In this article we will see how we can get the horizontal physical DPI of the spin box. DPI refers to the physical dot density of an image when it is reproduced as a real physical entity, for example printed onto paper. A digitally stored image has no inherent physical dimensions, measured in inches or centimeters.
In order to do this we use physicalDpiX method with the spin box object.
Syntax : spin_box.physicalDpiX()
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") # creating a label label = QLabel(self) # making the label multi line label.setWordWrap(True) # setting geometry to the label label.setGeometry(100, 200, 200, 60) # getting horizontal Physical DPI value = self.spin.physicalDpiX() # setting text to the label label.setText("Horizontal Physical DPI : " + 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 :
