How to restrict file type using xtype filefield(extjs 4.1.0)?

Question

I am trying to implement file upload feature using extjs 4.1.0. Whereas I want to restrict users to select only image files(jpg,png,gif). Is there any filter which can be applied so that users will only be able to see and then select the types of the files mentioned above?

You could stuff like this as well :

    {
        xtype: 'filefield',
        buttonText: '....',
        listeners:{
            afterrender:function(cmp){
              cmp.fileInputEl.set({
                accept:'image/*' // or w/e type
              });
            }
        }
    }
