Class XbpHelpLabel() Foundation
Class function of the XbpHelpLabel class.
The XbpHelpLabel class provides objects that are used to construct context sensitive help. XbpHelpLabel objects contain all the information required to display a specific help window within the online help. Each Xbase Part that is derived from XbpWindow() includes the :helpLinkinstance variable. This instance variable is used to reference an XbpHelpLabel object containing specific information about the Xbase Part.
The online help itself is managed by objects of the XbpHelp class. An XbpHelp object must be assigned to each XbpHelpLabel object in its :helpObject instance variable. This allows the help windows in the online help to be correctly displayed. In some cases it is sufficient for an XbpHelpLabel object (along with the XbpHelp object it references) to be assigned to the application window. The online help is then activated when the F1 key is pressed by the user. In this case, no context sensitive help is available. To provide context sensitive help, an XbpHelpLabel object must be assigned to each Xbase Part that has corresponding help text in the online help.
