    Default Qt/Embedded: QWS Frame buffer resolution change at run time ...

    Hi All,

    We know that when Qt application executed with qws, it will find the frame buffer resolution and display for that.
    But how can we conciliate this when frame buffer resolution change at run time?
    Welcome to discuss this ...

    My project works on Qt/Embedded but on x86_64, to switch frame buffer resolution I use fbset utility. With Matrox G550e video card I also use matroxset tool.
