Sequence of Method call

I am lost in understanding the following piece of code:

Let me explain the way I understand this:
1. btnOpen object is instantiated of datatype Button.
2. setOnClickListener method on the object btnOpen is invoked. To this method we need to pass an object (I guess no variable is mentioned, but lets assume 'x' is passed).
a. As this object does not exist yet, a constructor for the object is invoked:

Here, I guess the author has actually coded the constructor.
b. Within the constructor, a method is invoked (on which object???).

Can someone explain me the method call sequence?

Thanks and Regards,

AWT and Swing event listeners are triggered by user interaction - a mouse click, key press, etc.
