Tk_AddOption is invoked to add an option to the database
associated with tkwin's main window. Name contains
the option being specified and consists of names and/or classes
separated by asterisks or dots, in the usual X format. Value
contains the text string to associate with name; this value
will be returned in calls to Tk_GetOption. Priority
specifies the priority of the value; when options are queried using
Tk_GetOption, the
value with the highest priority is returned. Priority must
be between 0 and TK_MAX_PRIO (100). Some common priority
values are:
- TK_WIDGET_DEFAULT_PRIO
(20)
- Used for default values hard-coded into widgets.
- TK_STARTUP_FILE_PRIO (40)
- Used for options specified in application-specific startup
files.
- TK_USER_DEFAULT_PRIO (60)
- Used for options specified in user-specific defaults files,
such as .Xdefaults, resource databases loaded into the X
server, or user-specific startup files.
- TK_INTERACTIVE_PRIO (80)
- Used for options specified interactively after the application
starts running.
Tk_GetSystemDefault returns a Tcl_Obj* with the string
identifying a configuration option matching the given dbname
and className. Returns NULL if there are no system defaults
that match this pair.
