Checkbox save state.

[Project25]

I have Qcheckbox and combobox in one horizontal layout. How do I save the state of QCheckbox when I change the current index of combobox? For instance if I select first time in comboBox and I checked the checkbox and then I select second item "Test2" and I unchecked the checkbox. Now I select the first item again and my checbox is unchecked (that should be checked). How would I save the state of checkbox before I move to next item in comboBox.

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
 
    QWidget *pWidget = new QWidget();
	pWidget->setFixedSize(220,150);
 
	QComboBox* pComboBox = new QComboBox(pWidget);
	pComboBox->addItems((QStringList() << "Test1"<<"Test2" << "Test3"));
	QCheckBox* pCheckBox = new QCheckBox(pWidget);
	pCheckBox->setChecked(true); 
 
    QHBoxLayout *layout = new QHBoxLayout;
    layout->addWidget(pComboBox);
	layout->addWidget(pCheckBox);
    pWidget->setLayout(layout);
    pWidget->show();
    return app.exec();
}

int main(int argc, char **argv)

    QWidget *pWidget = new QWidget();

	QComboBox* pComboBox = new QComboBox(pWidget);
	pComboBox->addItems((QStringList() << "Test1"<<"Test2" << "Test3"));
	QCheckBox* pCheckBox = new QCheckBox(pWidget);
	pCheckBox->setChecked(true); 

    QHBoxLayout *layout = new QHBoxLayout;
    layout->addWidget(pComboBox);
	layout->addWidget(pCheckBox);
    pWidget->setLayout(layout);
    pWidget->show();
    return app.exec();
}
