= types: Standard types required by widget options. This  manual  entry describes the the standard types that canbe given as arguments to Inferno Tk widget options.  When  anoption is documented, the type of argument that it accepts iseither documented there, or the name of the  argument  refersto one of the names documented below. anchorPos       One  of the values n, ne, e, se, s, sw, w, nw, or cen‐       ter.  See -anchor in options(9). boolean       A true or false value, one of the  following:  0,  no,       off, false (false), 1, yes, on, true (true). bitmap 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 charac‐       ters  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. color  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 transparent           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 cor‐       responding colour components.  The notation  #rrggbbaa       can  be  used  to describe a colour with alpha (trans‐       parency) component aa;  the  rr,  gg,  and  bb  values       should  be  pre-multiplied  appropriately. This is the       canonical  form  for  colour  values.   Alternatively,       transparency  can be applied to any other colour using       a suffix *alpha where alpha is  either  #aa  (two  hex       digits  representing an alpha value between 0 and 255)       or f (a decimal fixed point number between 0  and  1).       For  example,  red*0.5  gives  half  transparent  red;       #007f007f*#7f gives 0.75  transparent  green  (canoni‐       cally #003f003f). dist   Dist  specifies  a distance on the screen, in the fol‐       lowing 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        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,   /sys/font/pelm/uni‐       code.9.font. frac   A numeric, possibly fractional, value. relief One  of  raised,  sunken,  flat, ridge, or groove.
