Enumerated Control Items

[pacific]

I have an enum control with three items (example:- x = 0, z = 1, c =2). On the front panel, when I use the increment/decrement buttons, these three items are displayed in alphabetical order (c,x,z). Is it possible to display the items in the order of their numeric values (x,z,c)? I cannot change their numeric values as I am using them to update a control property node. Hence that option is ruled out.

Thanks

I'm not sure I see what you mean.

The letters just cycle through as I click the increment/decrement buttons. If I click inside the control, I get a list of items to choose.

I'm using LabVIEW8.

I am sorry, the example I gave was wrong...suppose x=0, c=1, z=2. In this case when you use the increment/decrement buttons it cycles through as x - z - c. Is it possible to have the enum cycle as x - c - z?

If you start at "x" the order will be x-c-z when you use the down increment and x-z-c when you use the up increment. This is by design.

Thanks for the replies. My understanding of the problem was wrong. (The increment/decrement directions got me confused) The enum dose display the items in the order of their numeric value.

Thanks once again.

Why is it designed like this?

I must admit that I hadn't paid any attention to the order that the labels are displayed when using the increment/decrement arrows.

Enumerated types are used to limit variables values to specific ones.

As those you specify will be the only ones, assigning values is not necesary, but they are added to help management.

One way to assign values is to give the first one value 0, and add one to every value as they enter into the group. That's an enumerated value.

So, if they are values that increment by one, using arrows to increment by one makes sense. When you reach the last one, as the only values are the ones in the list, it's normal to go to the first one

If you'd prefer to assign specific values to specific names (other than sequential starting by 0) and reorder names unacordingly to their values, you can use a Ring control

Hope it helps,

Because it "wraps around". If you look at the choices vertically:
    x
    c
    z
then if you start at x and go up, it wraps around to the bottom, giving x-z-c. I recall there being a debate a long time ago about whether or not it should stop at the top/bottom. You can see for yourself what the outcome was.

If it is a show-stopper, you can always eidt the images on the up/down bottons (in the control editor) and swap their positions.

Great tip Ben.
