QSlider in vertical orientation moves in the wrong direction with macos style

XMLWordPrintable

    • macOS

      `QSlider` in vertical orientation travels in the wrong direction when dragged with a mouse. I.e. moves up when dragging down. It also does not always paint the slider notch or it paints it only partially.

      This is limited to macos style. Switching to fusion or windows style on macos fixes this.

      Qt 5.9.* seems unaffected.

       

      #include <QSlider>
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QSlider slider(Qt::Vertical);
    slider.show();
    return a.exec();
}

       

      Tested on macOS 10.11.6
