     TYPES(9)                                                 TYPES(9)

          types - Standard types required by widget options.

          This manual entry describes the the standard types that can
          be given as arguments to Inferno Tk widget options. When an
          option is documented, the type of argument that it accepts
          is either documented there, or the name of the argument
          refers to one of the names documented below.

               One of the values n, ne, e, se, s, sw, w, nw, or cen-
               ter.  See -anchor in options(9).

               A true or false value, one of the following: 0, no,
               off, false (false), 1, yes, on, true (true).

               Identifies an image which can be drawn, or used as a
               mask through which something else is drawn. If bitmap
               begins with a `@', the remaining characters must be the
               path name of an Inferno image file. If bitmap begins
               with the character `<', the remaining characters must
               be a decimal integer giving the file descriptor number
               of an open file (see sys-open(2)) from which the bitmap
               can be loaded. Otherwise, bitmap should be the name of
               a bitmap file in the directory /icons/tk.

               A color parameter can be a colour name or an RGB (red,
               green and blue luminance) value. The colour names rec-
               ognized are:
                   aqua     yellow   red      teal     white
                   fuchsia  black    blue     darkblue
                   maroon   gray     green    lime
                   purple   navy     olive    orange
               For RGB values, either #rgb or #rrggbb can be used,
               where r, rr, etc. are hexadecimal values for the corre-
               sponding colour components.

          dist Dist specifies a distance on the screen, in the follow-
               ing form: an optional minus sign (-), then one or more
               decimal digits (with possible embedded decimal point),
               then an optional units specifier. The unit specifiers
               are the following:

               c    centimetres

               m    millimetres

     TYPES(9)                                                 TYPES(9)

               i    inches

               p    points (1/72th inch)

               h    height of widget's font (only applicable if the
                    widget has an associated font, and if the font has
                    previously been set).

               w    width of the zero (0) character in widget's font.
                    (see above).

               Measurements are converted into pixels assuming 100 dots
                    per inch on an average CRT display.

          font A font parameter gives the full path name of an Inferno
               font file; for example, /fonts/pelm/unicode.9.font.

          frac A numeric, possibly fractional, value.

               One of raised, sunken, flat, ridge, or groove. See
