QSpinBox* spinBox = new QSpinBox(); spinBox->setMinimum(0);
QSpinBox* spinBox = new QSpinBox(); spinBox->setMinimum(-100);
QSpinBox* spinBox1 = new QSpinBox(); QSpinBox* spinBox2 = new QSpinBox(); spinBox2->setMinimum(spinBox1->value() + 10);These examples demonstrate how to use the setMinimum function to set the minimum value of a QSpinBox. The Qt library is used to create and manipulate the QSpinBox widgets.
