The problem with auto-generated setters is that sometimes you'll want to 
modify them to do additional stuff.

If you're using QtCreator then Q_PROPERTY will be auto-completed and you 
just need to write the property name.

Then, right click -> refactor -> "Generate missing Q_PROPERTY members". 
(which generates the member bodies in the header file unfortunately, 

Maybe we need a "Qt language server", so all other editors would benefit 
from such refactorings.
