Programatically know which index the user has selected of an array of clusters

[lithiumion]

I want to programmatically know which index the user has selected in the panel of an array of clusters.  I didn’t see this option in the property node. Basically, my ultimate goal is to chart the data of the array selected and I need to know how to index that data for the graph.

Hey,

You can use a Event Structure with a MouseDown Event and get the indices via processing them through the coordinates of the MouseDown Event.

Hey

Another option is to display the arrays in a multicolumn listbox and then use an Event structure to find the double clicked row or the invoke node, Get Double Clicked Row.

Maybe you need something more simple...

I think Rkll and me where thinking to far from what you wanted.

For my answer I thought you want to find out which element was selected in a array not via the index display.

Christian,

My apologies because I didn't explain my question well.  Thanks for quick response.

Could someone please save the example as a LV8.1 or earlier vi?  thanks

What is your definition of "selected"? It's not clear enough!

So you have an array of clusters. The index property shows which elements is shown topmost (or leftmost) in the array container, which has nothing to do with any selection, so I am not sure why it got marked it as solution. Is one of the cluster elements a checkbox that indicates "selection" when checked? Do you want to know which element got changed last by the user?

Hello Mike, Here is a screen shot of the code:
