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
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 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()) |
Output :
