NAME
       tixSelect - Create and manipulate tixSelect widgets

SYNOPSIS
       tixSelect pathName ?options?

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

STANDARD OPTIONS
       The Select 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
       [-allowzero allowZero]  A boolean value that specifies whether the selection can be empty.
       When set to false, at least one button subwidget must be selected at any time.

       Note: When the Select widget is first constructed, the default selection is always  empty,
       even  if  -allowzero  is set to false.  [-buttontype buttonType] The type of buttons to be
       used as subwidgets inside the Select widget.  By default, the standard  Tk  button  widget
       class  is  used.   [-command command]  Specifies  the  TCL command to be executed when the
       -value of the Select widget is changed. This command will be invoked with  two  arguments.
       The  first  is  the name of the button subwidget that has toggled. The second is a boolean
       value indicating whether the button subwidget is selected. This command is  executed  only
       when  the  -disableCallback  option is set to false.  [-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 Select
       widget changes.

       Name:	      orientation
       Class:	      Orientation
       Switch:	      -orientation
       Alias:	      -orient

	      Specifies the orientation of the button subwidgets. Only the values horizontal  and
	      vertical are recognized. This is a static option and it can only be assigned during
	      the creation of the widget.  [-label label] Specifies the string to display as  the
	      label  of  this  Select  widget.	 [-labelside labelSide] Specifies where the label
	      should be displayed relative to the Select widget. Valid options	are:  top,  left,
	      right,  bottom,  none  or acrosstop.  [-padx padX] Specifies the horizontal padding
	      between two neighboring button subwidgets. This is a static option and it can  only
	      be assigned during the creation of the widget.  [-padx padY] Specifies the vertical
	      padding between two neighboring button subwidgets. This is a static option  and  it
	      can  only  be assigned during the creation of the widget.  [-radio radio] A boolean
	      value that specifies whether the Select widget should act as a radio-box. When  set
	      to true, at most one button subwidget can be selected at any time. This is a static
	      option and it can only be assigned during the creation of  the  widget.	[-select-
	      edbg selectedBg]	Specifies the background color of all the selected button subwid-
	      gets.  [-state state] Specifies the state of all the buttons inside the Select wid-
	      get.   Only the values normal and disabled are recognized. When the state is set to
	      disabled, all user actions on this Select widget are  ignore.   [-validatecmd vali-
	      dateCmd]	Specifies a TCL command to be called when the -value of the Select widget
	      is about to change. This command is called with one parameter  --  the  new  -value
	      entered  by  the	user.  This  command is to validate this new value by returning a
	      value it deems valid.  [-value value] The value of a Select widget is a list of the
	      names of the button subwidgets that have been selected by the user.

	      When  you assign the value of a Select widget using the "config -value" widget com-
	      mand, the TCL command specified by the -command option will be invoked if some but-
	      ton  subwidgets are toggled.  [-variable variable] Specifies the global variable in
	      which the value of the Select widget should be stored. The value of a Select widget
	      is  stored  as a list of the names of the button subwidgets that have been selected
	      by the user. The value of the Select widget will be automatically updated when this
	      variable is changed.

SUBWIDGETS
       Name:	      label
       Class:	      Label

	      The label subwidget.

       In  addition,  all the button subwidgets created as a result of the add widget command can
       be accessed by the subwidget command. They are identified by the buttonName  parameter  to
       the add widget command. Here is an example:

	      set s [tixSelect .s]
	      pack $s
	      $s add eat   -text Eat
	      $s add sleep -text Sleep
	      $s subwidget eat	 config -fg green
	      $s subwidget sleep config -fg red

DESCRIPTION
       The  tixSelect  command creates a new window (given by the pathName argument) and makes it
       into a Select widget.  Additional options, described above, may be specified on	the  com-
       mand  line or in the option database to configure aspects of the Select widget such as its
       cursor and relief.

       The Select widget is a container of button subwidgets. It can be used to provide radio-box
       or check-box style of selection options for the user.

WIDGET COMMANDS
       The tixSelect command creates a new Tcl command whose name is the same as the path name of
       the Select 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 Select widget's path name.
       Option and the args determine the exact behavior of the command.  The  following  commands
       are possible for Select widgets:

       pathName add buttonName ?option value ... ?
	      Adds  a new button subwidget with the name buttonName into the Select widget. Addi-
	      tional configuration options can be given to configure the new button subwidget.

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

       pathName invoke buttonName
	      Invokes the button subwidget with the name buttonName.

       pathName subwidget name ?args?
	      When  no	options are given, 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 left mouse button over the a button subwidget, it will be tog-
       gled and the -value option of the tixSelect widget will be changed.

EXAMPLE
       The following example creates a radio-box style iconbar for the user to choose  one  value
       among eat, work or sleep.

	      set s [tixSelect .s -radio true -allowzero false]
	      $s add eat   -bitmap [tix getbitmap eat]
	      $s add work  -bitmap [tix getbitmap work]
	      $s add sleep -bitmap [tix getbitmap sleep]
