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
setDecimals
method 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( "GeeksforGeeks" , 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 ())
