QComboBox drop-down list - set selected item style

Question

Is it possible to set selected item style (Qt style sheet) of the QComboBox drop-down list?

Answer 1

@Sergey Vlasov: I don't know if there is a better solution to your problem but , but I managed to solve it with the following:

class MyDelegate : public QStyledItemDelegate
{
protected:
    void paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const override
    {
        if (option.state & QStyle::State_HasFocus){
            QStyleOptionViewItem my_option = option;
            my_option.state = my_option.state ^ QStyle::State_HasFocus;
            QStyledItemDelegate::paint(painter, my_option, index);
            return;
        }
        QStyledItemDelegate::paint(painter, option, index);
    }
};

And then using your delegate in your combobox:

QStyledItemDelegate* itemDelegate = new MyDelegate();
    combobox->setItemDelegate(itemDelegate);

this eliminates nasty frame around selected item
