Name: <STRONG>defaultRing</STRONG>
Class: <STRONG>DefaultRing</STRONG>
Command-Line Switch: <STRONG>-defaultring</STRONG>
Boolean describing whether the button displays its
default ring given in any of the forms acceptable to
<STRONG>Tcl_GetBoolean</STRONG>. The default is false.

<H2>DESCRIPTION</H2><PRE>
The <STRONG>pushbutton</STRONG> command creates a push button with an
optional default ring used for default designation and
traversal.
</PRE>
<H2>METHODS</H2><PRE>
The <STRONG>pushbutton</STRONG> command creates a new Tcl command whose name
is <EM>pathName</EM>. This command may be used to invoke various
operations 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. The following commands are possible for pushbutton
widgets:

<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
<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>pushbutton</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
corresponding 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>pushbutton</STRONG>
command.
