In this article we will see how we can add border to the down arrow, we know there exist two buttons up and down in spin box and down arrow is the internal part of the down button. Down arrow is the subset of down button and down button is sub set of spin box. By default there is no border to the down arrow, below is the representation of how border to the down arrow looks like.
In order to do this we have to change the stylesheet code associated with the spin box, below is the stylesheet code
QSpinBox::down-arrow { border : 4px solid green; }
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 , 60 )
# setting prefix to spin
self .spin.setPrefix( "Prefix " )
# setting suffix to spin
self .spin.setSuffix( " Suffix" )
# setting style sheet to the spin box
# adding border to the down button
# adding border to the down arrow
self .spin.setStyleSheet( "QSpinBox::down-button"
"{"
"border : 3px solid pink;"
"}"
"QSpinBox::down-arrow"
"{"
"border : 4px solid green;"
"}" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
