In this article we will see how we can add border to the down button of spin box when mouse hover over it. Spin box consist of two buttons up and down, down button is used to decrement the value, it has its own default border although we can change it. Customized border will appear to the down button when mouse hover over it.
In order to do this we have to change the style sheet code associated with the spin box, below is the stylesheet code
QSpinBox::down-button:hover
{
border : 4px solid blue;
}
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 to the spin box # adding border to the down button of spin box # and when mouse hover over it self.spin.setStyleSheet("QSpinBox::down-button:hover" "{" "border : 4px solid red;" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
