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
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
