PyQt5 QSpinBox – Checking if there is over line or not
In this article we will see how we can check if there over line to the text of spin box. An over line, overscore, or over bar, is a typographical feature of a horizontal line drawn immediately above the text. By default there is no over line to the text although we can set the over line with the help of setOverline method.
In order to do this we use overline method with the QFont object of the spin box
Syntax : font.overline()
Argument : It takes no argument
Return : It returns bool
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") # getting font of the spin box font = self.spin.font() # setting over-line font.setOverline(True) # reassigning this font to the spin box self.spin.setFont(font) # creating a label label = QLabel(self) # setting geometry to the label label.setGeometry(100, 200, 300, 60) # checking if there is over line or not check = font.overline() # setting text to the label label.setText("Over Line ?: " + str(check)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
