"Ext.mixin.Observable#addEvents" is deprecated in Extjs 5/6

Question

What can we use instead of addEvents to add an event to the extended class?

this.addEvents({
    "itemclick" : true
});

Answer 1

Since ExtJS 5.0.0 it is no longer required to call addEvents before fireing events. So when you upgrade to ExtJS 5 or newer just delete all calls of addEvents method.
