In this article we will see how we can get the pixel ratio scale for the spin box. The device pixel ratio is the ratio between physical pixels and logical pixels of the spin box. Pixel ratio scale is the type of variable measurement scale which is quantitative in nature. Ratio scale allows any researcher to compare the intervals or differences.
In order to do this we use devicePixelRatioFScale method
Syntax : spin_box.devicePixelRatioFScale()
Argument : It takes no argument
Return : It returns float
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 pixel ratio scale
pixel_ratio_scale = self .spin.devicePixelRatioFScale()
# creating label
label = QLabel( self )
# setting geometry to the label
label.setGeometry( 100 , 200 , 200 , 70 )
# making it multi line label
label.setWordWrap( True )
# setting text to the label
label.setText( "Pixel Ratio Scale : " + str (pixel_ratio_scale))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
window.spin.setFocus() # start the app sys.exit(App. exec ())
