In this article we will see how we can set background color to the spin box when mouse hover over it, by default the spin box is of white color although the button are of grey color but we can change the color. This background color will appear only when cursor is on the spin box.
In order to do this we have to change the style sheet associated with the spin box, below is the style sheet code
QSpinBox::hover
{
border : 1px solid green;
background-color : lightgreen;
}
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 when mouse hover over it self.spin.setStyleSheet("QSpinBox::hover" "{" "border : 1px solid green;" "background-color : lightgreen;" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
