In this article we will see how we can add border to the up arrow when it is in anti pressed state, we know there exist two buttons up and down in spin box and up arrow is the internal part of the up button. Up arrow is the subset of up button and up button is subset of spin box. By default there is no border to the up arrow although we can add it, customized border will only appear when it didn’t get pressed. In order to do this we have to change the style sheet code associated with the spin box, below is the stylesheet code
QSpinBox::up-arrow:!pressed { border : 4px solid red; }
Below is the implementation
Python3
# 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 )
# seting 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 up arrow
# and when it is in anti pressed state
self .spin.setStyleSheet("QSpinBox::up - button"
"{"
"border : 3px solid lightgreen;"
"}"
"QSpinBox::up - arrow:! pressed"
"{"
"border : 4px solid red;"
"}")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
