It does appear that a Q_PROPERTY of a Q_FLAG whose getter and setter operate 
on integers still compiles, but it does not for a Q_ENUM. That was broken some 
time in early 4.x, probably before 4.0, in that series of rewrites the commit 
that Aavit linked to belongs to.

Is this supported? I didn't know about it until yesterday. I doubt anyone is 
using it, though it's possible some code carried over from Qt 3 was left 
unmodified like that.

It might be possible to keep source compatibility with this, with some effort. 
Do we want to?
