Thanks again, it is always a pleasure to get such qualified answers.
I had this strange misbehaviour, which I described in my first post.
To test the problem again, I started the same project from scratch.
This time the problem did not occur. So I was able to see my
QML-changes at once without recompile. So I think I had a
misconfiguration in my old project or there is a (little) bug somewhere
in the build-system.
@Rolias: Same with me. Having the qml's in the qrc is comfortable. You
don't have to care for file locations and so on.
@Torgair: If I understand correctly, you bind the shortcut into every
application which you develop, so you can edit and test your qml at
runtime. Is it correct? Perfect trick.
Thanks again
