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 librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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("neveropen", 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
