TYPES(9)TYPES(9)NAMEtypes - Standard types required by widget options.
DESCRIPTION
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.
anchorPos
One of the values n, ne, e, se, s, sw, w, nw, or center. 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 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:
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 compo‐
nents. The notation #rrggbbaa can be used to describe a colour
with alpha (transparency) component aa; the rr, gg, and bb val‐
ues should be pre-multiplied appropriately. This is the canoni‐
cal 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 raised, sunken, flat, ridge, or groove. See -relief in
options(9).
