PyQt5 QDoubleSpinBox – Setting Line Edit to it

In this article we will see how we can set the line edit to the QDoubleSpinBox. Line edit is the white space which receives the input and shows the current value of the double spin box, we can change the line edit object any time. Line edit is the main component of the double spin box the default line edit is made such that it receives only float values.

In order to do this we will use setLineEdit method with the double spin box object.

Syntax : dd_spin.setLineEdit(lineedit)

Argument : It takes QLineEdit object as argument

Return : It returns None

Below is the implementation

# importing libraries

class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 500, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for components
    def UiComponents(self):

        # creating double spin box
        d_spin = QDoubleSpinBox(self)

        # setting geometry to the double spin box
        d_spin.setGeometry(100, 100, 150, 40)

        # setting decimal precision
        d_spin.setDecimals(1)

        # step type
        step_type = QAbstractSpinBox.AdaptiveDecimalStepType

        # adaptive step type
        d_spin.setStepType(step_type)

        # line edit
        lineedit = QLineEdit(self)

        # setting line edit to the double spin box
        d_spin.setLineEdit(lineedit)


        # creating a label
        label = QLabel("GeeksforGeeks", self)

        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)

        # making label multi line
        label.setWordWrap(True)





# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
