In this article we will see how we can set background image to the spin box’s down arrow for its various states. Spin box has two child one is the line edit and other are the up and down button. Down arrow is the internal component of the down button down arrow is the place arrow is displayed, there are basically three states of this one is normal state, second is the hover state i.e when cursor is on the down button and third is the pressed state.
In order to do this we have to change the style sheet associated with the spin box, below is the style sheet code
QSpinBox::down-arrow { background-image : url(image1.png); } QSpinBox::down-arrow:hover { background-image : url(image2.png); } QSpinBox::down-arrow:pressed { background-image : url(image3.png); }
This will add three different background image for each state of the down arrow, there are also some additional states like anti-hover (!hover) and anti-pressed(!pressed) these are opposite of hover and pressed state respectively.
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 , 9999 )
# setting prefix to spin
self .spin.setPrefix( "PREFIX " )
# setting suffix to spin
self .spin.setSuffix( " SUFFIX" )
# setting style sheet
# adding background image to down arrow
# adding background image to down arrow
# for hover and pressed state
self .spin.setStyleSheet( "QSpinBox::down-arrow"
"{"
"background-image : url(image.png);"
"}"
"QSpinBox::down-arrow:hover"
"{"
"background-image : url(skin.png);"
"}"
"QSpinBox::down-arrow:pressed"
"{"
"background-image : url(logo.png);"
"}"
)
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
