  4. Widgets • Conform to proposed W3C widget standard • Based on HTML, JavaScript, CSS • Can use XMLHttpRequest or XMLDOM • Packaged in .zip format (with .wgt extension) • To develop you’ll need the Windows Mobile 6.5 Developer Toolkit (has emulator images)

  5. Manifest (config.xml) Mandatory file • <widget> - Root element • <access> - Network requirements • <content> - required - src attribute links to start file • <description> - um…. • <icon> - A .PNG for touch screen devices

  6. widget manifest (continued) Example: • <?xml version="1.0" encoding="utf-8" ?> • <widget version="1.0.0.0" xmlns="http://www.w3.org/ns/widgets"> • <name>GeekzoneFriends</name> • <content src="startup.htm" type="text/html" /> • <access network="true" /> • <icon src="gzf90.png"/> • <icon src="gzf.ico"/> • <author email="kevindaly@xtra.co.nz" /> • <description>Geekzone status updates</description> • </widget>

  7. JavaScript objects: widget Exposes useful properties and methods e.g. • widget.authorEmail • widget.authorName • widget.menu – the widget’s menu • Also authorURL, currentIcon, description, height, identifier, locale, name, version, width

  8. widget object (continued) • Also exposes persistence methods: • widget.preferenceForKey(key) • widget.setPreferenceForKey(<value>, key);

  9. SystemState object • CradlePresent • DisplayRotation • PhoneHomeService • PhoneOperatorName • PhoneRoaming • PhoneSignalStrength • PowerBatteryState • PowerBatteryStrength

  10. SystemState (continued) Example (from MSDN): varcradledState = systemState.CradlePresent; cradledState.addEventHandler("changed", cradled);
