Feed variable value into progress bar?

Share icon

Dear all,

I have an issue with a progress bar I am trying to display in my panel while a loop is running.

The code for my 
ValDisplay
in appearance of a bar is as follows:

ValDisplay valdispProgress,pos={11,448},size={856,12},frame=2,limits={0,100,0}, barmisc={0,0}, value=progress


The problem is, that I get an compile-failure because Igor does not like the 
value=progress
statement.
The variable 
progress
is modified by one of the loops started from the panel and I am not able to hand it's value to the progress bar...

I already tried accessing the Variable 
 progress
by making it a global variable and declaring it directly in the panel:

NVAR progress=root:progress


But this gives me an error - probably because Variables cannot be declared in panels...

How can I acccess my Variable from the panel?

Thanks in advance,

Peter
The answer to your problem depends on how you update your value in your function. Is there any reason why you want to use a variable to hold your update value (e.g., you use it somewhere else, too)? For example, you can just use 
value=_NUM:your_latest_value_here
all the time. Also I am not sure if it is a good idea to use this approach while a loop is running. Can you maybe use a background task to do your task?

So I could access the SetVar from within the loop and set the value this way?

Cool, will try that!

IF you want to use the global variable do this instead

  value=#"root:progress"
