# GimpUi.HelpFunc

    function onHelpFunc(help_id: String, help_data: void): void {
    }

This is the prototype for all functions you pass as @help_func to the various GIMP dialog constructors like GimpUi.Dialog.new, GimpUi.query_int_box etc.

Help IDs are textual identifiers the help system uses to figure which page to display.

All these dialog constructors functions call GimpUi.help_connect.

In most cases it will be ok to use GimpUi.standard_help_func which does nothing but passing the help_id string to Gimp.help. If your plug-in needs some more sophisticated help handling you can provide your own @help_func which has to call Gimp.help to actually display the help.

help_id

  the help ID

help_data

  the help user data
