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 ())
