    Default Answered: Inherit from non Component class

    Answered: Inherit from non Component class


    I need to inherit from a non-Component class, in my case from TreeStore.
    I would like to handle events. No initComponent method to override, so that I suppose I need to
    override the constructor to wire up my event handlers.

    Can you give me a short sample? Is there any method I must call?
    Is this the right way?

    Code:
    constructor: function(config) {
      var me = this;
      me.callParent(arguments);
      me.on('move', this.MyMoveHandler);
    }

  2. The overall approach of overriding the constructor is fine. Generally in such circumstances I'd have a read of the superclass's source code to look for a better method to override but from a quick look I don't see a better one for what you're trying to do.
