I try to create an assistant program (“wizard”) to visually arrange the printable areas of a document.
Therefor I load a PDF file and display it in Quicklook (QLPreviewControlMBS). Next I would like to instantiate canvases, put it on top of the quicklook and draw something.
Unfortunately the QLPreviewControlMBS stays in frontmost position and hides the canvases.
1.) Is there a way to put it behind a canvas?
2.) What other options would I have to display a pdf and draw on top of it?
