To develop a widget for a mobile device, you need:
Desktop computer that can be used to develop Web content
Text editor to create HTML, CSS, and JavaScript files
A text editor such as Notepad is sufficient for developing widgets. +However, you can also use a more advanced development tool. Web developers +can use the same tools that they have used for creating Web content.
Graphics program if you need to create images for your widget
ZIP utility such as WinZip to +create the widget installation package
Desktop Web browser, such as Mozilla +Firefox or Internet Explorer
Mobile device that can run widgets
Use a mobile device for testing your widget. To check +which mobile devices support widgets and the Web Runtime environment, see +section Web Runtime versions and device support.
Note: S60 3rd Edition, Feature Pack 2 only supports WRT 1.0. If you are developing +the widget for a newer WRT, make sure that your device runs an S60 platform +version that supports that WRT.
Note: To transfer your widget to a mobile device, you need a connection between +your PC and your mobile device. USB cables and Bluetooth connection are commonly +used for this purpose, but the suitable connection type depends on the mobile +device and PC. Check the documentation of your mobile device for information +on how to make these connections. One typical method is to use the version +of Nokia PC Suite that +is compatible with your mobile device.
In addition to a mobile device, you can also view and test your widget +with the device emulator included in the S60 C++ SDK package. The SDK is available +for download from Forum +Nokia. To successfully install the SDK, you need to have Microsoft +Windows XP SP2 or later with ActivePerl 5.6.1.x running on your computer. +Check the Installation Guide provided with the SDK for the precise software +requirements.
