Tri-state checkboxes

[Dave]

Hi,

Just create a small image and set the contents depending on the state  
which you keep in a Custom Property.

Something like this would do it:

on mouseUp
local myCurrentState


put the cpCurrentState of me into myCurrentState
if myCurrentState = empty then
put 0 into myCurrentState
end if

add 1 to myCurrentState
if myState > 3 then
put 1 into myState
end if


switch myCurrentState

case 1
set the fileName of me to "File1"
break

case 2
set the fileName of me to "File2"
break

case 3
set the fileName of me to "File3"
break

end switch

set cpCurrentState of me to myCurrentState
end mouseUp

Of course you don't need to use an image file you could just use an  
Icon, but this should serve as a basis.

Hope this Helps
All the Best
Dave
