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.
