Below is the implementation of this method.
# importing the required libraries from PyQt5.QtGui import * from PyQt5.QtWidgets import * import sys
class Window(QMainWindow):
def __init__( self ):
super ().__init__()
# set the title
self .setWindowTitle( "Tooltip" )
# set the geometry
self .setGeometry( 0 , 0 , 300 , 300 )
# creating a button widget
self .widget = QPushButton( 'Widget' , self )
# setting up the tooltip
self .widget.setToolTip( "This is a button widget !" )
# show all the widgets
self .show()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
