.SH DESCRIPTION
'
.PP
'
The \fBtixControl\fR command creates a new window (given by the
\fIpathName\fR 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 \fBSpinBox\fR 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.
'
'
'----------------------------------------------------------------------
.SH WIDGET COMMANDS
.PP
'
The \fBtixControl\fR command creates a new Tcl command whose name is
the same as the path name of the Control widget's window.  This
command may be used to invoke various operations on the widget. It has
the following general form:
'
.DS C
'
\fIpathName option \fR?\fIarg arg ...\fR?
.PP
.DE
'
\fIPathName\fR is the name of the command, which is the same as the
Control widget's path name.  \fIOption\fR and the \fIarg\fRs
determine the exact behavior of the command.  The following commands
are possible for Control widgets:
'
.TP
\fIpathName \fBcget\fR \fIoption\fR
'
Returns the current value of the configuration option given by
\fIoption\fR. \fIOption\fR may have any of the values accepted by the
\fBtixControl\fR command.
'
'
.TP
'
\fIpathName \fBconfigure\fR ?\fIoption\fR? \fI?value option value ...\fR?
'
Query or modify the configuration options of the widget.  If no
\fIoption\fR is specified, returns a list describing all of the
available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for
information on the format of this list).  If \fIoption\fR is specified
with no \fIvalue\fR, 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 \fIoption\fR is specified).  If
one or more \fIoption\-value\fR 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.  \fIOption\fR may have
any of the values accepted by the \fBtixControl\fR command.
'
.TP
\fIpathName \fBdecr\fR
'
Decrements the value of the Control widget by the step specified
by the \fI\-step\fR option.
'
'
.TP
\fIpathName \fBincr\fR
'
Increments the value of the Control widget by the step
specified by the \fI\-step\fR option.
'
'
.TP
\fIpathName \fBinvoke\fR
'
Causes the command specified by the \fI\-command\fR option to be
invoked.
'
.TP
\fIpathName \fBupdate\fR
'
If the user has modified the entry using keyboard inputs, the update
command will \fBupdate\fR the \fB\-value\fR of this Control
widget. When the Control widget's \fB\-selectmode\fR option is set to
"normal", one should call the \fBupdate\fR command on this widget
before examining its \fB\-value\fR option. This command has no effect
in if the \fB\-selectmode\fR option is set to "immediate".
'
.TP
\fIpathName \fBsubwidget \fI name ?args?\fR 
'
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.
'
'
'
'----------------------------------------------------------------------
.SH BINDINGS
.PP
'
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 \fB\-validatecmd\fR, \fB\-incrcmd\fR,
\fB\-decrcmd\fR, \fB\-step\fR, \fB\-max\fR and \fB\-min\fR options.
