NAME
       tixControl - Create and manipulate tixControl widgets

SYNOPSIS
       tixControl pathName ?options?

SUPER-CLASS
       The  TixControl	class  is derived from the TixLabelWidget class and inherits all the com-
       mands, options and subwidgets of its super-class.

STANDARD OPTIONS
       The Control widget supports all the standard options of a frame widget. See the options(n)
       manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS
       [-allowempty allowEmpty]  Specifies  whether  the  Control  widget  should allow the empty
       string as a valid input.  [-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.  [-command com-
       mand] Specifies the command to be called when the -value option of the Control  widget  is
       changed.   The  command	will be called with one arguments -- the new value of the Control
       widget.	[-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
       -value 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 -value of this Control widget.  [-disablecallback disableCallback] A
       boolean	value  indicating whether callbacks should be disabled. When set to true, the TCL
       command specified by the -command option is not executed when the -value  of  the  Control
       widget changes.	[-disableforeground disableForeground] The foreground color to use for of
       the entry subwidget when the Control widget is disabled.  [-incrcmd incrCmd]  Specifies	a
       TCL  command  to  be  called when the the user presses the up-arrow button subwidget. This
       command is called with one parameter -- the current -value of this  Control  widget.  This
       command is to increment this value by one step, according to its own definition of "incre-
       ment", and return the incremented value, which will be stored in the -value of  this  Con-
       trol  widget.  [-initwait initwait] Specifies how long the Control widget should wait ini-
       tially before it starts to automatically increment or decrement its value in  the  autore-
       peat  mode.  In	milliseconds.  [-integer integer] A Boolean value specifying whether only
       integer numbers are accepted.  [-label label] Specifies the string to display as the label
       of  this  Control widget.  [-labelside labelSide] Specifies where the label should be dis-
       played relative to the entry subwidget. Valid options are: top, left, right, bottom,  none
       or acrosstop.

       Name:	      max
       Class:	      Max
       Switch:	      -max
       Alias:	      -ulimit

	      Specifies  the  upper  limit  of the value of the Control widget. When set to empty
	      string, the Control widget has no upper limit.

       Name:	      min
       Class:	      Min
       Switch:	      -min
       Alias:	      -llimit

	      Specifies the lower limit of the value of the  Control  widget.When  set	to  empty
	      string,  the Control widget has no lower limit.  [-repeatrate repeatRate] Specifies
	      how often the value of the Control widget should be incremented or decremented when
	      it  is in the autorepeat mode. In milliseconds.  [-selectmode selectMode] Specifies
	      how the Control widget should react to <KeyPress> events. When set to  "immediate",
	      any  user  keyboard  inputs  will immediately change the -value option. When set to
	      "normal", the user keyboard inputs will be copied to the -value option only if  the
	      <Return>	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 update widget command (see below).  [-state state]
	      Specifies the whether the Control widget is normal or disabled.	Only  the  values
	      "normal"	and  "disabled"  are  recognized.  [-step step] Specifies by how much the
	      value of the Control widget should be incremented or decrmented when the user press
	      the arrow buttons.  [-validatecmd validateCmd] 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 -value entered by the user. This command is to vali-
	      date this new value by returning a value it deems valid.	[-value value]	Specifies
	      the  value  of the Control widget.  [-variable variable] Specifies the global vari-
	      able in which the value of the Control widget should be stored. The  value  of  the
	      Control widget will be automatically updated when this variable is changed.

DESCRIPTION
       The  tixControl command creates a new window (given by the pathName argument) and makes it
       into a Control widget.  Additional options, described above, may be specified on the  com-
       mand 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 SpinBox 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.

WIDGET COMMANDS
       The  tixControl	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:
		     pathName option ?arg arg ...?
       PathName  is the name of the command, which is the same as the Control widget's path name.
       Option and the args determine the exact behavior of the command.  The  following  commands
       are possible for Control widgets:

       pathName cget option
	      Returns  the  current value of the configuration option given by option. Option may
	      have any of the values accepted by the tixControl command.

       pathName configure ?option? ?value option value ...?
	      Query or modify the configuration options of the widget.	If no  option  is  speci-
	      fied,  returns  a  list  describing  all of the available options for pathName (see
	      Tk_ConfigureInfo for information on the format of this list).  If option is  speci-
	      fied with no value, 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 option is specified).	If one or more option-value 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.	Option may have any of the values
	      accepted by the tixControl command.

       pathName decr
	      Decrements the value of the Control widget by  the  step	specified  by  the  -step
	      option.

       pathName incr
	      Increments  the  value  of  the  Control	widget by the step specified by the -step
	      option.

       pathName invoke
	      Causes the command specified by the -command option to be invoked.

       pathName update
	      If the user has modified the entry using keyboard inputs, the update  command  will
	      update  the  -value  of  this Control widget. When the Control widget's -selectmode
	      option is set to "normal", one should call the update command on this widget before
	      examining  its  -value  option.  This  command  has no effect in if the -selectmode
	      option is set to "immediate".

       pathName subwidget  name ?args?
	      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.

BINDINGS
       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 -vali-
       datecmd, -incrcmd, -decrcmd, -step, -max and -min options.
