PyQt5 QSpinBox – Getting height of font
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 ()) |
