In this article we will see how we can check if the given character in the font of the spin box is in UTF-32 format. UTF-32 is a fixed-length encoding used to encode Unicode code points that uses exactly 32 bits per code point. UTF-32 is a fixed-length encoding, in contrast to all other Unicode transformation formats, which are variable-length encodings.
In order to do this we use inFontUcs4
method with the spin box’s QFontMetrics object.
Syntax : font_metrics.inFontUcs4(unit_character)
Argument : It takes integer as 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" )
# creating a label
label = QLabel( self )
# making label multi line
label.setWordWrap( True )
# setting geometry to the label
label.setGeometry( 100 , 200 , 300 , 60 )
# getting font metrics
f_metrics = self .spin.fontMetrics()
# checking if the character is in the font
check = f_metrics.inFontUcs4( 1 )
# setting text to the label
label.setText( " UTF Format : " + str (check))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
