Hello,

Thanks for your questions. I try to answer them to the extend of my 
knowledge :)

Mainly because I promised to look at (and demo) Qt & Ubuntu Phone development and I already have a ready project with (very small) C++ backend. I intend to demo the project with desktop, Android and Ubuntu Phone environments. Desktop and Android are already covered so Ubuntu Phone remains to be checked.

For the desktop target the QtC has the Kits. Running a pure QML app on 
the device needs nothing else but hitting the Ctrl+F12 as you have 
figured out. The script behind this shortcut is the
/usr/share/qtcreator/ubuntu/scripts/qtc_device_run_app provided by the 
qtcreator-plugin-ubuntu-common package. That command will execute the 
qmlscene on the device with a bunch of variable settings and parameters.

The on device build feature is limited to .deb packaging of platform 
level projects. That is hardly even needed for application development.

When your application is a QML/C++ project you need to first build in 
the click chroot. Click chroot you can create in the Options, Ubuntu tab.

The qmake (.pro) projects are not supported, so I suggest to stick to 
cmake projects. You can find a good template hen you create a new 
project. Please choose the "QML Extension Library + Tabbed UI"

If you have questions please ping me (bzoltan) or Benjamin (zbenjamin) 
on #ubuntu-app-devel IRC channel.
