Defines a user function to be called when a system button is clicked.
GUISetOnEvent ( specialID, "function" [, winhandle] )

You can not call a function using parameters.
If Opt ("GUIEventOptions", 1) the minimize, restore and maximize button will not do any action on the window just a simple notification.
If the function is an empty string "" the previous user-defined is disabled.
