Yes, that looks fine, the generated code should add includes like '#include 
<kcanvas/KCanvas.h>' now.

That looks fine.

I remove the duplicates and have everything under kcanvas and kcanvas/device. 
Do you need all the headers - I was assuming a lot of the stuff under device 
was private? If you install kcanvas from kdenonbeta it puts the headers under 
include/kcanvas.

Did you remove the .cpp files from smoke/kde before typing make?
It won't regenerate the C++ code until you remove them.
