Detailed Description
The QCameraFlashControl class allows controlling a camera's flash.
You can set the type of flash effect used when an image is captured, and test to see if the flash hardware is ready to fire.
You can retrieve this control from the camera object in the usual way:
Some camera devices may not have flash hardware, or may not be configurable. In that case, there will be no QCameraFlashControl available.
The interface name of QCameraFlashControl is org.qt-project.qt.cameraflashcontrol/5.0
as defined in QCameraFlashControl_iid.
See also QCamera.
