In this article we will see how we can set decimal precision of the QDoubleSpinBox. By default decimal precision of double spin box is 2 although we can change it any time. Decimal precision is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a decimal precision of 2.
In order to do this we will use
setDecimalsmethod with the double spin box object.Syntax : dd_spin.setDecimals(n)
Argument : It takes integer 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) # setting decimal precision d_spin.setDecimals(4) # step type step_type = QAbstractSpinBox.AdaptiveDecimalStepType # adaptive step type d_spin.setStepType(step_type) # 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 :
