Name:   topics
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

Specifies the directory where help files are located.

Name:   closeCmd
Class:  CloseCmd
Command-Line Switch:    -closecmd

Specifies the tcl command to be executed when the close option is selected from the topics menu.

Name:   maxHistory
Class:  MaxHistory
Command-Line Switch:    -maxhistory

Specifies the maximum number of entries stored in the history list

Name:   beforelink
Class:  BeforeLink
Command-Line Switch:    -beforelink

Specifies a command to be eval'ed before a new link is displayed. The path of the 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.

Name:   afterlink
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.

The 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).

The 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:

activate	center	childsite	deactivate

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

pathName showtopic topic

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.
