Mobile text input mystery

[Graham Samuel]

 Reading your response, Mark, I didn't feel so bad, since the LC Dictionary says for example about mobileControlSet

 syntax: mobileControlSet idOrName, PropertyName, value

and later explains

 idOrName  - the id or name of the control

So I therefore saw the two ways of referring to the control as apparently interchangeable.

However, I changed my openCard handler according to your suggestion and nothing at all changed. I think there must be some other factor, but as usual I just can’t see it.

Just to labour the point, here is my actual handler with the original names in place. The answer call works as expected:

on opencard -- we dynamically create a field for the user to key in the radius

global sinputID -- this is all from the LC lesson

   if environment() = "mobile" then

      mobileControlCreate "input", "FRadiusText" -- so the user can type in

      put the result into sinputID

      answer "opening text field for radius input. ID created is:" && sinputID && "Name is:" && "FRadiusText"

     mobileControlSet "FRadiusText", "rect", "114,135,163,158" -- this is where the original rect was

      mobileControlSet "FRadiusText", "visible", "true"

      mobileControlSet "FRadiusText", "opaque", "true"

end if

end opencard


Still puzzled
