In this article we will see how we can get the height of the spin box’s font i.e its text. Height is the vertical length of the text. Height of font is always equal to ascent +descent +1 (the 1 is for the base line).
In order to do this we use height
method with the spin box’s QFontMetrics object.
Syntax : font_metrics.height()
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" )
# creating a label
label = QLabel( self )
# making label multi line
label.setWordWrap( True )
# setting geometry to the label
label.setGeometry( 100 , 200 , 300 , 60 )
# getting font metrics
f_metrics = self .spin.fontMetrics()
# getting height of the font
height = f_metrics.height()
# setting text to the label
label.setText( "Height : " + str (height))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
