What is this data type?

I've inherited some code and there's an odd control on the front panel. It's an array on the front panel but seemingly an integer on the block diagram.

It's a Multicolumn Listbox.

If you right-click the control on the front panel and go to properties, that dialog will have the control type in the title bar. Alternatively, right-click the control on the block diagram, select Create, then Reference and the reference you drop will also have the name of the control type visible.

The integer value you can read/write is the 0-based index of the row which is selected.

Awesome thanks for the info. All these years and I've never seen one of those things.

Why would you use this over an array of integers?

It doesn't just support integers, each cell is actually a string. You use property nodes to get/set these values. It's a very powerful control if used properly, go to Help > Find Examples... and search for listboxes. Check out the Properties Tutorial example.

Very powerful also = very finicky and frustrating when not used properly.
