Class Object Constant border black

[ASTDan]

Hello,

I was wondering why the constant or control of a class object is sometimes black.  What does this mean?

Thanks

Control vs constant?

They are both constants.  

Thanks

No, I think they're both constants. At least in LV 2016 the control is flat, not 3D looking. I think the standard white border indicates that the constant has default values for all data, and the black border indicates non-default value(s).

The black border signifies that data has been saved in the constant (as opposed to just the normal default values for the constant). This occurs when you create a constant from a Control that contained data from a previous execution of a SubVI, for example.  So it means be aware you are not starting from scratch! (this may of course be the desired situation).
