Demonstrates how to add a C++ backend to a 3D project from Qt Design Studio. This example demonstrates adding a C++ backend to a 3D project created in Qt Design Studio. The example itself consists of an interactive industrial robot arm in a Qt Quick 3D scene. The 2D UI to control the robot arm is implement using Qt Quick Controls.
For Qt Design Studio the Robot Arm Example comes with a simple QML based QML module in backend_moc/Backend/Backend_moc.qml, that serves as a backend for the project when using it with Qt Design Studio. The C++ application implements a compatible backend as a C++ based QML module. Both QML modules implement the same API, which ensures compatibility between the two modules.
The Qt Quick 3D scene for the Robot Arm is defined in content/RoboticArm.ui.qml. The 2D UI is implemented in content/MainScreen.ui.qml and is repsonsive and also supports a light and dark mode. The example uses the Material style from Qt Quick Controls and the dark and light theme to implement both modes.
