In this article we will see how we can set background color to the down button of the spin box when it get pressed. Spin box is basically have three components one is the line edit other two are up and down button, down button is used to decrement the value. This background color will only appear when down button is 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::down-button:pressed
{
background-color : red;
}
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 prefix to spin self.spin.setPrefix("Prefix ") # setting suffix to spin self.spin.setSuffix(" Suffix") # setting style sheet of spin box # adding background color to the down-button when it get pressed self.spin.setStyleSheet("QSpinBox::down-button:pressed" "{" "background-color : red;" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
