if you mean live preview, it’s been answered elsewhere. see this thread [qt-project.org]
But I’ve seen some QtDD QML videos, they just re-run (Ctrl+R in Qt Creator) the program. Because you don’t change your c++ backend, you don’t need to recompile so the re-run seemed instantaneous. This reason alone made me want to develop in QML.
That said, I agree that live preview feature in Qt Creator would be awesome. Sometimes in a relatively large project you have a long list of startup routine that might take some time.
