The above works, but is it just me who finds the use of 'data instead
of 'state odd for a check box? The default values are none for 'data
yet false for 'state, which suggests it's meant to be 'state but
View's altering 'data instead. This show's what I mean...
view layout [
text "Click on the check box and watch the output."
x: check [print reform ["x/data:" x/data "x/state:" x/state]]
do [print reform [
"Default Values: x/data:" x/data "x/state:" x/state
]]
]
Which gives me this output...
Default Values: x/data: none x/state: false
x/data: true x/state: false
x/data: false x/state: false
x/data: true x/state: false
x/data: false x/state: false
etc...
So, is it a bug, or am I missing something and a check box with a none
as its default makes sense?
