NetFront 3. It is equivalent to reading and writing the value of the style attribute, so styles can only be read if they were set using that attribute. The syntax is simple. Simply write element. For example, background-color becomes backgroundColor.

Versions 5. However, the standard ICEbrowser does not support several features important for a full-featured help system. If you substitute a different HTML display component, these features will not work. Also, if you display your HTML topic files directly in a web browser, that browser will not recognize the protocols and metadata documented on this page; therefore these features will not work.

OHW does support these features. However, the process is different than in OHJ. An Oracle Help for the Web help system can be viewed in any current web browser, and those browsers do not directly support these conventions. The topicid protocol also supports anchor links.

When the user selects an associative link in a topic, a list of all topics associated with the link is displayed, and the user can choose a topic from the list. Oracle Help supports associative links through the Oracle Help alink protocol, along with the link file that specifies the associative links for the helpset.

The feature is particularly useful when link files from multiple helpsets are merged. You can handle such links in your application by registering a CustomProtocolHandler with your Help instance. Create an implementation of oracle.

CustomProtocolHandler and register it with your oracle. Help instance through the registerCustomProtocolHandler method. For the example link, you would register an instance of your CustomProtocolHandler using the string myProtocol as the first argument to the registerCustomProtocolHandler method. When Oracle Help for Java encounters custom protocol links, it searches for a CustomProtocolHandler registered with the Help object using the identifier myProtocol. If one is found, the handleValue String value method of the CustomProtocolHandler is invoked, passing myValue as the value.

Note: If you want to provide link to an external URL, you are not required to register a custom protocol handler. OHJ provides a registered custom protocol external for the same. For example, the following code creates a link that navigates to OTN page in the default internet browser instead of OHJ browser.

When the pop-up link is clicked, the contents of the file associated with the topic ID is displayed in a lightweight pop-up window. However, you can specify topic IDs in the topics file themselves and then use the Helpset Authoring Wizard to generate a map file from that information.

You can associate topics and topic IDs with these window types in the map file so that whenever the topic is displayed, it is displayed in the specified window. If you plan to use the Helpset Authoring Wizard, you can associate a window type with a topic in the topic file itself. Then the wizard uses the information from both META tags to generate the map file. Note: You do not have to use this method for associating topics with window types.

It may be easier to do it directly in the map file. Third-party authoring tools may use this META tag for associating topics with window types. This is no longer the case: the map file is now the central repository for this information.

By setting the engine attribute, one can use a custom engine to parse the map file and create an object used to map between topic IDs and files. In fact, by using certain engines, you may actually eliminate the map file altogether. However, Oracle Help supports two engines that support certain common conventions for mediating between topic IDs and files: oracle.

XMLMapConventionEngine If those two engines do not satisfy your needs for dynamic mapping, you can write a custom implementation of oracle. While using Oracle Help, setting the engine to this value makes your old map file expendable. However, if your help content may be viewed using an older version of Oracle Help, you should keep your old map file around so that the older versions of Oracle Help can fall back to the standard mechanism of topic mapping.

Doing so implies that your map file is never read, and therefore its contents are not stored in the memory. In addition, any subhelpsets must also reside in the same directory as the master helpset file. Subdirectories for subhelpsets are not permitted because the help system is not able to find your content unless it is in the same directory as the master helpset.

However, different helpsets may reside in different directories. By keeping this information in the map file, the author has one central repository for managing these assignments.

You simply specify how your topic IDs are structured. If the urlBase attribute was unspecified, it would be assumed that myfile. However, context sensitive help calls to specific topics may take a long time to resolve if your library includes many helpsets. Because of this, context sensitive help calls go through each helpset in the library and check whether the URLs generated by the engines actually resolve. In the worst case, for a single context sensitive help call, the help system attempts to connect to as many URLs as there are helpsets in your library.

However, Oracle Help provides a simple remedy to alleviate the problem. Failure to set engineParams does not break your help system, but performance will not be optimal.
