It shows how to change settings and to capture images. + +Most of the QML code supports the user interface for this application with the +camera types being mostly found in \e {declarative-camera.qml} and +\e {CaptureControls.qml}. + +In \e {declarative-camera.qml} the \l Camera is initialized with an id +of \e {camera}, a photo preview is setup, states are implemented for image +preview or capture and \l CaptureControls is initialized. The initial +\e state is \e PhotoCapture. \l CameraCapture includes a handler, \e onImageCaptured, +for the \l {imageCaptured} signal. The handler sets up the application to process +the preview including a change in the user interface state. The \l PhotoPreview +becomes visible with any key press being picked up by the handler +in PhotoPreview and returning the state to \e PhotoCapture. + +\e CaptureControls, which is implemented in \e {CaptureControls.qml}, +generates a column on the right hand side of the screen which includes control +buttons for \e focus (not initially visible), \e {capture}, \e {flash modes}, +\e {white balance}, \e {exposure compensation}, and if a preview is +available a \e {preview} button. The last button exits from the application. + +When the Capture button is pressed the \e onClicked handler calls +\l {Camera::captureImage()}{captureImage()} + + + + + + + +*/ |
