In this article we will see how we can set the stretch factor to the text of the spin box, stretching of text means expanding of text without changing their height only increasing their width. We can change the stretch factor with the help of setStretch method. The minimum stretch factor is 1, and the maximum stretch factor is 4000
In order to do this we use stretch method with the QFont object of the spin box.
Syntax : font.stretch()
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") # getting font of the spin box font = self.spin.font() # setting stretch factor font.setStretch(200) # 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) # getting stretch factor s_factor = font.stretch() # setting text to the label label.setText("Stretch Factor : " + str(s_factor)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
