Camera {

id: camera

imageCapture {

onImageCaptured: panelsEntity.get(panelsEntity.currentIndex).pictureSource = preview

}

}

...

By setting panelsEntity.currentIndex to the delegate's index, we are keeping track of the currently selected (clicked) panel. After doing that, we tell the Camera object to capture an image via its imageCapture member object. We also add an empty pictureSource attribute to any element that we append to panelsEntity. Finally, we describe what should happen once the image has been captured. The image is available as preview, which is a temporary URL to the image data.

Here is the result, and it also works for any further panels that you add (however, do not overdo it; we haven't dealt with any memory concerns in this prototype!):
