<H2>DESCRIPTION</H2><PRE>
The <STRONG>spinner</STRONG> command creates a spinner widget. The spinner
is comprised of an entryfield plus up and down arrow but-
tons. Arrows may be drawn horizontally or vertically.
</PRE>
<H2>METHODS</H2><PRE>
The <STRONG>spinner</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. The following commands are possible for spinner widg-
ets:

</PRE>
<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>spinner</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>spinner</STRONG> command.
<EM>pathName</EM> <STRONG>down</STRONG>
Derived classes may overload this method to specialize
functionality.
<EM>pathName</EM> <STRONG>up</STRONG>
Derived classes may overload this method to specialize
functionality.
