In this article we will see how we can access the line edit object of the spin box, line edit is widget in PyQt5 which is used to display text and accept the input text. By default spin box has its own line edit object although we can add our own line edit object to it with the help of setLineEdit
method.
In order to do this we use lineEdit method
Syntax : spin_box.lineEdit()
Argument : It takes no argument
Return: It returns line edit object
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 , 600 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for widgets
def UiComponents( self ):
# creating spin box
self .spin = QSpinBox( self )
# setting geometry to spin box
self .spin.setGeometry( 100 , 100 , 250 , 40 )
# setting prefix to spin
self .spin.setPrefix( "Prefix " )
# setting suffix to spin
self .spin.setSuffix( " Suffix" )
# get the line edit object of spin box
line = self .spin.lineEdit()
# creating a label
label = QLabel( self )
# setting text to the label
label.setText( str (line))
# adjust the size of the label
label.adjustSize()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
