In this article we will see how we can set background color to the spin box when it get pressed, by default the spin box is of white color although the button are of grey color but we can change the color. This background color will appear only when any of the up and down button get pressed. In order to do this we have to change the style sheet associated with the spin box, below is the style sheet code
QSpinBox::pressed { border : 1px solid blue; background-color : lightblue; }
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 )
# setting geometry to spin box
self .spin.setGeometry( 100 , 100 , 250 , 40 )
# setting prefix to spin
self .spin.setPrefix("Prefix ")
# setting suffix to spin
self .spin.setSuffix(" Suffix")
# setting style sheet of spin box
# adding background color when it get pressed
self .spin.setStyleSheet("QSpinBox::pressed"
"{"
"border : 1px solid blue;"
"background - color : lightblue;"
"}")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
