In this article we will see how we can add prefix to the spin box, prefix is basically the text which is inserted before the value of spin box, prefix remain constant for each value of spin box i.e it is not editable. In order to add prefix we will use spin_box.setPrefix method.
Syntax : spin_box.setPrefix(text) Argument : It takes string as argument Return : None
Below is the implementation
Python3
# 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 , 150 , 40 )
# adding prefix in combo box
self .spin.setPrefix("Value of x : ")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
