In this article we will see how we can use the editing finished signal of the spin box, editing finished is the signal generated by the spin box when enter is pressed. We know we can ad action to the spin box when its value get changed but calling a method every time the value get changed is no required sometimes method should get called only when value is set and enter is pressed i.e editing is finished of spin box.
In order to do this we use editingFinished.connec method.
Syntax : spin_box.editingFinished.connect(method_name)
Argument : It takes method name as argument as argument
Action Performed : It calls the passed method every time editing is finished
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 prefix to spin
self .spin.setPrefix( "Prefix " )
# setting suffix to spin
self .spin.setSuffix( " Suffix" )
# creating a label
self .label = QLabel( "Label " , self )
# setting geometry to the label
self .label.setGeometry( 100 , 150 , 300 , 70 )
# adding action when editing get finished
self .spin.editingFinished.connect( self .do_action)
# method called after editing finished
def do_action( self ):
# getting current value of spin box
current = self .spin.value()
self .label.setText( "Editing finished, final value : " + str (current))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
