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): 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 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() font.setUnderline(True) self.spin.setFont(font) # creating a label label = QLabel(self) # making label multi line label.setWordWrap(True) # 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 label.setText(str(type(foreground))) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
