\fBtixControl \fIpathName \fR?\fIoptions\fR?
'\"
'\"
'\"----------------------------------------------------------------------
.SH SUPER-CLASS
The \fBTixControl\fR class is derived from the \fBTixLabelWidget\fR
class and inherits all the commands, options and subwidgets of its
super-class.
'\"
'\"----------------------------------------------------------------------
.SH "STANDARD OPTIONS"
'\"
The Control widget supports all the standard options of a frame
widget. See the \fBoptions(n)\fR manual entry for details on the
standard options.

Specifies whether the Control widget should allow the empty string
as a valid input.
'\"----------END
'\"
'\"----------BEGIN
.OP \-autorepeat autorepeat AutoRepeat
Specifies whether the Control widget should have autorepeat behavior.
If set to be "true", the value of the Control widget will be
automatically incremented or decremented when the user holds down the
mouse button over the arrow buttons. Only values "true" and
"false" will be recognized.
'\"----------END
'\"
'\"
'\"----------BEGIN
.OP \-command command Command
Specifies the command to be called when the \fB\-value\fR option of
the Control widget is changed. The command will be called with one
arguments -- the new value of the Control widget.
'\"----------END
'\"
'\"
'\"----------BEGIN
.OP \-decrcmd decrCmd DecrCmd
Specifies a TCL command to be called when the the user presses the
down-arrow button subwidget. This command is called with one parameter
-- the current \fB\-value\fR of this Control widget. This
command is to decrement this value by one step, according to its own
definition of "decrement", and return the decremented value, which
will be stored in the \fB\-value\fR of this Control widget.
'\"----------END
'\"
'\"----------BEGIN

Control widget is disabled.
'\"----------END
'\"
'\"

'\"----------BEGIN
.OP \-selectmode selectMode SelectMode
Specifies how the Control widget should react to \fC<KeyPress>\fR
events. When set to "immediate", any user keyboard inputs will
immediately change the \fB\-value\fR option. When set to "normal", the
user keyboard inputs will be copied to the \fB\-value\fR option only
if the\fC <Return>\fR key is pressed or the keyboard focus is
changed. The use of the immediate mode is discouraged. For effective
use of the Control widget, one should use the normal mode together
with the \fBupdate\fR widget command (see below).

Specifies the whether the Control widget is normal or
disabled. Only the values "normal" and "disabled" are recognized.

Specifies a TCL command to be called when the -value of the
Control widget is about to change. This command is called
with one parameter -- the new \fB\-value\fR entered by the user. This

valid.

.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:
'\"
.RS
.CS
'\"
\fIpathName option \fR?\fIarg arg ...\fR?
.CE
.RE
'\"
\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.
