In this article we will see how we can disconnect the spin box, disconnecting spin box means that the action which are connected to the spin box will not take place they will get disconnected. Disconnecting is exactly the opposite of connecting an action to the spin box.
In order to do this we use disconnect method
Syntax : spin_box.disconnect()
Argument : It takes no argument
Return : It returns float
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(0, 999999) # setting prefix to spin self.spin.setPrefix("Prefix ") # setting suffix to spin self.spin.setSuffix(" Suffix") # adding action to the spin box self.spin.valueChanged.connect(self.do_something) # disconnecting the spin box self.spin.disconnect() # creating label self.label = QLabel(self) # setting geometry to the label self.label.setGeometry(100, 200, 200, 70) # making it multi line label self.label.setWordWrap(True) # action called by spin box def do_something(self): # setting text to the label self.label.setText("Done Something") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() window.spin.setFocus() # start the app sys.exit(App.exec()) |
Output :
