PyQt5 QCommandLinkButton – Getting Help Text
In this article we will see how we can get the help text of the QCommandLinkButton. Help text is the text used to tell the other user about the usage information about the command link button. It contains the information which can be used to check the usage, limitation etc. Help text can be added to the command link button with the help of setWhatsThis method. In order to do this we use whatsThis method with the command link button object
Syntax : button.whatsThis() Argument : It takes no argument Return : It return string
Below is the implementation
Python3
# 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 , 500 , 400 ) # calling method self .UiComponents() # showing all the widgets self .show() # method for components def UiComponents( self ): # creating a command link button cl_button = QCommandLinkButton("Press", self ) # setting geometry cl_button.setGeometry( 250 , 100 , 200 , 50 ) # setting help text cl_button.setWhatsThis("Command Link Button for w3wiki") # creating label label = QLabel("w3wiki", self ) # setting label geometry label.setGeometry( 50 , 100 , 200 , 80 ) # making label multiline label.setWordWrap( True ) # getting help text value = cl_button.whatsThis() # setting text to the label label.setText(" Help Text : " + str (value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
