Why are there four different images for a boolean ind or control and how can I utilize them?

well, there are 4 states:

- switched off

- switched on

- switching to off

- switching to on

 

Using system controls you get two more states:

- mouse over switched off

- mouse over switched on

Hi Gearimiester,

 

My name is Jonathan and I work within the Applications Enginering department at NI in the UK, 

 

These images look to be images saved to the clipboard in the customisation of the control/indicator so rather than using a lit up LED you could have a specific image representing the state, Are you wanting to utilise all 4 of the images? Obviously boolean is 1 of 2 states.... True or False so really only 2 states can be used and therefore only 2 representing images.

 

You could edit 4 boolean indicators to be transparent wehn they are false and use the images to be the true value rather than a colour and then overlay each one on top of the other. 

 

If you let me know what it is you are specifically looking to achieve I would be happy to help.

 

Cheers

OK - Is there any way to access the other states with a blink property node so as to change the image from on to say switching to off? I was trying to impliment a different png image for the blinking property.

 

Thanks for the reply!

Jonathan~

 

Yes they are my custom png files and see reply above for application.

 

Your solution is workable and I have done it with some other button - indicator applications but I have found that if I do this while the indicators are inside a cluster it really draws on the cpu while idle and slows down the application when running. So I was trying to avoid having to do that if possible.

Hi,

 

no, using the Blink property just changes some colors…

 

When you want free control of the shown image you could use a PictRing instead…

HI,

 

I guess you could use property nodes to edit the blinking of the LED. I personally edited the Indicator and replaced the standard green block with an image from file.

 

Ive attached some steps below:

Thanks for the input guys.

 

I think I will check out the ring control option and use it as the indicator. now I just need to work out how to control it programmatically.
