Events on elements of cluster

[TommyBoy]

Hi,

I have a cluster with 500 boolean controls (week-calender).

I want to detect some events on these boolean controls :

- mouse enter

- mouse leave

I could create an 'enter'-event case and a 'leave'-event case,

and then assign the enter- or leave- events of the 500 controls

to these 2 cases.

But that would take hours because I have to assign each event to this

case individually for every control.

Is there a way to do this faster :

Can I assign all 'mouse enter' events on the 500 controls to 1 event case

where the case tells you on which control the mouse has entered using a ref?

Hi

Could you maybe give information, what you want to do? Maybe there is a good solution.

By the way - I don't know a way that could solve what you describe.

You can compare the New value with the Old value with a "Not equal" comparison, convert the resuting booleanc luster to an array and then search for TRUE.  This will give you the index of the cluster elements which has changed.

Now you can use the Controls[] property of the cluster reference with this index value to get a reference to the actual boolean which has changed.

Example included (LV 6.1).

Hope this helps

Shane.

Edit: In hy hectic, I failed to notice you actually want Mouse enter and Mouse leave events.

This is much harder.  I advise solving the problem in another way.  LV 6.1 doesn't actually have Mouseover events......

Shane:

A little bit easier than compare on "not equal" is to just XOr the old and the new value.

Hello Tomy,

does it have to be a cluster? Can't you use an array of booleans instead? This way it's much easier to maintain...

[shoneill]

Becktho,

Er, yup, that's right.

However, I still find "Not equal" easier on the eyes.  I've no hardware background and I always have to do some mental acrobatics when trying to work out what those boolean operators do with non-boolean data.......

Don't mind Shane

I just picked it up somewhere in the forum, as I wanted to code radio-buttons to work properly.

Hi,

a little more information on the setup :

It's a calendar, where each boolean control represents an hour.

I want to change the front an backcolour when hoovering over the actual control.

Doesn't have to be in a cluster, just easier to code (500 terminals!)

I have not found a way to create one event case state, that gives you feedback

over which control that you hoovered.

Please advise!

Tommy.

Instead of 500 booleans for each hour, wouldn't it be easier to use a numeric control for the hour?  Put limits in the control to define min and max values.  If you put focus on the control, the user just has to type in a number and press Enter.

You can use dynamic events to register all your booleans at once. See Pict.
