The Robot Arm example demonstrates adding a C++ backend to a 3D project
created in Qt Design Studio. The example consists of an interactive
industrial robot arm in a Qt Quick 3D scene. Qt Quick Controls implements
the 2D UI to control the robot arm.
\include examples-run.qdocinc
For Qt Design Studio, the Robot Arm example comes with a QML module in
\c {backend_moc/Backend/Backend_moc.qml} that serves as a backend for the
project. The C++ application implements a compatible backend QML module.
Both QML modules implement the same API, which ensures compatibility between
the two modules.
\c {content/RoboticArm.ui.qml} defines the Qt Quick 3D scene.
\c {content/MainScreen.ui.qml} implements the 2D UI and supports a light and
dark theme. The example uses the Material style from Qt Quick Controls and
the dark and light theme to implement both modes.
