Pressing the camera shutter key on the device halfway down generates additional -key events. The key events can be used to activate autofocus if the camera -hardware supports the functionality. Shutter release (image capture) can be -triggered by pressing the key all the way down. The key presses generate separate -key events. To capture other than autofocus key events from the shutter key, -you need the SwEvent capability.

The settings you can use in your application depend on the camera hardware -on the device. The Camera API allows you to query almost all features of the -device camera. For example, to get a list of supported advanced settings, -use the CCameraAdvancedSettings::GetSupportedSettingsL() method.

For more information on how to easily use the device camera with zoom and -autofocus by using a CameraWrapper made by Forum Nokia, see Camera Example on Forum Nokia. The Camera Wrapper -provides a unified interface for various Symbian camera APIs. The example -application supports the use of both the keypad and touch UI. The application -can be self-signed, but it also provides an option to use the dedicated camera -key (Symbian signing required).
