    delete ui;
}

void EscogerPuesto::asientoClickeado()
{
    std::cout<<"click en asiento";

Answer 1

Button group contains signal with parameter QAbstractButton* or int, so you should connect this signal with slot which has an appropriate parameter.

    ui->buttonGroup->connect(ui->buttonGroup, SIGNAL(buttonClicked(QAbstractButton*)),
                             this, SLOT(your_slot(QAbstractButton* ));

Or you can connect each button with some slot.
