LabVIEW

Is it possible to create a set of mutually exclusive dialog radio buttons in such a way that only one radio button per set can be selected at a time? Can LabVIEW detect which buttons are pressed to ensure only one is set to true before the program runs?

I would create a couple events/or case, in which if one radio button is pressed, the rest are disabled (or even disabled and grayed). This way you will be able to ensure that only one button is pressed at the time!

The proper way of doing this is, believe it or not, with a customized slide control. It looks like radio buttons and outputs the number of the option selected.

Attached is a VI showing two I put together. To use them use the text control at the bottom of the control to set the name of the buttons, or add new ones by adding items to the list.

Once you have the items configured, right click on one of the buttons and select Visible>>Text Display to hide the text display and you're read ro rock and roll.

This is very good.

Only wish I could take credit for it, but it came about at least two or three major revs ago...

Thanks Mike for the great way of doing things!
I wonder how did you customize the slide control to make it look that the VI that you've attached with your answer?

Yeah. I've always wondered why this radio button technique hasn't made its way to the standard control palette yet. IIRC the codeless radio button was first published by Stepan Riha in LTR long ago.

Basically, when you go into edit mode you can copy and paste graphics to be used for different display components. I made the marker indexes look like unselected booleans, and the slider look like a selected boolean.
