    Hi there.. again..

    I managed to change my Fusion Style color palette from light to dark and vise versa.
    But now, i stumble across another Problem with that Method.

    In some of my Windows, i need a vertical TabBar, that holds Tabs with Horizontal Text.
    To achive this, i took this snippet of code:

    #include <QProxyStyle>
    
    class WestTabH_Text : public QProxyStyle {
    public:
      QSize sizeFromContents(ContentsType type, const QStyleOption* option,
                             const QSize& size, const QWidget* widget) const {
        QSize s = QProxyStyle::sizeFromContents(type, option, size, widget);
        if (type == QStyle::CT_TabBarTab) {
          s.transpose();
        }
        return s;
      }
    
      void drawControl(ControlElement element, const QStyleOption* option, QPainter* painter, const QWidget* widget) const {
        if (element == CE_TabBarTabLabel) {
          if (const QStyleOptionTab* tab = qstyleoption_cast<const QStyleOptionTab*>(option)) {
            QStyleOptionTab opt(*tab);
            opt.shape = QTabBar::RoundedNorth;
            QProxyStyle::drawControl(element, &opt, painter, widget);
            return;
          }
        }
        QProxyStyle::drawControl(element, option, painter, widget);
      }
    };
    

    And set it as Style for the TabBar

    ui->TabView_Database->tabBar()->setStyle(new WestTabH_Text);
    

    Looks great in standard fusion light Theme... but gives me a Problem in the dark one.. see:

    I´m not familiar with the Palette and Style thing.. so it would be nice, if you People can help me out here.. How can i set the Style of the TabBar to fit the current Palette?

      Hi,

      My guess is that it still wraps the previous style.
      I would recreate the proxy style when switching between your themes.
