Hi Dibya, changing texts of boolean buttons is possible with property nodes. You can change captions, tip strips, and text on button (property strings[4])... What is an Enginner? A combination of engineer and beginner? edited: WTH is happening here? In the preview I have linefeeds, in the post I get block text???

Also take a look here http://decibel.ni.com/content/docs/DOC-4819

You may even use animated gifs. Se example. But I do not know how it impact performance if you have many such controls with animated gifs.

Hi Dibya,

LabVIEW provides a way to change the image of the control according to the state.

1) In the advanced menu of the Push Button there is an option called customize.

2) Clicking on this will convert the Push Button into a custom control and opens the editor.

3) Before proceeding further copy the image which you want to apply to the clipboard.

4) In the control editor, pop up on the control and you will find an option called "Import Picture from Clipboard".

5) Using this option you can set the copied image for True or/and False state.

Try this out and let me know if this works out well... 🙂

You can use a Picture control and monitor mouse down in a fashion similar to a boolean. You can put anything you want (and are capable and willing to code) in a picture control (been there, done that). See here for a collection of links to threads with example using the picture control.

If those link inspire you to do something novel and interesting, pleas feel free to post back with your implementation and we can add your example to the collection.

Have fun,

Ben

Here's a quick and easy hack:

Drop a button that looks nice.  I used Silver/Boolean/Blank.

Place a picture ring on top of it

Drop a transparent button on top of that, and expand it to match.  I used Classic/Boolean/Square, then set FG/BG to transparent.

To make it a little nicer, I turned the bottom button into an indicator and connected it to the transparent button.  The operator would never know the difference, and the icon can change however often you like.

You can't change the image dynamically, but you can change the string.  Here is an example.  I have a raised box decoration, with a transparent picture, and a transparent button on top.

1.) Run the VI

2.) Select the image path for the ON/OFF states.

3.) Enter the message for the ON/OFF states.

4.) Press the button to see how it behaves.

You can change this on the without stopping the VI.
