how to get index of cluster and make popup vi for every event

[kalu]

Hi

I have problem. the problem is i have to find out the index of cluster.

I have an event "mouse down" from this cluster  and index should be the value where i put my mouse.

2nd thing is curently i am just abel to display only 1 popup. but i need each pop up for every every element where i move my mouse

thanks in advance.

1. Your event is not Mouse Down, but Mouse Move

2. Clusters don't have in index, only arrays. Therefore you can't return an index.

3. You can attempt to use the mouse coordinates to work out which element of the cluster has been selected, and work out the equivalent of an index.

4. What's wrong with just using the array control instead of a cluster? Then you have an index that you can properly determine.

Hi

Use a "value change" event on the array and do a "not equal" on the old a new value. Only the changed value will result in a  true. Use search array to find the TRUE in the "not equal" array and the resulting index points to the changed element. You can do basically the same with clusters, by using "cluster to array" at the right time.

(If you insist on using mouse down events, you can gt the coordinates from the event terminals and thus calculate where it went down.)

It is possible because there is a cluster toolkit in VIPM that has an Index Cluster function.

Here's what I had in mind (LabVIEW 8.2)
