[Smtk-developers] [Cmb-users] Dealing with passwords in attributes

[David Thompson]

Hi John (and Yumin),

I think the boolean is too restrictive; we will almost certainly come up with other roles that require special processing. (I am thinking of roles related to how input is accepted but that are not UI-specific. For example, indicating that a DoubleItem should be a point on a surface instead of in the interior; that informs the UI that a point selector will work but does not specify UI elements to achieve it.)

So in that sense, I agree with Yumin that a single boolean is too narrow. However, I do not think there needs to be a separate class just for passwords (or any other role).

To me, the closest analog is the html <input> element, which has a "type" attribute that can be set to many different values -- e.g., button, checkbox, color, date, file, hidden, radio, url -- as well as"password" and the default "text". As for the many other "type" choices, the ones relevant to simulation preprocessing are already handled differently in SMTK; so I would go for the boolean flag.
