[Solved]The meaning of the "preview" parameter from the example "declarative-camera"



  • @imageCapture {
    onImageCaptured: {
    photoPreview.source = preview //where are this parameter(preview) come from?
    stillControls.previewAvailable = true
    cameraUI.state = "PhotoPreview"
    }
    }@

    File "declarative-camera.qml", line 91

    These are part of the codes from the Qt5 example ""declarative-camera"
    Can't find the source of this parameter, where is it come from?
    The preview should be the image the camera captured



  • Because of signature is
    onImageCaptured(requestId, preview)
    so the preview is the parameter of the signal
