Have to say, QT works pretty much flawlessly, adding c++ classes is a dream, and yes signals and slots work exactly as expected.

I managed to port my IOS apps almost entirely into QML/Javascript with a few core functions handed off to c++ as required.

Screen layout and design works like a charm even through rotations setting things like font sizes to a percentage of the current layout object for instance it renders excellently on all the different screen sizes and resolutions I have thrown it at.

Good choice, thanks
