Gui status - In alv OO

Hi experts,

I created a button in the gui status.

i defined lcl_handle_event and did implementation.

the method i use: on user command.

My problem is:

When i click the button in the gui status after i ran the alv report i expect that it will do what i wrote in the implementation - and its not even get there.

what should i do to make him do as i wrote in the implementation of the class?

Thank,

Michal.
