FPM OIF - Event Handling - Howto?

Hi

I'm somewhat new to WDA FPM and need some help on identifying the event as on the apps toolbar and where to handle it?

--> Screen shot of the comp configurator

Each of the view tab are handled as a different view but the apps toolbar is something i need to focus on to read the trigger event and do a set of specific process. I dont know on how to link or find the objects linked to the apps tool bar of the webdynpro comp....appreciate on some pointer/inputs on how to figure it out ........

i'm stil working on how to find the place where the events are handled.
