Expand description
Describes primary purpose of the input widget. This information is useful for on-screen keyboards and similar input methods to decide which keys should be presented to the user.
Note that the purpose is not meant to impose a totally strict rule about allowed characters, and does not replace input validation. It is fine for an on-screen keyboard to let the user override the character set restriction that is expressed by the purpose. The application is expected to validate the entry contents, even if it specified a purpose.
The difference between Digits
and
Number
is that the former accepts only digits
while the latter also some punctuation (like commas or points, plus,
minus) and “e” or “E” as in 3.14E+000.
This enumeration may be extended in the future; input methods should interpret unknown values as “free form”.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive

Name
Edited field expects the name of a person
Password
Like FreeForm
, but characters are hidden
