+ * @GTK_INPUT_PURPOSE_URL: Edited field expects URL
+ * @GTK_INPUT_PURPOSE_EMAIL: Edited field expects email address
+ * @GTK_INPUT_PURPOSE_NAME: Edited field expects the name of a person
+ * @GTK_INPUT_PURPOSE_PASSWORD: Like @GTK_INPUT_PURPOSE_FREE_FORM, but characters are hidden
+ * @GTK_INPUT_PURPOSE_PIN: Like @GTK_INPUT_PURPOSE_DIGITS, but characters are hidden
+ *
+ * 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 @GTK_INPUT_PURPOSE_DIGITS and
+ * @GTK_INPUT_PURPOSE_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'.
+ *
+ * Since: 3.6
