// eclogic_lnx is the subclass 
void eclogic_lnx::on_buttonBox_clicked(QAbstractButton* button)
{
    if(button)
 
   eclogic->createTreewidget(); //eclogic is the super class and createTreewidget is the super class method name
}

// eclogic_lnx is the subclass 
void eclogic_lnx::on_buttonBox_clicked(QAbstractButton* button)
{
    if(button)

   eclogic->createTreewidget(); //eclogic is the super class and createTreewidget is the super class method name
}
