In this article we will see how we can access help text to the combo box. Help text is basically used to tell the programmer about the emergency information like reference links etc, programmer set help text to the combo box so that when some other programmer get difficulty in understanding the combo box, he/she can take help from the help text. In order to set the help text to the combo box we use setWhatsThis method and to access the help text we use whatsThis method.
Syntax : combo_box.whatsThis() Argument : It takes no argument Return : It returns string
Below is the implementation
# importing libraries from PyQt5.QtWidgets 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 a combo box widget
self .combo_box = QComboBox( self )
# setting geometry of combo box
self .combo_box.setGeometry( 200 , 150 , 150 , 30 )
# geek list
geek_list = ["Sayian", " Super Sayian"]
# making it editable
self .combo_box.setEditable( True )
# adding list of items to combo box
self .combo_box.addItems(geek_list)
# help text
help = "Sayian Help text"
# setting help text to the combo box
self .combo_box.setWhatsThis( help )
# getting the help text
get_help = self .combo_box.whatsThis()
# creating label to show the help text
label = QLabel(" Help text :" + get_help, self )
# setting geometry of the label
label.setGeometry( 200 , 100 , 200 , 30 )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
