In this article we will see how we can check if there is under line to the spin box’s text. An underline, also called an underscore, is a more or less horizontal line immediately below a portion of writing. Single and occasionally double underlining is used in hand-written or typewritten documents as a way to emphasise key text. We can add under line to the spin box’s text with the help of setUnderline method.
In order to do this we use underline method with the QFont object of the spin box.
Syntax : font.underline()
Argument : It takes no argument
Return : It returns bools
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 under line font.setUnderline(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 text has under line check = font.underline() # setting text to the label label.setText("Under 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 :
