In this article we will see how we can get the point size of the text in spin box. Changing the point size will change the size of the text, pixel and point are two different things some point can have multiple pixels inside it. It is recommended to change point size for changing the size of the text, it can be changed using setPointSize method. In order to do this we use pointSize method with the QFont object of the spin box
Syntax : font.pointSize() Argument : It takes no argument Return : It returns Integer
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()
# setting point size
font.setPointSize( 20 )
# reassigning this font to the spin box
self .spin.setFont(font)
# creating a label
label = QLabel( self )
# setting geometry to the label
label.setGeometry( 100 , 200 , 300 , 60 )
# getting point size
p_size = font.pointSize()
# setting text to the label
label.setText("Point Size : " + str (p_size))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
