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
