.SH NAME
option \- Add/retrieve window options to/from the option database
.SH SYNOPSIS
.nf
\fBoption add \fIpattern value \fR?\fIpriority\fR?
\fBoption clear\fR
\fBoption get \fIwindow name class\fR
\fBoption readfile \fIfileName \fR?\fIpriority\fR?

.SH DESCRIPTION
.PP
The \fBoption\fR command allows you to add entries to the Tk option
database or to retrieve options from the database.  The \fBadd\fR
form of the command adds a new option to the database.
\fIPattern\fR contains
the option being specified, and consists of names and/or classes
separated by asterisks or dots, in the usual X format.  \fIValue\fR
contains a text string to associate with \fIpattern\fR;  this is the
value that will be returned in calls to \fBTk_GetOption\fR or by
invocations of the \fBoption get\fR command.  If \fIpriority\fR
is specified, it indicates the priority level for this option (see
below for legal values);  it defaults to \fBinteractive\fR.
This command always returns an empty string.
.PP
The \fBoption clear\fR command clears the option database.  Default
options (from the
\fBRESOURCE_MANAGER\fR property or the \fB.Xdefaults\fR
file) will be reloaded automatically the next time an
option is added to the database or removed from it.  This command
always returns an empty string.
.PP
The \fBoption get\fR command returns the value of the option
specified for \fIwindow\fR
under \fIname\fR and \fIclass\fR.  If several entries in the option
database match \fIwindow\fR, \fIname\fR, and \fIclass\fR, then
the command returns whichever was created with highest
\fIpriority\fR level.  If there are several matching
entries at the same priority level, then it returns whichever entry
was most recently entered into the option database.  If there are
no matching entries, then the empty string is returned.
.PP
The \fBreadfile\fR form of the command reads \fIfileName\fR,
which should have the standard format for an
X resource database such as \fB.Xdefaults\fR, and adds all the
options specified in that file to the option database.  If \fIpriority\fR
is specified, it indicates the priority level at which to enter the
options;  \fIpriority\fR defaults to \fBinteractive\fR.
.PP
The \fIpriority\fR arguments to the \fBoption\fR command are
normally specified symbolically using one of the following values:
.TP
\fBwidgetDefault\fR
Level 20.  Used for default values hard-coded into widgets.
.TP
\fBstartupFile\fR
Level 40.  Used for options specified in application-specific
startup files.
.TP
\fBuserDefault\fR
Level 60.  Used for options specified in user-specific defaults
files, such as \fB.Xdefaults\fR, resource databases loaded into
the X server, or user-specific startup files.
.TP
\fBinteractive\fR
Level 80.  Used for options specified interactively after the application
starts running.  If \fIpriority\fR isn't specified, it defaults to
this level.
.LP
Any of the above keywords may be abbreviated.  In addition, priorities
may be specified numerically using integers between 0 and 100,
inclusive.  The numeric form is probably a bad idea except for new priority
levels other than the ones given above.
.SH EXAMPLES
Instruct every button in the application to have red text on it unless
explicitly overridden:
.CS
\fBoption add\fR *button.foreground red startupFile
.CE
.PP
Allow users to control what happens in an entry widget when the Return
key is pressed by specifying a script in the option database and add a
default option for that which rings the bell:
.CS
entry .e
bind .e <Return> [\fBoption get\fR .e returnCommand Command]
\fBoption add\fR *.e.returnCommand bell widgetDefault
.CE

260	.SH DESCRIPTION
261	.PP
262	The \fBoption\fR command allows you to add entries to the Tk option
263	database or to retrieve options from the database. The \fBadd\fR
264	form of the command adds a new option to the database.
265	\fIPattern\fR contains
266	the option being specified, and consists of names and/or classes
267	separated by asterisks or dots, in the usual X format. \fIValue\fR
268	contains a text string to associate with \fIpattern\fR; this is the
269	value that will be returned in calls to \fBTk_GetOption\fR or by
270	invocations of the \fBoption get\fR command. If \fIpriority\fR
271	is specified, it indicates the priority level for this option (see
272	below for legal values); it defaults to \fBinteractive\fR.
273	This command always returns an empty string.
274	.PP
275	The \fBoption clear\fR command clears the option database. Default
276	options (from the
277	\fBRESOURCE_MANAGER\fR property or the \fB.Xdefaults\fR
278	file) will be reloaded automatically the next time an
279	option is added to the database or removed from it. This command
280	always returns an empty string.
281	.PP
282	The \fBoption get\fR command returns the value of the option
283	specified for \fIwindow\fR
284	under \fIname\fR and \fIclass\fR. If several entries in the option
285	database match \fIwindow\fR, \fIname\fR, and \fIclass\fR, then
286	the command returns whichever was created with highest
287	\fIpriority\fR level. If there are several matching
288	entries at the same priority level, then it returns whichever entry
289	was most recently entered into the option database. If there are
290	no matching entries, then the empty string is returned.
291	.PP
292	The \fBreadfile\fR form of the command reads \fIfileName\fR,
293	which should have the standard format for an
294	X resource database such as \fB.Xdefaults\fR, and adds all the
295	options specified in that file to the option database. If \fIpriority\fR
296	is specified, it indicates the priority level at which to enter the
297	options; \fIpriority\fR defaults to \fBinteractive\fR.
298	.PP
299	The \fIpriority\fR arguments to the \fBoption\fR command are
300	normally specified symbolically using one of the following values:
301	.TP
302	\fBwidgetDefault\fR
303	Level 20. Used for default values hard-coded into widgets.
304	.TP
305	\fBstartupFile\fR
306	Level 40. Used for options specified in application-specific
307	startup files.
308	.TP
309	\fBuserDefault\fR
310	Level 60. Used for options specified in user-specific defaults
311	files, such as \fB.Xdefaults\fR, resource databases loaded into
312	the X server, or user-specific startup files.
313	.TP
314	\fBinteractive\fR
315	Level 80. Used for options specified interactively after the application
316	starts running. If \fIpriority\fR isn't specified, it defaults to
317	this level.
318	.LP
319	Any of the above keywords may be abbreviated. In addition, priorities
320	may be specified numerically using integers between 0 and 100,
321	inclusive. The numeric form is probably a bad idea except for new priority
322	levels other than the ones given above.
323	.SH EXAMPLES
324	Instruct every button in the application to have red text on it unless
325	explicitly overridden:
326	.CS
327	\fBoption add\fR *button.foreground red startupFile
328	.CE
329	.PP
330	Allow users to control what happens in an entry widget when the Return
331	key is pressed by specifying a script in the option database and add a
332	default option for that which rings the bell:
333	.CS
334	entry .e
335	bind .e <Return> [\fBoption get\fR .e returnCommand Command]
336	\fBoption add\fR *.e.returnCommand bell widgetDefault
