In this article we will see how we can check if the spin box visible with the help of isVisible method. We can hide the spin box using hide method or setHidden method. By default spin box is visible.
Note : If we use this method inside the window class it will return false as the window is created at that time and it didn’t know if it is visible or not therefore it is used outside the class
In order to do so we use isVisible method.
Syntax : classs_object.spin_box.isVisible()
Argument : It takes no argument
Return : It returns bool
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") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # checking if the spin box was visible check = window.spin.isVisible() # printing the status print(check) # start the app sys.exit(App.exec()) |
Output :
True
