In this article we will see how we can add border to the down arrow when mouse hover over it, we know there exist two buttons up and down in spin box and down arrow is the internal part of the down button. Down arrow is the subset of down button and down button is subset of spin box. By default there is no border to the down arrow. Customized border will only appear when cursor is on the spin box.
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-arrow:hover
{
border : 4px solid green;
}
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, 60) # 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 # adding border to the down arrow # when mouse hover over it self.spin.setStyleSheet("QSpinBox::down-button" "{" "border : 3px solid pink;" "}" "QSpinBox::down-arrow:hover" "{" "border : 4px solid green;" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
