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()) |
Output :
