button visible

[marten]

Hello,

How can i make a button visible if a shared variable is true and not visible if that same varable is false...?? is this possible??

Yes, simply create a property node for the button, select property "visible",  change it to write, and wire the boolean value from the shared variable to it.

TRUE: visible, FALSE: invisible. 🙂

hello,

I would like to do the same but the problem is i have to run the vi each time.

My problem is that I would like that to do that in "real time", when I turn off a switch, a button disappears in the display screen.

Can you help me ?

Thanks

Romain

Use an event structure trigger off of the switch value wired into the property node of the control (visible) that you want to appear/dissapear...

To do it in edit mode....

From Diagram: right-click on the terminal and select "hide control or "show control" as desired.

From Front Panel: right-click on the control and select "advanced...hide control or "advanced..show control" as desired.

If you want to switch visibility with a FP control while the VI is in edit mode, you can make an xcontrol consisting of a button and a switch for its visibility. 🙂

Typically, you should design your VI such that it always runs during use. It can be in a wait state when it's not supposed to do anything.
