In this article we will see how we can make the text of the spin box bold, in order to set the font use setFont method which takes QFont object as argument. In order to make the text i.e font bold we have to get the QFont object of the spin box then make it bold then reassign it to the spin box.
In order to do this we use setBold method with the QFont object of the spin box
Syntax : font.setBold(True)
Argument : It takes bool as argument
Return : It returns 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 , 250 , 40 )
# setting range to the spin box
self .spin.setRange( 0 , 999999 )
# setting prefix to spin
self .spin.setPrefix("Prefix ")
# setting suffix to spin
self .spin.setSuffix(" Suffix")
# getting font of the spin box
font = self .spin.font()
# making font bold
font.setBold( True )
# setting back this font to the spin box
self .spin.setFont(font)
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
