PyQt5 QSpinBox – Getting letter spacing type
In this article we will see how we can get the letter spacing type of the text of spin box, letter spacing is the distance(gap) in-between two consecutive letter. Spacing can be change by specifying the pixels or the percentage. In order to set the spacing we use setLetterSpacing
method with the QFont object of the spin box.
Letter spacing is of two types first is the PercentageSpacing which is default and its value is 0, it set the value by accepting the value in percentage for 0 pixel percentage value is 100. And the other type is AbsoluteSpacing its value is 1, it sets value by accepting the value in pixels.
In order to do this we use letterSpacingType
method with the QFont object of the spin box
Syntax : font.letterSpacingType()
Argument : It takes no argument
Return : It returns type of spacing, when it get printed it shows only the type value
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" ) # getting font of the spin box font = self .spin.font() # setting letter spacing font.setLetterSpacing(QFont.AbsoluteSpacing, 8 ) # 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 letter spacing type space_type = font.letterSpacingType() # setting text to the label label.setText( "Spacing type : " + str (space_type)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
