The problem with the transfer of value

[flytracer]

How multiply two SpinBox, and print result in QLabel?
If you can give some example?

[ChrisW67]

QSpinBox::value(), QLabel::setText() and some very, very basic C++. What have you tried?

Surely there is more to this question.

I have this situation

void autogentest::createValAG()
{
ValAGGroup = new QGroupBox(tr("Parameters Autogenerator"));
ValAGGroup->setFixedSize(200,500);

QLabel *Labell = new QLabel(tr("Enter a value l"));
QSpinBox *SpinBoxl = new QSpinBox; //The values of two SpinBox multiply
SpinBoxl->setRange(-100, 100);
SpinBoxl->setSingleStep(1);

QLabel *LabelR = new QLabel(tr("Enter a value R"));
QSpinBox *SpinBoxR = new QSpinBox;
SpinBoxR->setRange(-100, 100);
SpinBoxR->setSingleStep(1);
SpinBoxR->setValue(0);

}

void autogentest::createEdit()
{
EditGroup = new QGroupBox(tr("Resolt"));
EditGroup->setFixedSize(500,500);

LabelH = new QLabel; //And the result is print here
}
