In this article we will see how we can get right bearing value of the given character from spin box’s text. The right bearing is the left-ward distance of the right-most pixel of the character from the logical origin of a subsequent character. This value is negative if the pixels of the character extend to the right of the width of the character.
In order to do this we use rightBearing
method with the spin box’s QFontMetrics object.
Syntax : font_metrics.rightBearing(ch)
Argument : It takes string as argument
Return : It returns integer.
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( 1 , 999999 )
# setting prefix to spin
self .spin.setPrefix( "PREFIX " )
# setting suffix to spin
self .spin.setSuffix( " SUFFIX" )
# setting over line to the font
font = self .spin.font()
font.setOverline( True )
self .spin.setFont(font)
# 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()
# getting right bearing value of the character
value = f_metrics.rightBearing( 'P' )
# setting text to the label
label.setText( "Right bearing value of 'P' : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
