\title QML Camera Example

|
\ingroup camera_examples_qml
|
|
|
|
\brief The Camera Example shows how to use the API to capture a still image
|
|
or video.
|
|
|
|
\image qml-camera.png
|
|
|
|
This example demonstrates the basic use of the Camera QML Plugin elements. The
|
|
plugin provides access to the API functionality for camera settings and
|
|
capturing an image.
|
|
|
|
Most of the QML code supports the user interface for this application with the
|
|
Camera elements being mostly found in \e {declarative-camera.qml} and
|
|
\e {CaptureControls.qml}.
|
|
|
|
In \e {declarative-camera.qml} the Camera element is initialized with an id
|
|
of \e {camera}, a photo preview is setup, states are implemented for image
|
|
preview or capture and a CaptureControls element is initialized. The initial
|
|
\e state is \e PhotoCapture. The camera element 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 PhotoPreview
|
|
element now becomes visible with any key press being picked up by the handler
|
|
in PhotoPreview and returning the state to \e PhotoCapture.
|
|
|
|
The \e CaptureControls element, 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()}
|
