The meaning of Ring Control

Hi All,

 

I have been using LabVIEW for a year now.

 

I just have a simple question about "Ring Control"

I know how it works but i just don't know why it is called the "Ring" control.

 

I noticed that the continuous clicking of the increase button will go through the list like a "ring"

But enums do the same as well.

 

Is it just me that is curious about this?

 

Regards,

Jeff

Hi Jeff

 

As I understand it the main difference is that you can define both the string and numeric values of items in a ring control, whereas you can define only the string values of items in an enum. Another difference is that the string values of items in an enum cannot be changed at run-time.

 

There's a KB addressing this distinction here.

 

Kind Regards

Umm, maybe i missed a point.

So why is it called the "ring" control again?

As shown above letters and numbers are arranged in a ring about a circle. There is a one to one relationship between the letters and the numbers. Given a letter you can find a number of vise versa. While the Secret Decoder Ring shown above was intended to encode/decode secret messages, a letter at a time the same idea can be extended to make a connection between a uniques set of words or phrases and numbers.

 

The ring control is simply a virtual Little Orphan Annie Decoder Ring where you can define translations.

I was wondering what you were trying to say with the picture.
