Caveat: This is not going to be the answer you are looking for.

Are you sure you want this? To what end? Is this about writing a QPaintDevice based on Cairo? Qt has its own graphics primitives implemented and so does Cairo. The only reason I can see is that you don't want the a heavy layer of Qt interfere with your system (embedded?). It's like you are trying to use the DirectFB backend of Cairo -- but then there's stuff like Qt-on-DirectFB. However, note such an implementation is costly and not free without its own set of quarks such as library-interop issues, printing from this Cairo based context etc. I'd suggest you do a regular search on Google to figure if such efforts are/ever were underway and weigh the pros and cons very heavily before even attempting the same.
