old code for ToggleShow [nim], taken from testdraw2_cannib.py
# types
##ImageWidget = Widget # not sure if we want this to be a definite subtype
# could it be renamed to Image? possible name conflict (probably ok): import Image # from the PIL library
# I'll rename it.
# == ToggleAction
from __Symbols__ import stateref
ToggleAction = NamedLambda( ###e need to initialize the state if not there? NO, that's the job of the stateref (formula) itself!
'ToggleAction',
((stateref, StateRef),),
Set(stateref, not stateref) ### will 'not' be capturable by a formula?
## [update 061204: lhs and rhs are both wrong now, see Set.py -- lhs must be lval, rhs must be not stateref.value or so [nim]]
)

Overlay(Hidden(false_icon),Centered(true_icon)), # get the size of false_icon but the look of true_icon

#e Overlay might work better outside, if otherwise something thinks the layout depends on the stateref state
false_icon
),
# highlighted image - ###e make this a lighter version of the plain image
#e or a blue rect outlining the plain image -- I forget if Button assumes/implems the plain image always drawn under it...

# actions -- for now, just do it immediately when pressed
