In this article we will see how we can get the foreground role of the spin box, there are basically two types of roles in spin box one is foreground and the other one is background. The foreground role defines the color from the widget’s palette that is used to draw the foreground. If no explicit foreground role is set to the spin box, then foreground will be a role that contrasts with the background role.

In order to do this we use foregroundRole method with the spin box object.

Syntax : font_metrics.foregroundRole()

Argument : It takes no argument

Return : It returns ColorRole object

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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
        # 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 under line to the font
        font = self.spin.font()
        # creating a label
        label = QLabel(self)
        # making label multi line
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)
        # getting the foreground role object
        foreground = self.spin.foregroundRole()
        # setting text to the label
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
