have looked everywhere and got no assistance. is it possible to embed Google earth into a qt application? I am very new to qt and visual C++ in general. I got a sample that connected to Google maps. It works fine except I am unable to pan the map. can you please assist me. I know solutions are never given without my showing that I have tried and failed. I do not even know where to start. the code I have is below:

I basically want to to get on my desktop application what you get when you visit https://maps.google.com/

Qt Code:
