendered. I really not able to understand what is happening here..

    We do not support putting complex objects in the prototype of an extended class. When you do this, the objects will be shared across instances of classes and in essence become static.

    Prior to calling the parent class's initComponent method you can view what is in this. items.

    After invoking the parent class's initComponent method you can view what is in this.items

    You would never be able to set the "Property" items directly.
    You can invoke the "Method" add after the component is setup.
