Key features of the S60 platform and device SDKs for web and WRT developers

Web Browser for S60
An implementation of the Web Browser for S60 in the S60 3rd Edition and later SDKs' emulator provides support for web development. Using the emulator’s connectivity features, web developers are able to test websites and web pages stored locally or on the internet.

Web widget development
The S60 3rd Edition, Feature Pack 2 and later versions of the SDK support the development of web widgets. An implementation of WRT enables developers to install and run web widgets in the emulator.

Command-line launching of web pages
The SDKs provide a command-line interface that enables web developers to launch web pages in the emulator’s Web Browser for S60. The command opens the emulator if it’s not already running. This enables developers to launch their web pages quickly, reducing the time required for testing.

JavaScript™ API
The Web Browser for S60 and WRT support JavaScript™ 1.5. Using JavaScript technology, developers can add dynamic features to their web pages and web widgets.

Service API
The S60 5th Edition SDK includes the Service API, available through JavaScript extensions, which enables widget developers to access information stored on S60 devices. The API provides access to:

• The application manager.
• Calendar records.
• Contacts records.
• Log information.
• SMS and MMS messaging.
• The media gallery.
• Device location.
• Landmarks.
• System information.
• Sensors.

Debugging
The Web Browser for S60 implementation that is included in the emulator supports the JavaScript console, which enables developers to direct JavaScript errors to a pop-up, a log, or both when debugging web widgets in S60 3rd Edition, Feature Pack 2 and later SDKs.

Browser Control API
The Browser Control API enables developers of C++ applications to display web pages from within their applications. The control provided by the API makes it feasible to write an application’s UI in HTML, enabling users to interact with the application through an embedded browser.

What example WRT applications are included in the S60 platform and device SDKs?

The following example applications are available in the S60 5th Edition SDK for Symbian OS:

• CalendarWidget, which demonstrates using the Service API to access data in the Calendar application.
• ContactWidget, which demonstrates using the Service API to access data in the Contacts application.
• Java™ Console, which demonstrates use of the JavaScript™ console for widget debugging. The widget opens the console options in the Web Browser for S60, enabling debugging output to be directed to the JavaScript console or a log file. The widget includes a script that contains errors and can be run to demonstrate debugging output.
• LocationWidget, which demonstrates using the Service API to access a device’s location.
• LoggingWidget, which demonstrates using the Service API to access device log information.
• MediaManagementWidget, which demonstrates using the Service API to access media gallery items.
• MessagingWidget, which demonstrates using the Service API to access SMS and MMS messages.
• SensorWidget, which demonstrates using the Service API to access sensor information.

In addition, the Nokia N97 SDK includes Stew, a widget that illustrates how to add the display of a widget to the home screen of the Nokia N97 mobile computer.

For details of the example applications in other versions of the S60 SDKs, please refer to the release notes available on the download pages.

What WRT documentation is delivered in the S60 platform and device SDKs?

The S60 5th Edition SDK for Symbian OS includes the S60 5th Edition SDK guide and Web Developer’s Library 1.3.

For details of documentation in other versions of the S60 SDKs, please refer to the release notes available on the download pages.
