This element is part of the \bold{QtMultimedia 5.0} module.
The CameraFlash element allows you to operate the camera flash
hardware and control the flash mode used. Not all cameras have
flash hardware (and in some cases it is shared with the
\l {Torch}{torch} hardware).
It should not be constructed separately but provided by the
Camera element's \l {Camera::flash}{flash} property.
