Multiple text ring sharing same items

[jbphili]

I'd like to have multiple text rings, all having the same list of item/value pairs. How do I do that? While I can copy the same text rings it'd very bothersome if I want to update the list. I have not been successful in Googling for this.

Thank you very much.

Ideas:

• Use an Enum instead?
• Wire a constant array of strings to the Strings[] property node for all the rings.

I'd go with an enum.

But if the list has to be dynamic, create an array references of the rings and use a FOR loop to update the items.

I thought enum is the same as text ring except it doesn't allow customized Values (always sequential from 0)

And even when I tried that I still don't see a way to share the list.

I think what I want is closer to Type Def. But when I tried that I noticed even when I update my .ctl, the control that uses is is not update accordingly.

If you make a type def enum, then every control that is linked to that type def will have the exact same list.  If you make a type def ring, they will not.  If you make a Strict Type Def ring, then they will have to look exactly the same, but they will have the same list.

What exactly are your requirements?  What are you trying to do with these controls?  Is the list dynamic (can change at runtime)?

I'll try the strict type def ring.

I want non-sequential values to control scaling of waveform chart. I have multiple waveform charts so I need multiple of those ring sharing the same list of scaling factors. No run time changes needed.

Thanks.
