<H2>DESCRIPTION</H2><PRE>
The <STRONG>radiobox</STRONG> command creates a radio button box widget capa-
ble of adding, inserting, deleting, selecting, and configur-
ing radiobuttons as well as obtaining the currently selected
button.
</PRE>
<H2>METHODS</H2><PRE>
The <STRONG>radiobox</STRONG> command creates a new Tcl command whose name is
<EM>pathName</EM>. This command may be used to invoke various opera-
tions on the widget. It has the following general form:
<EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
<EM>Option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
mand.
Many of the widget commands for the <STRONG>radiobox</STRONG> take as one
argument an indicator of which radiobutton of the radiobox
to operate on. These indicators are called <EM>indexes</EM> and
allow reference and manipulation of radiobuttons. Radiobox
indexes may be specified in any of the following forms:
<EM>number</EM> Specifies the radiobutton numerically, where 0
corresponds to the top radiobutton of the
radiobox.
<STRONG>end</STRONG> Indicates the last radiobutton of the radiobox.
<EM>pattern</EM> If the index doesn't satisfy one of the above
forms then this form is used. <EM>Pattern</EM> is
pattern-matched against the tag of each
radiobutton in the radiobox, in order from top
to bottom, until a matching entry is found. The
rules of <STRONG>Tcl_StringMatch</STRONG> are used.
</PRE>
<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
<EM>pathName</EM> <STRONG>add</STRONG> <EM>tag</EM> ?<EM>option</EM> <EM>value</EM> <EM>option</EM> <EM>value</EM>?
Adds a new radiobutton to the radiobuttond window on
the bottom. The command takes additional options which
are passed on to the radiobutton as construction argu-
ments. These include the standard Tk radiobutton
options. The tag is returned.
<EM>pathName</EM> <STRONG>buttonconfigure</STRONG> <EM>index</EM> ?<EM>options</EM>?
This command is similar to the <STRONG>configure</STRONG> command,
except that it applies to the options for an individual
radiobutton, whereas <STRONG>configure</STRONG>applies to the options
for the radiobox as a whole. <EM>Options</EM> may have any of
the values accepted by the <STRONG>add</STRONG> widget command. If
<EM>options</EM> are specified, options are modified as indi-
cated in the command and the command returns an empty
string. If no <EM>options</EM> are specified, returns a list
describing the current options for entry <EM>index</EM> (see
<STRONG>Tk_ConfigureInfo</STRONG> for information on the format of this
list).
<EM>pathName</EM> <STRONG>cget</STRONG> <EM>option</EM>
Returns the current value of the configuration option
given by <EM>option</EM>. <EM>Option</EM> may have any of the values
accepted by the <STRONG>radiobox</STRONG> command.
<EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
Query or modify the configuration options of the
widget. If no <EM>option</EM> is specified, returns a list
describing all of the available options for <EM>pathName</EM>
(see <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
this list). If <EM>option</EM> is specified with no <EM>value</EM>, then
the command returns a list describing the one named
option (this list will be identical to the correspond-
ing sublist of the value returned if no <EM>option</EM> is
specified). If one or more <EM>option</EM> - <EM>value</EM> pairs are
specified, then the command modifies the given widget
option(s) to have the given value(s); in this case the
command returns an empty string. <EM>Option</EM> may have any
of the values accepted by the <STRONG>radiobox</STRONG> command.
<EM>pathName</EM> <STRONG>delete</STRONG> <EM>index</EM>
Deletes a specified radiobutton given an <EM>index</EM>.
<EM>pathName</EM> <STRONG>deselect</STRONG> <EM>index</EM>
Deselects a specified radiobutton given an <EM>index</EM>.
<EM>pathName</EM> <STRONG>flash</STRONG> <EM>index</EM>
Flashes a specified radiobutton given an <EM>index</EM>.
<EM>pathName</EM> <STRONG>get</STRONG>
Returns the tag of the currently selected radiobutton.
<EM>pathName</EM> <STRONG>index</STRONG> <EM>index</EM>
Returns the numerical index corresponding to index.
<EM>pathName</EM> <STRONG>insert</STRONG> <EM>index</EM> <EM>tag</EM> ?<EM>option</EM> <EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
Same as the <STRONG>add</STRONG> command except that it inserts the new
radiobutton just before the one given by <EM>index</EM>, instead
of appending to the end of the radiobox. The <EM>option</EM>,
and <EM>value</EM> arguments have the same interpretation as for
the <STRONG>add</STRONG> widget command.
<EM>pathName</EM> <STRONG>select</STRONG> <EM>index</EM>
Selects a specified radiobutton given an <EM>index</EM>.
