In this article we will see how we can set value to the spin box. By default its value is 0 although user can change it any time. In order to change its value programmatically we will use setValue
method
Syntax : spin.setValue(n)
Argument : It takes integer as argument
Return : None
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 , 100 , 40 ) # setting value to the spin box self .spin.setValue( 20 ) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() window.show() # start the app sys.exit(App. exec ()) |
