In this article we will see how we can make the spin box visible with the help of show
method. We can hide the spin box using hide
method or setHidden
method. By default spin box is visible. show
method is exact opposite of hide
method
In order to do so we use show
method.
Syntax : spin_box.show()
Argument : It takes no argument
Action performed : Makes spin box visible
Implementation steps :
1. Create a spin box
2. Create a push button
3. Add action to the push button
4. Inside the push button make the spin box hidden with the help of hide method
5. Create another push button
6. Inside the action make the spin box visible with the help of show method
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 push button
button = QPushButton( "Hide" , self )
# setting button geometry
button.setGeometry( 100 , 160 , 100 , 40 )
# adding action to the push button
button.clicked.connect( self .push_method)
# creating push button
e_button = QPushButton( "Show" , self )
# setting button geometry
e_button.setGeometry( 220 , 160 , 100 , 40 )
# adding action to the push button
e_button.clicked.connect( self .another_method)
# method called by push button
def push_method( self ):
# making spin box hide
self .spin.hide()
# method called by e_button
def another_method( self ):
# making spin box visible
self .spin.show()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
