DESCRIPTION

       The  iwidgets::checkbox  command  creates  a  check  button  box widget capable of adding,
       inserting, deleting, selecting, and configuring checkbuttons  as  well  as  obtaining  the
       currently selected button.

METHODS

       The  iwidgets::checkbox  command  creates  a new Tcl command whose name is pathName.  This
       command may be used to invoke various operations on the  widget.   It  has  the  following
       general  form:  pathName  option  ?arg  arg  ...?  Option and the args determine the exact
       behavior of the command.

       Many of the widget commands for the checkbox take as one argument an  indicator  of  which
       checkbutton  of the checkbox to operate on.  These indicators are called indexes and allow
       reference and manipulation of checkbuttons.  Checkbox indexes may be specified in  any  of
       the following forms:

       number      Specifies  the  checkbutton  numerically,  where  0  corresponds  to  the  top
                   checkbutton of the checkbox.

       end         Indicates the last checkbutton of the checkbox.

       pattern     If the index doesn't satisfy one of the above forms then this  form  is  used.
                   Pattern  is  pattern-matched  against  the  tag  of  each  checkbutton  in the
                   checkbox, in order from top to bottom, until a matching entry is  found.   The
                   rules of Tcl_StringMatch are used.

WIDGET-SPECIFIC METHODS

       pathName add tag ?option value option value?
              Adds a new checkbutton to the checkbuttond window on the bottom.  The command takes
              additional  options  which  are  passed  on  to  the  checkbutton  as  construction
              arguments.   These  include  the  standard  Tk  checkbutton  options.   The  tag is
              returned.

       pathName buttonconfigure index ?options?
              This command is similar to the configure command, except that  it  applies  to  the
              options  for an individual checkbutton, whereas configureapplies to the options for
              the checkbox as a whole.  Options may have any of the values accepted  by  the  add
              widget command.  If options are specified, options are modified as indicated in the
              command and the command returns an empty string.   If  no  options  are  specified,
              returns a list describing the current options for entry index (see Tk_ConfigureInfo
              for information on the format of this list).

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

       pathName configure ?option? ?value option value ...?
              Query  or  modify  the  configuration  options  of  the  widget.   If  no option is
              specified, 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
              specified 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 iwidgets::checkbox command.

       pathName delete index
              Deletes a specified checkbutton given an index.

       pathName deselect index
              Deselects a specified checkbutton given an index.

       pathName flash index
              Flashes a specified checkbutton given an index.

       pathName get ?index?
              Returns  the tags of the currently selected checkbuttons or the selection status of
              specific checkbutton when given an index.

       pathName index index
              Returns the numerical index corresponding to index.

       pathName insert index tag ?option value option value ...?
              Same as the add command except that it inserts the new checkbutton just before  the
              one  given  by index, instead of appending to the end of the checkbox.  The option,
              and value arguments have the same interpretation as for the add widget command.

       pathName select index
              Selects a specified checkbutton given an index.
