Qt5 Alternative to QWS Multi Display setup



  • Hi everybody!

    I want to switch from Qt 4.8 to Qt 5.1 but I figured out that QWS died in Qt 5.

    Formerly I used
    @[QTPROGRAMMNAME] -qws -display "multi: LinuxFB:/dev/fb0:0 LinuxFb:/dev/fb2:offset=1024,0:1 :0"@

    to set up two displays so that I could arrange multiple qt applications on these screens by using the QWS functions.
    What is now the equivalent for Qt5 and later?

    Every hint is highly appreciated!

    Best regards
    Florian



  • Hi Florian,

    There is no real equivalent at the moment when it comes to using multiple displays at the same time.

    You can run the app with -platform linuxfb:fb=/deb/fbN to use a specific framebuffer device but you cannot specify multiple ones. For that, I have created https://bugreports.qt-project.org/browse/QTBUG-36114

    Cheers,
    Laszlo
