  27  * @short_description: A dialog used to set, change or remove a password.
  28  * @see_also: #HildonGetPasswordDialog
  29  *
  30  * HildonSetPasswordDialog allows setting and changing a password.
  31  *
  32  * In Change mode: Dialog is used to change or remove an existing
  33  * password. Unselecting the check box dims the password fields below
  34  * it. If the dialog is accepted with 'OK' while the check box is
  35  * unselected, a Confirmation Note is shown.  If the Confirmation Note
  36  * Dialog is accepted with 'Remove', the password protection is removed.
  37  *
  38  * In Set mode: Set Password Dialog is used to define a password, or
  39  * change a password that cannot be removed.
