In this article we will see how we can get the ascent of the spin box’s font i.e text. The ascent of a font is the distance from the baseline to the highest position characters extend to. In practice, some font designers break this rule, e.g. when they put more than one accent on top of a character, or to accommodate an unusual character in an exotic language, so it is possible (though rare) that this value will be too small.
In order to do this we use ascent method with the spin box’s QFontMetrics object.
Syntax : font_metrics.ascents()
Argument : It takes no 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(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()           # getting ascent         ascent = f_metrics.ascent()           # setting text to the label         label.setText("Ascent : " + str(ascent))     # create pyqt5 app App = QApplication(sys.argv)   # create the instance of our Window window = Window()   # start the app sys.exit(App.exec())  | 
Output :
