Legal values are points of the compass: "n", "ne", "e", "se", "s", "sw", "w", "nw", and also "center".
位图
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".
boolean
You can pass integers 0 or 1 or the strings "yes" or "no".
callback — 回调
This is any Python function that takes no arguments. For example:
def printit():
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 `XCprefix. 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.<br />distance<br />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”.<br />font<br />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.<br />geometry<br />This is a string of the formwidthxheight, where width and height are measured in pixels for most widgets (in characters for widgets displaying text). For example:fred[“geometry”] = “200x100”.<br />justify<br />Legal values are the strings:“left”,“center”,“right”, and“fill”.<br />region<br />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.<br />relief<br />Determines what the border style of a widget will be. Legal values are:“raised”,“sunken”,“flat”,“groove”, and“ridge”.<br />scrollcommand<br />This is almost always theset()method of some scrollbar widget, but can be any widget method that takes a single argument.<br />wrap<br />Must be one of:“none”,“char”, or“word”`.
