20.1.6.6 Tk Option Data Types
- Legal values are points of the compass:
"n","ne","e","se","s","sw","w","nw", and also"center". - 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". - You can pass integers 0 or 1 or the strings
"yes"or"no". - This is any Python function that takes no arguments. For example:
def print_it(): print "hi there" fred["command"] = print_it - 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. - The standard X cursor names from cursorfont.h can be used,
without the
XC_prefix. 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. - 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:
cfor centimetres,ifor inches,mfor millimetres,pfor printer's points. For example, 3.5 inches is expressed as"3.5i". - Tk uses a list font name format, such as
{courier 10 bold}. Font sizes with positive numbers are measured in points; sizes with negative numbers are measured in pixels. - 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). For example:
fred["geometry"] = "200x100". - Legal values are the strings:
"left","center","right", and"fill". - 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. - Determines what the border style of a widget will be. Legal
values are:
"raised","sunken","flat","groove", and"ridge". - This is almost always the set() method of some scrollbar
widget, but can be any widget method that takes a single argument.
Refer to the file Demo/tkinter/matt/canvas-with-scrollbars.py
in the Python source distribution for an example.
- Must be one of:
"none","char", or"word".
