n PyQt5 there are lots of widgets and bars and when we tend to make an application, we end up putting lots of windows and for each window there exit status bar. Sometimes we can’t remember why this status bar is used and what is this status bar. That’s why for back-end purposes PyQt5 allows us to set help text. In this article we will see how to set and access help text for status bar.
In order to set help text we use setWhatsThis()
method and for accessing the help text we use whatsThis()
method.
Syntax :
self.statusBar().setWhatsThis() self.statusBar().whatsThis()Argument :
setWhatsThis()
takes string as argument.whatsThis()
takes no argument.Return :
setWhatsThis()
return NonewhatsThis()
returns string.
Code:
from PyQt5.QtCore import * from PyQt5.QtGui import * from PyQt5.QtWidgets import * import sys
class Window(QMainWindow):
def __init__( self ):
super ().__init__()
# set the title
self .setWindowTitle( "Python" )
# setting the geometry of window
self .setGeometry( 60 , 60 , 600 , 400 )
# setting status bar message
self .statusBar().showMessage( "This is status bar" )
# setting border
self .statusBar().setStyleSheet( "border :3px solid black;" )
# setting help text
self .statusBar().setWhatsThis( "this is help text for status bar" )
# creating a label widget
self .label_1 = QLabel( self )
# moving position
self .label_1.move( 100 , 100 )
# setting up the border
self .label_1.setStyleSheet( "border :1px solid blue;" )
# accessing help text of status bar
help = self .statusBar().whatsThis()
# setting text to label
self .label_1.setText( help )
# resizing label
self .label_1.adjustSize()
# 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 ())
