Field Incr/Decr Button Widget

Just a thought, haven't looked myself. Is there a min/max function such that you could do something like set(min(limit, new value)) and similar for decreases? I know the syntax is whack, but the concept is there.

[Dean Roddey]

There isn't anything like that currently, but it's fairly simple to do. Just something like:

Code:

If (System::LessThan(%(LVar:NewValue), minval))
    LocalVars::SetValue(LVar:NewValue, minval);
EndIf;

That will just clip it to the lowest value. And similarly the other way for clipping to the max.

There is a IsInNumericRange, which will check if a value is within a given range, but that's not exactly what you need.

I guess the innumericrange could be used as a single test for both up and down.

Earlier today I discovered LinkToField, and it is going to save me a LOT of time creating a thermostat popup (and many other location-aware things). The only issue is that with the loss of inc/dec functionality, I have to use a Command Button widget to change temperatures, and that widget (understandably) doesn't support LinkToField.

Does anyone know of a way to implement inc/dec and LinkToField at the same time?

[Dean Roddey]

Just save the moniker of the current thermo in a global variable. The actions can reference that moniker to create the target fields names, so something like:

Devices::WriteField(%(GVar:CurThermo).Mode, xxxx, True);

That sort of thing.

Oh wow - that's great! I already have the value in a GVar - that's how I'm passing context for the LinkToField settings.

The more I use actions, the more I appreciate what a nice job you did on dynamically building values. :-) At first I thought it was odd that you were saving actual text values for field and variable references, rather than some kind of internal ID. But now I understand. ;-)
