WIDGET-SPECIFIC OPTIONS

       Class:  Topics
       Command-Line Switch:    -topics

              Specifies  a  list of help topics in the form {?topic? ... }. Topic may either be a
              topic name, in which case the document associated with the topic should be  in  the
              file  helpdir/topic.html, or it may be of the form {name file}. In the latter case,
              name is displayed in the topic menu, and selecting the name loads file. If file has
              a relative path, it is assumed to be relative to helpdir.

       Name:   helpdir
       Class:  Directory
       Command-Line Switch:    -helpdir

              link  to be displayed is appended before evaling the command. A suggested use might
              be to busy the widget while a new page is being displayed.

       Class:  AfterLink
       Command-Line Switch:    -afterlink

              Specifies a command to be eval'ed after a new link is  completely  displayed.   The
              path of the link that was displayed is appended before evaling the command.

DESCRIPTION

       The iwidgets::hyperhelp command creates a shell window with a pulldown menu showing a list
       of  topics.  The  topics  are  displayed  by  importing  a  HTML  formatted   file   named
       helpdir/topic.html. For a list of supported HTML tags, see scrolledhtml(n).

METHODS

       The  iwidgets::hyperhelp  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.  The following commands are possible for dialog widgets:

INHERITED METHODS

       See the "shell" manual entry for details on the above inherited methods.

WIDGET-SPECIFIC METHODS

       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::hyperhelp 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::hyperhelp command.

       pathName showtopic topic
              Display  html  file  helpdir/topic.html.  Topic  may  optionally  be  of  the  form
              topicname#anchorname. In this form, either topicname or anchorname or both  may  be
              empty. If topicname is empty, the current topic is assumed. If anchorname is empty,
              the top of the document is assumed

       pathName followlink href
              Display html file href. Href may be optionally be of the form  filename#anchorname.
              In  this  form,  either filename or anchorname or both may be empty. If filename is
              empty, the current document is assumed. If anchorname is  empty,  the  top  of  the
              document is assumed.

       pathName forward
              Display html file one forward in history list, if applicable.

       pathName back
              Display html file one back in history list, if applicable.
