PyQt5 QSpinBox – Getting the under line position
In this article we will see how we can get under line position of the spin box’s text. Under line position is the distance from the base line to where an under line should be drawn. An underline, also called an underscore, is a more or less horizontal line immediately below a portion of writing. Single and occasionally double underlining is used in hand-written or typewritten documents as a way to emphasize key text.
In order to do this we use strikeOutPos
method with the spin box’s QFontMetrics object.
Syntax : font_metrics.underlinePos()
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" ) # setting under line to the font font = self .spin.font() font.setUnderline( True ) self .spin.setFont(font) # 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 the under line position value = f_metrics.underlinePos() # setting text to the label label.setText( "Under line position : " + str (value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
