Content management and navigation skills in Javahelp API

The Javahelp API is a scalable help system on the Java platform.It provides the ability of developers to integrate help documents in applications.Javahelp API provides content management and navigation skills, and users can highly browse and search for help documents.This article will introduce some content management and navigation skills in the Javahelp API, and provide some Java code examples. ### Content management skills 1. HTML formatting: Javahelp API supports the help content in HTML format.Developers can use HTML tags and styles to create help documents and integrate them into applications through the Javahelp API.The following is a simple example, demonstrating how to display a HTML page in Javahelp: HelpSet helpSet = new HelpSet(getClass().getClassLoader(), helpsetURL); HelpBroker helpBroker = helpSet.createHelpBroker(); helpBroker.setCurrentID("helpPage.html"); helpBroker.setDisplayed(true); 2. Create a help theme: You can use the JavahelP API to create different help themes and organize it to help the collection.Developers can create multiple help pages for each theme and organize in the help set.The following is an example that shows how to create a help theme and add multiple help pages: DefaultMutableTreenode rootNode = New DefaultMutabletreenode ("Help File"); DefaultMutableTreeNode topicNode = new DefaultMutableTreeNode("主题"); DefaultMutableTreenode PageNode = New DefaultMutabletreenode ("Help Page"); topicNode.add(pageNode); rootNode.add(topicNode); DefaultHelpModel helpModel = new DefaultHelpModel(rootNode); 3. Multi -language support: Javahelp API provides a function of multi -language support.Developers can load the corresponding help documents according to the user's language environment to provide localized help content.The following is an example, which demonstrates how to load different help documents according to the user's language environment: Locale userLocale = Locale.getDefault(); URL helpsetURL = getClass().getResource("Help_" + userLocale.getLanguage() + ".hs"); HelpSet helpSet = new HelpSet(getClass().getClassLoader(), helpsetURL); ### navigation skills 1. Search function: Javahelp API provides search function, and users can quickly find keywords or phrases in the help content.Developers can add indexes to help documents and use search methods provided by the Javahelp API to perform search operations.The following is an example that demonstrates how to perform search operations in Javahelp: HelpSet helpSet = new HelpSet(getClass().getClassLoader(), helpsetURL); HelpBroker helpBroker = helpSet.createHelpBroker(); helpBroker.enableHelpKey(window, "mainWindow", helpSet); helpBroker.enableHelpOnButton(button, "buttonHelp", helpSet); SearchTOC searchTOC = helpBroker.getSearchTOC(); searchtoc.search ("keyword"); 2. Context -related help: Javahelp API supports the help of context -related help. Users can directly access the help content related to the current application status.Developers can set the context related help for each application window or component.The following is an example that demonstrates how to achieve context -related help in Javahelp: HelpSet helpSet = new HelpSet(getClass().getClassLoader(), helpsetURL); HelpBroker helpBroker = helpSet.createHelpBroker(); helpBroker.enableHelpKey(window, "windowHelp", helpSet); helpBroker.enableHelpOnButton(button, "buttonHelp", helpSet); 3. Dynamic help: Javahelp API supports dynamic help, that is, the help content can change according to the state of the application or the operation of the user.Developers can use the method provided by the Javahelp API to update to help documents and help gatherings during runtime.The following is an example that demonstrates how to achieve dynamic help in Javahelp: HelpSet helpSet = new HelpSet(getClass().getClassLoader(), helpsetURL); HelpBroker helpBroker = helpSet.createHelpBroker(); helpBroker.setCurrentID("defaultPage.html"); helpBroker.setDisplayed(true); // Update the help content when running helpBroker.setCurrentID("newPage.html"); By using the content management and navigation techniques in the Javahelp API, developers can provide a powerful help system for their applications.This allows users to easily browse and search for help documents and quickly obtain the required help information.Hope this article will help you!
