[Smtk-developers] Q: Either-or combinations of attribute items

[David Thompson]

> I wonder if we need a find method that is template based - like the addItemDefinition method in Definition.h ?

I would have preferred to do things that way but my shiboken-fu was not up to getting the templated method wrapped (last year). I'm happy to switch the API now.

Yes, but for things like the operators where the attribute items are fixed, I am willing to omit the NULL-pointer checking in favor of legibility.

Also, now that I am exploring conditional children, I see that ValueItem.cxx says:

void ValueItem::updateActiveChildrenItems()
{
  ...
  // Note that for the current implementation only value items with 1
  // required value is support for conditional children.
  // Check to see if the index is valid
  ...
}

and sure enough, when I call setDiscreteIndex() on the "Specification Mode" item, it returns success but then shows 0 active children. Is this expected? I've modified all of the items so they have valid defaults... do they have to be non-default to be considered active?

  Thanks,
