In this article we will see how we can step down 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 down will only decrement the value by 1 for default or by decimal if adaptive decimal type is selected.
In order to do this we will use
stepDownmethod with the double spin box object.Syntax : dd_spin.stepDown()
Argument : It takes no argument
Return : It returns None
Below is the implementation
# 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("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 down the value push.clicked.connect(lambda: d_spin.stepDown()) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
