qt pushed icon and widgetbox

[giugio]

hello.
I wish create a delegate that draw an icon with two state raised and pushed based on the state of the button.
I think to draw a QStyleOptionButton with the icon , but my code don't work.

void CustomItemDelegate::paint(QPainter *painter,
                   const QStyleOptionViewItem &option,
                   const QModelIndex &index) const
{
   /*const QAbstractListModel* model = 
   static_cast<const QAbstractListModel*>(index.model());
   QStandardItem* item = model->item(index.row());*/
 
 
   QString text = "pipo";
   QRect rect = option.rect;
 
    QRect textRect( rect);
    textRect.setHeight( 30);
    painter->drawText(textRect,text);
 
    QRect buttonRect( rect);
    buttonRect.setY(textRect.y()+ 35);
    buttonRect.setHeight( 30);
    QStyleOptionButton button;
	QIcon undoicon = QIcon::fromTheme("edit-undo", QIcon(":/undo.png"));
 
	button.icon = undoicon;
	button.iconSize = QSize(32,32);
 
	button.rect = buttonRect;
    button.text = text;
    button.state = _state | QStyle::State_Enabled;
 
    QApplication::style()->drawControl
        (QStyle::CE_PushButton, &button, painter);
}

void CustomItemDelegate::paint(QPainter *painter,
                   const QStyleOptionViewItem &option,
                   const QModelIndex &index) const
{
   /*const QAbstractListModel* model = 
   static_cast<const QAbstractListModel*>(index.model());
   QStandardItem* item = model->item(index.row());*/

   
   QString text = "pipo";
   QRect rect = option.rect;

    QRect textRect( rect);
    textRect.setHeight( 30);
    painter->drawText(textRect,text);

    QRect buttonRect( rect);
    buttonRect.setY(textRect.y()+ 35);
    buttonRect.setHeight( 30);
    QStyleOptionButton button;
	QIcon undoicon = QIcon::fromTheme("edit-undo", QIcon(":/undo.png"));
	
	button.icon = undoicon;
	button.iconSize = QSize(32,32);
	
	button.rect = buttonRect;
    button.text = text;
    button.state = _state | QStyle::State_Enabled;

    QApplication::style()->drawControl
        (QStyle::CE_PushButton, &button, painter);
}

To copy to clipboard, switch view to plain text mode 

my goal is to use a widget like the widgetbox desingner but with a pressed /raised icon.
