I’m finding that if I use
std::unique_ptr <CameraDevice> camDev;
I get a nice camera preview on MacOS and on iOS but I can not for the life of me get any other graphical component to be visually on top of it. Even the method
.setAlwaysOnTop(true) can’t put a graphical component above the preview.
My guess is this is because the preview is OS provided as some sort of an overlay.
My question is how would one place components above the camera preview eg like a HUD? Is there some aspect of the cameraPreview that I’m misunderstanding?
Many thanks in advance!
