In this article we will see how we can get the pixel size of the text in spin box. Pixel size change the size of each pixel of the text there more the value of pixel the more text will get enlarged. We can change the pixel size with the help of setPixelSize method. In order to do this we use pixelSize method with the QFont object of the spin box
Syntax : font.pixelSize() Argument : It takes no argument Return : It returns integer
Below is the implementation
Python3
# 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 pixel size font.setPixelSize( 7 ) # 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 pixel size p_size = font.pixelSize() # setting text to the label label.setText("Pixel Size : " + str (p_size)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
Output :
