 /*
  * Description:
  * This header can be used to register application on Symbian platforms
  * for the Camera capture button key events. Application can avoid native
  * camera application from starting by not forwarding the key event.
  *
  * Usage:
  * Application needs to include this header and include the needed Symbian
  * libraries. Optionally application can include camerakeyevent_symbian.pri
  * file. Application can register and unregister for the Camera capture
  * key events by creating/destructing the QSymbianCameraKeyListener helper
  * object. The widget needs to be shown before it registers for the
  * Camera key event.
  *
  * Libraries needed:
  * User needs to define following in the .pro file (or optionally include
  * the camerakeyevent_symbian.pri):
  * LIBS += -lcone -lws32
  *
  * Symbian Capabilities needed:
  * To use this header user needs to have SwEvent capability (included in
  * the camerakeyevent_symbian.pri):
  * TARGET.CAPABILITY += SwEvent
