How to have a control with a list of boolean checkboxes?

I need to give my users a list of tests to choose from and then do just the tests they selected. Each element in the list would have a string for the test name and a boolean checkbox for the user to select. I'd like to be able to iterate the list of string/boolean.

 

If I create a cluster and make an array out of it I can't seem to either drag the array of cluster into the multilistbox or set the value of MutiColumn ListBox programatically using the following code:

I also managed to make a pretty MultiColumn ListBox but the check mark is just a picture and not a boolean:

How can I create a list of booleans with a ID string that I can iterate to see what is check and what is not?

Why not just an array of clusters? What's the point of the MCLB in this?

I have used listboxes before where clicking (or double-clicking) an entry toggles the check mark symbol to e.g. a blank or an X.

 

(For example, In this application, I populate entries that have already been analyzed with a check mark symbol. In other applications I would toggle double-clicked entries in grey or even strikeout font to exclude them from global analysis (see picture below). There are plenty of possibilities ;))

The "value" of a listbox is an integer that indicates the selected row. (.. or an array of integers if multiple selections are allowed).

 

"Clusters" have nothing to do with any of this.

 

(As you figured out, the item names and symbols need to be set via property nodes.)

Hi flycast,

Generic suggestion:

You can make a distinction between your internal data structures (like an array of clusters) and the data structures needed for "nice" indicators!

 

I really like MCLB controls as you can show a lot of information with lots of formatting options. But most often I create a smal subVI to convert from internal data structure to data needed for MCLB inputs (value vs. other properties)…

Best regards,
