QStyledItemDelegate paint QPushButton with stylesheet

[Talei]

Hello,
I struggle with painting QPushButton with inherited styleSheet in custom delegate.
Delegate parent is TreeView with styleSheet.

The way I paint it in my QStyledItemDelegate.

void Delegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    QStyleOptionButton pb_Style;
       pb_Style.state |= QStyle::State_Raised | QStyle::State_Enabled | option.state;
 
       QRect pbRect = option.rect;
             ...
 
       pb_Style.rect = pbRect;
       pb_Style.text = QString();
 
       style->drawControl(QStyle::CE_PushButton, &pb_Style, painter, qobject_cast<QWidget *>(this->parent()) );
}

void Delegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    QStyleOptionButton pb_Style;
       pb_Style.state |= QStyle::State_Raised | QStyle::State_Enabled | option.state;

       QRect pbRect = option.rect;
             ...
       
       pb_Style.rect = pbRect;
       pb_Style.text = QString();

       style->drawControl(QStyle::CE_PushButton, &pb_Style, painter, qobject_cast<QWidget *>(this->parent()) );
}

To copy to clipboard, switch view to plain text mode 

In short I don't know how to paint QPushButton with inherited styleSheet from the view.
Any suggestions are more then welcome.
