In this article we will see how we can set value to the QDoubleSpinBox. User can set any decimal value(float) to the QDoubleSpinBox with the help of mouse and keyboard, but sometimes there is a need of setting value programmatically in order to overwrite the value entered by the user.
In order to do this we will use setValue method with the QDateTimeEdit object.
Syntax : d_spin.setValue(val)
Argument : It takes float value as 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) # value value = 9.99 # setting current value of the double spin box d_spin.setValue(value) # creating a label label = QLabel("Lazyroar", 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 :
