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.
