# P

`+PickButton`
  A button labeled "@", used for selecting an object. Like `+ChoButton`, it is a convenience class to provide a style and a tooltip. See also +Tiny, +Tip, +Button, +ChoButton.

`(prev @)`
  Same as 'row' but for the preceding row. The function implementation looks like this:

          (de prev @
             (pass get (: chart 1 data) (row -1)) )

  See row.

`+PwField`
  A standard password field. Does not echo the entered characters back. Example:

          (gui 'pw '(+PwField) 20 "Password")

  This produces a `<passwd>` html tag. See also gui, +TextField and input fields.
