Hi Alex,
I did not followed exactly this thread but just some thoughts:
In my plugins I use often popup menus I treat as they were "normal"
menus called by clicking on a "normal" button.
In the "normal" button script:
on mouseDown
if the platform = "MacOs" then ShowPullDownMenu
end mouseDown
----------------------------------------------
on mouseUp
if the platform <> "MacOS" then ShowPullDownMenu
end mouseUp
----------------------------------------------
on ShowPullDownMenu
<statements> -- building the menu in a variable named tMenu
put the bottomLeft of me into tLoc
if the platform = "MacOS" then add 2 to item 2 of tLoc
else subtract 2 from item 2 of tLoc
put tMenu into btn <popup button name> -- the items I want
popUp btn <popup button name> at tLoc
end ShowPullDownMenu
Note that the behaviour can't be the same for Mac and Win32.
You could adapt the ShowPullDownMenu handler in order to act
accordingly to your context: ie display a menu or do another action.
Hope but don't know if this helps :-)

This cannot be as hard as I'm making it ..... so I'll follow the
excellent advice from the list of not struggling over a simple
issue for more than an hour and ask for help. Though I am about
4 hours late .... :-(
Easy bit:
I want to have a button, that acts like a pop-up button - i.e. when
I click on it, up pops a list of choices and I can select one - or
I can click outside the list of options and get a "cancel"
indication back. When a choice is made, I do the appropriate action.
This is what I get with a "pop-up menu" selected from the IDE's
tool palette.
Hard part:
Sometimes, there is only one valid choice; in that case, I'd like
to go ahead with the appropriate action immediately - don't present
a menu, just do the action.
I can put in a handler for the mouseDown to the pop-up button - but
can't find a way to avoid it popping up.
I tried putting in another button, and having its mouseDown take
the action - either just doing it, or sending mouseDown to the pop-
up button - but apparently; sending a mouseDown isn't enough to
trigger the pop-up.
(I tried a large number of other things, but I'm not going to
embarrass myself by listing them all ....)
