DESCRIPTION

29       This procedure is invoked to add an option to the  database  associated
30       with tkwin's main window.  Name contains the option being specified and
31       consists of names and/or classes separated by asterisks or dots, in the
32       usual X format.  Value contains the text string to associate with name;
33       this value will be returned in calls to Tk_GetOption.  Priority  speci‐
34       fies  the  priority  of  the  value;  when  options  are  queried using
35       Tk_GetOption, the value with the highest priority is returned.   Prior‐
36       ity  must  be  between  0 and TK_MAX_PRIO.  Some common priority values
37       are:

42              files.
43

45              as .Xdefaults, resource databases loaded into the X  server,  or
46              user-specific startup files.
47
48       80     Used  for  options specified interactively after the application
