'this' is (at any time and any place) a "pointer" to the object whose
code is currently executed. In the above described case it is a
"pointer" to the instance of the class which contains method
resetPositionComboTD(). The code would also work if "this." was
omitted.
'sw' must be a member of the class.
Regards,
Dirk
