Ext define override

[Fanny144]

When I override a class for example the Spinnerfield I insert this

Ext.define('my.Spinner', {
Ext.define('iBone.field.Spinner', {
    override: 'Ext.field.Spinner',
...
})

and I put the functions that I want override, for example applyValue, but inside this method I put

this.callParent([value])

and it go to the function applyValue of the Ext.field.Spinner and then to the applyValue of the Ext.field.Number, when I want that it go directly to the second option. Because it's supposed I'm overriding this fucntion and the same in the Ext.field.Spinner would cease to exist.

Am I doing something wrong??

Sorry for my English, thanks

You can call the superclass of whatever component via

applyValue : function(newValue, oldValue) {
    return Ext.field.Number.superclass.applyValue.call(this, newValue, oldValue);
}

Thanks for the reply, I'll try it.

But it's supposed that the method callParent() do the proper function when it's called from a overwritten class or it's a bug and it would go to the superclass of the class overwritten and don't to the parent function of the overwritten class??


Thanks again.

You may be needing callOverridden and not callParent, callOverridden !== callParent

[Fanny144]

I tried it with callOverridden and callParent from getValue of a class that overrides Ext.field.Number and two functions go to the same place: getValue function of class Ext.field.Number.


I guess I'll use My.field.Number.superclass.getValue.call(this).


Thanks

how do you know when to use calloverridden, and callparent?
