Removing Arrow From Set Variable in Panel

Share icon

Is there a way to remove the arrows from the setvariable other than create the extreme limits that I did and set the increment to zero?

This is an excerpt of code from the thread here: http://www.igorexchange.com/node/7112

Function OpenCalculatePanel()
    DoWindow/K CalculatePanel
    Newpanel /W=(248,115,730,626)/N=CalculatePanel
    SetVariable sspctrl title="sample start position ",size={400,136},pos={40,400},proc=SetVarProc, value=_num:0, limits={-1000000,100000,0}
        return 0
end
Use the limits keyword.

From Command Help for setVariable


limits={low,high,inc } low and high set the limits of the allowable values for the variable. inc sets the amount by which the variable is incremented if you click the control's up/down arrows. This applies to numeric variables, not to string variables. If inc is zero then the up/down arrows will not be drawn.

It would be nice to not have to clutter the code with these limits at all, but the inf trick makes it less worrisome that I'm gonna error with finite limits. Thanks.

We think the limits are a feature, not a an annoyance. But it's one of those things that reasonable people can disagree on. So in this case, that's Just How It Works.

Which is precisely why we support that usage.

I suppose you're right...I just didn't have a reason to expect to need the arrows, so when I went to eliminate them and saw that I had to impose limits, I had to solve a problem I didn't expect to. +-inf is fine though, it's essentially not having limits at all. Just wasn't aware of the utility of inf :P

Thanks again for your help.
