QToolButton + style sheet problem

[John82]

Does anyone know if this is correct?

tb = new QToolButton (_viewGroup);
  tb->setText ("Trial");
  tb->setFixedWidth (150);
  tb->setFixedHeight (40);
  tb->setArrowType (Qt::DownArrow);
  tb->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);
 
  // This section here ???
  tb->setStyleSheet ("down-arrow: subcontrol-position: right center");

tb = new QToolButton (_viewGroup);
  tb->setText ("Trial");
  tb->setFixedWidth (150);
  tb->setFixedHeight (40);
  tb->setArrowType (Qt::DownArrow);
  tb->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);

  // This section here ???
  tb->setStyleSheet ("down-arrow: subcontrol-position: right center");

To copy to clipboard, switch view to plain text mode 

I want to move the arrow to the right
