It has a user interface, -control functions, setting values and a means of defining the location where -the image or video clip is to be saved. It will also store the image and video -settings. - -The Camera class contains an instance of \l {QCamera}, the API class interface to -the hardware. It also has an instance of \l {QCameraImageCapture} to take still images -and an instance of \l {QMediaRecorder} to record video. It also contains the user -interface object. - -The Camera constructor does some basic initialization. The camera object is -set to '0', the user interface is initialized and UI signal are connected to -slots that react to the triggering event. However, most of the work is done when -the \i {setCamera()} function is called, passing in a \l {QByteArray}. - -\i {setCamera()} sets up various connections between the user interface and the functionality -of the Camera class using signals and slots. It also instantiates and initializes the \l {QCamera}, -\l {QCameraImageCapture} and \l {QMediaRecorder} objects mentioned above. The still -and video recording visual tabs are enabled and finally the -\l {QCamera::start()}{start()} function of the \l{QCamera} object is called. - -Now that the camera is ready for user commands it waits for a suitable event. -Such an event will be the key press of either the \l {Qt::Key_CameraFocus} or -\l {Qt::Key_Camera} buttons on the application window. Camera focus will -simply display the viewfinder and lock the camera settings. Key_Camera will -either call \i {takeImage()} if the \l {QCamera::captureMode()}{captureMode()} -is QCamera::CaptureStillImage, or if the capture mode is for video then one -of two actions will occur. If the recording state shows that we are currently -recording then the \i {stop()} function is called resulting in a call to -\l {QCamera::stop()}, whereas if we are not recording then a video recording -is started with a call to \l {QMediaRecorder::record()}. - -\image camera-example.png - -*/ - - |
