Hi,

Go to the documentation page linked by andreyc, it shows what class to use and how to use it to limit you number input from -30 to + 30. However you can also use a "QSpinBox":http://doc.qt.io/qt-5/qspinbox.html

Do you mean QLineEdit ? Then yes and use the QIntValidator like andreyc suggested. Or you can also hide the two arrows from the QSpinBox
