In this article we will see how we can check if the text of the spin box is fixed pitch or not, a mono-spaced font, also called a fixed-pitch, fixed-width, or non-proportional font, is a font whose letters and characters each occupy the same amount of horizontal space. This contrasts with variable-width fonts, where the letters and spacings have different widths. In order to get the information about the font we have to get the QFontInfo object of spin box which can be done using fontInfo method.
In order to do this we use fixedPitch method with the QFontInfo object of the spin box Syntax : font_info.fixedPitch() Argument : It takes no argument Return : It returns bool
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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) # setting geometry to the label label.setGeometry(100, 200, 300, 60) # getting the font info font_info = self.spin.fontInfo() # getting fixed pitch status of text check = font_info.fixedPitch() # setting text to the label label.setText("Fixed Pitch ? : " + str(check))# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
