In this article we will see how we can match the font of the spin box with the system font, Matching of font means it is similar to that of the system font. We can get the QFont object of spin box with the help of font
method.
Note : Make text italic or bold doesn’t mean the font has changed, by default system has Arial font. If we set different font from Arial then it will return False output as they don’t match.
In order to do this we use exactMatch method with the QFont object of the spin box
Syntax : font.exactMatch()
Argument : It takes no argument
Return : It returns bool
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 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 = QFont( 'Arial' )
# making font bold
font.setBold( True )
# setting this font to the spin box
self .spin.setFont(font)
# checking if font matches with the system font
match = font.exactMatch()
# creating a label
label = QLabel( self )
# setting geometry to the label
label.setGeometry( 100 , 200 , 300 , 50 )
# setting text to the label
label.setText( "Matches System Font : " + str (match))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
