# PyQt5 QDoubleSpinBox – Stepping By

• Last Updated : 04 Aug, 2021

In this article we will see how we can step by definite number the value of the QDoubleSpinBox programmatically. Double spin box can take decimal value as input, we can set value with the help of setValue method, stepping by will add the definite number to the current value it can be positive as well as negative.

Note : If adaptive type is selected it will add the value in decimal part else in the real part.

In order to do this we will use stepBy method with the double spin box object.
Syntax : dd_spin.stepBy(n)
Argument : It takes integer as argument
Return : It returns None

Below is the implementation

## Python3

 `# importing libraries``from` `PyQt5.QtWidgets ``import` `*``from` `PyQt5 ``import` `QtCore, QtGui``from` `PyQt5.QtGui ``import` `*``from` `PyQt5.QtCore ``import` `*``import` `sys`  `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``)`  `        ``# step type``        ``step_type ``=` `QAbstractSpinBox.AdaptiveDecimalStepType` `        ``# adaptive step type``        ``d_spin.setStepType(step_type)` `        ``# 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``)` `        ``# push button``        ``push ``=` `QPushButton(``"Press"``, ``self``)` `        ``# setting geometry to the push button``        ``push.setGeometry(``100``, ``150``, ``100``, ``35``)` `        ``# adding action to the push button``        ``# stepping by the value by 5``        ``push.clicked.connect(``lambda``: d_spin.stepBy(``5``))`    `# create pyqt5 app``App ``=` `QApplication(sys.argv)` `# create the instance of our Window``window ``=` `Window()` `# start the app``sys.exit(App.``exec``())`
