In this article we will see how we can repaint the spin box. With the help of painter events we can paint the spin box however user wants it to be, but some times there is a need to repaint the spin box to ensure the painter event action.
In order to do this we use repaint
method with the spin box object.
Syntax : spin_box.repaint()
Argument : It takes no argument
Return : It returns None
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( 1 , 999999 )
# setting prefix to spin
self .spin.setPrefix( "PREFIX " )
# setting suffix to spin
self .spin.setSuffix( " SUFFIX" )
# setting background color to the spin box
self .spin.setStyleSheet( "QSpinBox"
"{"
"background : lightgreen;"
"}" )
# repaint the spin box
self .spin.repaint()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
