Possible to find indices of mouse-over element within 2D boolean array indicator?

[CFER_STS]

I have a high channel count data acquisition system which returns some status indicators, one of which is a boolean indicating whether that particular channel is open-circuit.  I want to be able to display these boolean status indicators in a 2D array of LEDs, such that the operator can see at a glance if any channels are open.  Because the array is large, I want to be able to move the mouse over any LED and have the tip strip indicate the channel number.  How do I access the indices of the moused-over LED in such a manner?

I've never tried exactly what you are doing, but you probably won't be able to get the index directly because it's an array. You should be able to do a mouse over event on the array as a whole and given the size of the booleans calculate what element you are over.

Look at http://forums.ni.com/t5/LabVIEW/Interesting-way-to-detect-array-index-from-mouse-position/m-p/286791...

There are possibly other threads showing similar techniques.

Oooh. I like it. Calculate the indices one time up front and reuse it to determine position...

Here's some very old code of mine that does that.
