    I have the license Qt for Device Creation and its maintenance.

    While trying to install, I browsed to https://doc.qt.io/QtForMCUs-2.2/.
    There are no desktop classes such as QWidget in the C++ Classes provided by Qt for MCUs 2.2.
    Is it possible to use desktop classes such as QWidget in Qt for MCUs?

    Our environment:
    Host PC Windows 10 64bit
    Client Device RaspberryPi4 modelb+ Debian 32bit

      No, Qt for MCUs uses Qt Quick Ultralite only: https://doc.qt.io/QtForMCUs-2.3/qtul-overview.html Widgets are not supported.
