Tk Option Data Types
-
-
- anchor
- Legal values are points of the compass:
"n",
"ne", "e", "se", "s",
"sw", "w", "nw", and also
"center".
- bitmap
- There are eight built-in, named bitmaps:
error,gray25, gray50,
hourglass, info, questhead,
question, warning. To specify an X bitmap
filename, give the full path to the file, preceded with an "@", as in
"@/usr/contrib/bitmap/gumby.bit". See page 164 of Ousterhout's
book for details.
- boolean
- You can pass integers 0 or 1 or the stings
"yes" or
"no"
- callback
- This is any python function that takes no arguments. For example:
def print_it():
print "hi there"
fred["command"] = print_it
- color
- Colors can be given as the names of X colors in the rgb.txt file,
or as strings representing RGB values in 4 bit:
"#RGB", 8
bit: "#RRGGBB", 12 bit" "#RRRGGGBBB", or 16 bit
"#RRRRGGGGBBBB" ranges, where R,G,B here represent any
legal hex digit. See page 160 of Ousterhout's book for details.
- cursor
- The standard X cursor names from cursorfont.h can be used,
without the XC_. For example to get a hand cursor ("XC_hand2"), use
the string
"hand2". You can also specify a bitmap and
mask file of your own. See page 179 of Ousterhout's book.
- distance
- Screen distances can be specified in either pixels or absolute
distances. Pixels are given as numbers and absolute distances as
strings, with the trailing character denoting units:
c
for centimeters, i for inches, m for
millimeters, p for printer's points. Ex: 3.5 inches is
expressed as "3.5i".
- font
- Tk uses the standard X font name format, e.g.
"-*-times-*-r-*-*-*-90-*-*-*-*-*-*". The xfontsel
program for X windows can be handy in browsing and selecting fonts.
See page 162-163 of Ousterhout's book for details.
- geometry
- This is a string of the form "widthxheight", where
width and height are measured in pixels for most widgets (in
characters for widgets displaying text). Example:
fred[
"geometry"] = "200x100".
- justify
- Legal values are the strings:
"left",
"center", "right", and "fill".
- region
- This is a string with four space-delimited elements, each of
which is a legal distance (see above). For example:
"2 3 4
5" and "3i 2i 4.5i 2i" and "3c 2c 4c
10.43c" are all legal regions.
- relief
- Determines what the border style of a widget will be. Legal
values are:
"raised", "sunken",
"flat", "groove", "ridge".
- scrollcommand
- This is almost always the
set() method of some
scrollbar Tkinter widget, but can be any widget method that takes a
single argument. See example files for canvas-with-scrollbars.py for
details.
-
- wrap:
- Must be one of:
"none", "char" or
"word".
