How to center an item editor created by a custom item delegate?

[bar0n]

i tried to change updateEditorGeometry().

void MyDelegate::updateEditorGeometry( QWidget * editor, const QStyleOptionViewItem option, const QModelIndex & index ) const
{
  QRect rect = option.rect;
 
  if (index.column() == m_VisibilityColumnIndex) 
  {
    rect.setX(rect.x() + 10);
  }
 
  editor->setGeometry(rect);
}

void MyDelegate::updateEditorGeometry( QWidget * editor, const QStyleOptionViewItem option, const QModelIndex & index ) const
{
  QRect rect = option.rect;
  
  if (index.column() == m_VisibilityColumnIndex) 
  {
    rect.setX(rect.x() + 10);
  }

  editor->setGeometry(rect);
}

To copy to clipboard, switch view to plain text mode 

but obviously the method never gets called (i set a breakpoint there). so what can i do?
