anchorPos One of the values \f5n, \f5ne, \f5e, \f5se, \f5s, \f5sw, \f5w, \f5nw, or \f5center. See -anchor in options (9).
boolean A true or false value, one of the following: \f50, \f5no, \f5off, \f5false (false), \f51, \f5yes, \f5on, \f5true (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 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 .
color A color parameter can be a colour name or an RGB (red, green and blue luminance) value. The colour names recognized are: .EX 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 corresponding colour components. The notation #rrggbbaa can be used to describe a colour with alpha (transparency) 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 (canonically #003f003f).
dist Dist specifies a distance on the screen, in the following 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, /fonts/pelm/unicode.9.font .
frac A numeric, possibly fractional, value.
relief One of \f5raised, \f5sunken, \f5flat, \f5ridge, or \f5groove. See -relief in options (9).
