Dependend Buttons

[mariuszl2]

Hi, I have a small problem.

I have three buttons in front panel and only one of them should be ON at the same time.

Example: Button 1 is pressed when VI starts. When I press Button 2, Button 1 should switch OFF and so on.

I`m using Event structure and references to do this,

but when I make it into a subvi it has inputs for the references. Is there any other way to do it?

I attached my Vi below. Hopefully it will give You understanding of what I`m trying to do.

Have you considered using Radio Buttons?

You could use OpenG's "Get Current VIs Parents Reference" to get a reference to the main VI and then use an invoke node to get/set the control's values using their label.

The other option at the top of by head is to make an array of the references to pass into the subVI and the index of which control changed. Then use a for loop to set the others.

You could store the buttons in one cluster or array, and if a value change event is triggered you could XOR the old and the new values, that should only keep the changed button 'TRUE'.

Further question is it possible to turn all buttons of?

If so, the XOR trick won't work.

No. one button is always on. I think I`m gonna do it by inserting normal buttons inside Radio buttons. I didn`t know I can do that

Thank you, you lovely lovely person

Two days ago I was writing something and I was thinking to myself, I am sure I have seen a VI somewhere that returned a parent's refernece, but could I find it.

So of to rewrite my little VI, thanks again,
