In this article we will see how we can access the item role in combo box. By default when we create a combo box and add items to it no role is set to the items. In order to set the role we use setItemData method and in order to access the role we use itemData method.
Syntax : combo_box.temData(index)
Argument : It takes integer as argument
Return : It will return string i.e role
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, 120, 30) # geek list geek_list = ["Geek", "Geeky Geek", "Legend Geek", "Ultra Legend Geek"] # adding list of items to combo box self.combo_box.addItems(geek_list) # setting roles to the items self.combo_box.setItemData(0, "First role") self.combo_box.setItemData(1, "Second role") self.combo_box.setItemData(2, "Third role") self.combo_box.setItemData(3, "Fourth role") # getting role role = self.combo_box.itemData(0) # creating label to print the role label = QLabel("Geek role : " + role, self) # setting geometry label.setGeometry(200, 200, 150, 30)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
