</pre><H3>DESCRIPTION</H3>

<P>

The <B>tixControl</B></I> command creates a new window (given by the

<I>pathName</I></B> argument) and makes it into a Control widget.

Additional options, described above, may be specified on the command

line or in the option database to configure aspects of the

Control widget such as its cursor and relief.

The Control widget is also known as the <B>SpinBox</B></I> widget.

It is generally used to control a value. The user can adjust the value

by pressing the two arrow buttons or by entering the value directly

into the entry. The new value will be checked against the user-defined

upper and lower limits.

</pre><H3>WIDGET COMMANDS</H3>

<P>

The <B>tixControl</B></I> command creates a new Tcl command whose name is

command may be used to invoke various operations on the widget. It has

the following general form:

<pre>

<I>pathName option </I></B>?<I>arg arg ...</I></B>?

<P>

</pre>

<I>PathName</I></B> is the name of the command, which is the same as the

determine the exact behavior of the command.  The following commands

are possible for Control widgets:

<DL>

<DT> <I>pathName <B>cget</B></I> <I>option</I></B>

</I></B>

<DD> Returns the current value of the configuration option given by

<I>option</I></B>. <I>Option</I></B> may have any of the values accepted by the

<B>tixControl</B></I> command.

</DL>

<DL>

<DT> <I>pathName <B>configure</B></I> ?<I>option</I></B>? <I>?value option value ...</I></B>?

</I></B>

<DD> Query or modify the configuration options of the widget.  If no

<I>option</I></B> is specified, returns a list describing all of the

available options for <I>pathName</I></B> (see <B>Tk_ConfigureInfo</B></I> for

information on the format of this list).  If <I>option</I></B> is specified

with no <I>value</I></B>, 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 <I>option</I></B> is specified).  If

one or more <I>option-value</I></B> 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.  <I>Option</I></B> may have

any of the values accepted by the <B>tixControl</B></I> command.

</DL>

<DL>

<DT> <I>pathName <B>decr</B></I>

</I></B>

<DD> Decrements the value of the Control widget by the step specified

by the <I>-step</I></B> option.

</DL>

<DL>

<DT> <I>pathName <B>incr</B></I>

</I></B>

<DD> Increments the value of the Control widget by the step

specified by the <I>-step</I></B> option.

</DL>

<DL>

<DT> <I>pathName <B>invoke</B></I>

</I></B>

<DD> Causes the command specified by the <I>-command</I></B> option to be

invoked.

</DL>

<DL>

<DT> <I>pathName <B>update</B></I>

</I></B>

<DD> If the user has modified the entry using keyboard inputs, the update

command will <B>update</B></I> the <B>-value</B></I> of this Control

"normal", one should call the <B>update</B></I> command on this widget

before examining its <B>-value</B></I> option. This command has no effect

in if the <B>-selectmode</B></I> option is set to "immediate".

</DL>

<DL>

<DT> <I>pathName <B>subwidget <I> name ?args?</I></B>

</I></B>

<DD> When no options are given, this command returns the pathname of the

subwidget of the specified name.

When options are given, the widget command of the specified subwidget

will be called with these options.

</DL>

</pre><H3>BINDINGS</H3>

<P>

When the user presses the up/down arrow buttons (or press the <Up> and

<Down> arrow keys on the keyboard), the value of the tixControl widget

is adjusted according to the <B>-validatecmd</B></I>, <B>-incrcmd</B></I>,

<B>-decrcmd</B></I>, <B>-step</B></I>, <B>-max</B></I> and <B>-min</B></I> options.
