Well, that works fine.  I get a checkbox that switches between unchecked, checked and the square one (don't know the name of it ).

The problem is...  PlusWnd.Button_IsChecked("ChkTest") returns true for both checked and the 3rd.  Is there a way to check which one it is?  And also, can it be set to the 3rd with PlusWnd.Button_SetCheckState("ChkTest", ThirdState)?

The "square" one is usually used for sub-groups of options isn't it?

You know that if it's checked, the user has selected at least one sub-item... If not, you can pretty much ignore them (assume they are false)

Well, I'm actually going to use them as part of Interface Writer, for editing multiple items (with the square selection for not changing a particular item).
