Here's a recipe (from the Cookbook) to do this (this example changes the
text color, but you can do whatever you want instead):


local didPopUpMenu -- keeps track of whether the menu was popped up

on mouseDown
  put false into didPopUpMenu -- start out by assuming no menu
  send "popGoesTheMenu" to me in 2 seconds
end mouseDown

on popGoesTheMenu theLocation
  -- The menu will pop up only if the user is still pressing
  -- the mouse over the button after 2 seconds:
  if the mouse is up \
     or the mouseLoc is not within the rect of me \
     then exit popGoesTheMenu
  put true into didPopUpMenu -- skip the mouseUp actions
  popup button "Colors" -- the hidden popup menu
end popGoesTheMenu

on mouseUp
  -- if the user popped up the menu, don't do the click action
  if didPopUpMenu then pass mouseUp
  -- if there is a text selection, set its color:
  if the short name of the selectedField is "Example Text" then
    set the textColor of the selectedChunk \
       to (last word of the label of me)
  end if
end mouseUp
