From a 2020 discussion…

> State 3 works for me in the C10.12799 IDE Properties by checking “Enabled” in “Value 3rd State” then you must enter a State 3 Value

MUST probably should have emphasized.

Taking it a bit further, I tried setting PROP:State3Value in code. However, this was ONLY applied to the control when STATE3(Value) had been included for the check control on the window. There does not appear to be PROP:State3 itself that presumably might be required prior to using PROP:State3Value.

Am I missing something here or has SV simply not fully implemented the feature?

You can create a state3 check by using CREATE:State3. Then your PROP:State3Value will work as expected.

So a different control than CREATE:Check. Never would have expected that.  
Unfortunately, being able to turn STATE3 on/off based on another control as I had hoped, becomes a bit more problematic.

It is doable, though.

Faking it might be better if one ever needs to revisit the code.

I don’t know, man. Seems pretty simple to write a class that does the thing. In the Init(), pass the original checkFEQ. Create a hidden state3 checkbox. Mimic a few properties. Write a method called setCheckType. Unhide the one you want. Hide the one you don’t.

Agree in principle, especially now that your reply prompted a reminder of the parent parameter in CREATE. However, using hide/unhide on string(s) included on the window MIGHT be made to convey the same information (or actually more) for the users.
