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()) |
Output :
