Can Qt dynamically switch platform plugins while running?

  • From this bug-report,


    I gather it isn't possible on Qt 5.9 to redirect Qt's display, as it appears on the screen of an embedded device, and reflect it on a remote VNC-client. (As used to be possible on Qt 4.8.)

    But I wondered, is it possible, while Qt is running, to switch dynamically between platform plugins: e.g. to blank out the screen of the device and switch, temporarily to vnc, and allow a remote VNC-client to connect for a while?

    TIA -- s.

    Hi and welcome to devnet,

    To the best of my knowledge, it's currently not.
    One possible way might be to use wayland and have the VNC served through it. Just an idea, I can't guarantee it's working.

  • Thank you for responding. I shall have to try a different tack ..
