In this article we will see how we can get the background role of the spin box, there are basically two types of roles in spin box one is foreground and the other one is background. Background role defines the brush from the spin box’s palette that is used to render the background. If no explicit background role is set, the spin box inherits its parent widget’s background role. In order to set this, we use setBackgroundRole method.
In order to do this we use backgroundRole method.
Syntax : spin_box.backgroundRole()
Argument : It takes no argument
Return : It returns QPalette.ColorRole object but when printed it shows its value
Below is the implementation
Python3
# 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" ) # creating a label label = QLabel( self ) # setting geometry to the label label.setGeometry( 100 , 200 , 300 , 30 ) # getting the background role object object = self .backgroundRole() # setting text to the label label.setText( "Background role object value : " + str ( object )) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
