In this article we will see how we can get over line position of the spin box’s text. Over line position is the distance from the base line to where an over line should be drawn. An over line, overs core, or over bar, is a typographical feature of a horizontal line drawn immediately above the text. In mathematical notation, an over line has been used for a long time as a vinculum, a way of showing that certain symbols belong together.
In order to do this we use overlinePos method with the spin box’s QFontMetrics object.
Syntax : font_metrics.overlinePos()
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(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 over line position value = f_metrics.overlinePos() # setting text to the label label.setText("Distance b / w base and over line : " + 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 :
