In this article we will see how we can get the MM Height of the spin box. MM Height is basically the height of the paint device in millimeters. Due to platform limitations it may not be possible to use this function to determine the actual physical size of a spin box on the screen.
In order to do this we use heightMM
method with the spin box object.
Syntax : spin_box.heightMM()
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 MM Height of spin box
value = self .spin.heightMM()
# setting text to the label
label.setText( "MM Height = " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
