contents of the widget may still be selected. If the Spinbox is
disabled, the value may not be changed, no insertion cursor will be
displayed, the contents will not be selectable, and the Spinbox may
be displayed in a different color, depending on the values of the

<p>Specifies the mode in which validation should operate: <strong>none</strong>,
<strong>focus</strong>, <strong>focusin</strong>, <strong>focusout</strong>, <strong>key</strong>, or <strong>all</strong>.
It defaults to <strong>none</strong>. When you want validation, you must explicitly
state which mode you wish to use. See <strong>Validation</strong> below for more.</p>

<dt><strong><a name="item_class_3a_validatecommand">Class: <strong>ValidateCommand</strong></a></strong>
<dd>
<p>Specifies a script to evaluate when you want to validate the input in the
widget. Setting it to an empty string disables this feature (the default).
Validation occurs according to the value of <strong>-validate</strong>.
This command must return a valid boolean value. If it returns 0 (or
the valid boolean equivalent) then the value of the widget will not
change and the <strong>invalidCommand</strong> will be evaluated if it is set. If it
returns 1, then value will be changed.
See <strong>Validation</strong> below for more information.</p>

<dt><strong><a name="item_name_3a_values">Name: <strong>values</strong></a></strong>
<dt><strong><a name="item_class_3a_values">Class: <strong>Values</strong></a></strong>
<dd>
<p>Must be a proper list value. If specified, the Spinbox will use these
values as to control its contents, starting with the first value. This
option has precedence over the <strong>-from</strong> and <strong>-to</strong> range.</p>
</dd>
</li>
<dt><strong><a name="item_option_3a__2dwidth">Option: <strong>-width</strong></a></strong>
<dt><strong><a name="item_name_3a_width">Name: <strong>width</strong></a></strong>
<dt><strong><a name="item_class_3a_width">Class: <strong>Width</strong></a></strong>
<dd>
<p>Specifies an integer value indicating the desired width of the Spinbox window,
in average-size characters of the widget's font.
If the value is less than or equal to zero, the widget picks a
size just large enough to hold its current text.</p>
</dd>
</li>
<dt><strong><a name="item_option_3a__2dwrap">Option: <strong>-wrap</strong></a></strong>
<dt><strong><a name="item_name_3a_wrap">Name: <strong>wrap</strong></a></strong>
<dt><strong><a name="item_class_3a_wrap">Class: <strong>Wrap</strong></a></strong>
<dd>
<p>Must be a proper boolean value. If on, the Spinbox will wrap around the
values of data in the widget.</p>
</dd>

<h1><a name="description">DESCRIPTION</a></h1>
<p>The <strong>Spinbox</strong> method creates a new window (given by the
$spinbox argument) and makes it into a Spinbox widget.
Additional options, described above, may be specified on the
command line or in the option database
to configure aspects of the Spinbox such as its colors, font,
and relief.</p>
<p>A <strong>Spinbox</strong> is an extended <strong>Entry</strong> widget that allows he user
to move, or spin, through a fixed set of ascending or descending values
such as times or dates in addition to editing the value as in an
<strong>entry</strong>. When first created, a Spinbox's string is empty.
A portion of the Spinbox may be selected as described below.
If a Spinbox is exporting its selection (see the <strong>exportSelection</strong>
option), then it will observe the standard protocols for handling the
selection; Spinbox selections are available as type <strong>STRING</strong>.
Spinboxes also observe the standard Tk rules for dealing with the
input focus. When a Spinbox has the input focus it displays an
<em>insertion cursor</em> to indicate where new characters will be
inserted.</p>
<p>Spinboxes are capable of displaying strings that are too long to
fit entirely within the widget's window. In this case, only a
portion of the string will be displayed; commands described below
may be used to change the view in the window. Spinboxes use
the standard <strong>-xscrollcommand</strong> mechanism for interacting with
scrollbars (see the description of the <strong>-xscrollcommand</strong> option
for details). They also support scanning, as described below.</p>
