toggle boolean buttons

[Jimmy68]

How can I use one button to change the state of another and vice versa.

I have two buttons stop and start.

when I push the start button (condition goes true) I need the Stop button (condition is initially true) to become false.

Thanks in advance

James

Stop is  NOT Start and vice versa.

You can either use locals or property nodes to accomplish this.

James, property nodes are one way to do this. Please see the attached example.

Chris,

I'm using labview 7.1 and can not open the vi

Thanks

James,

Try using an event structure.  Capture the value change event for the buttons and when one goes true, set the other to false via a property node or local variable.

James,

Try this one.

There is no need for any local variables, complicated logic and deeply stacked events.....

All you need is a radiobutton control. 🙂

[altenbach]

An even simpler option would be to use a single boolean that contains a combo picture of the two states.

You only have exactly two states: (1) Start|Stop and (2) Start|Stop, right? So a single boolean can fully describe the overall state!

Here's a quick draft. No code needed at all! 🙂

Altenbach,
How did u make a single boolean object with two button (start/stop) appearance ?
thankyou.

[andre.buurman@carya]

He created a custom control and created and inserted 4 pictures for the different states of the boolean.

Although a very clean solution, the solution with some coding is faster to accomplish and more flexible if requirements change.
