The indicator branch is painted by the current style. One way of making 
sure it's not shown is by overriding the style's drawPrimitive() method 
and returning without painting anything when the selected element is 
PE_IndicatorBranch:

    @Override
    public void drawPrimitive(PrimitiveElement element, QStyleOption 
option, QPainter painter, QWidget widget) {
        if (element != PrimitiveElement.PE_IndicatorBranch)
            super.drawPrimitive(element, option, painter, widget);   
    }

A simpler solution might be to override the painting of the branch in 
the stylesheet and have it do nothing, with something like this:

    QTreeView myTreeView = new QTreeView();
    myTreeView.setStyleSheet("::branch { background: transparent;  }");

You will need to extend QTreeView and implement this behavior yourself.
