Hi Kaveh,

The property you're looking for is either
'menuHistory' (this gives you the number of the last
selected line) or 'label' (this gives you the text of
the currently selected line).
As for a message, I'm afraid 'menuPick' is your only
option, and you may want to save the menuHistory on
mouseDown to compare it later in your menuPick
handler.

Hope this helped,

Jan Schenkel.
