In this article we will see how we can set the line edit to the QDoubleSpinBox. Line edit is the white space which receives the input and shows the current value of the double spin box, we can change the line edit object any time. Line edit is the main component of the double spin box the default line edit is made such that it receives only float values.
In order to do this we will use
setLineEdit
method with the double spin box object.Syntax : dd_spin.setLineEdit(lineedit)
Argument : It takes QLineEdit object 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( 1 )
# step type
step_type = QAbstractSpinBox.AdaptiveDecimalStepType
# adaptive step type
d_spin.setStepType(step_type)
# line edit
lineedit = QLineEdit( self )
# setting line edit to the double spin box
d_spin.setLineEdit(lineedit)
# 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 ())
