In this article we will see how we can get the content of item at specific index in the combo box. In order to do this we will use the itemText method.
Syntax : combo_box.itemText(index)
Argument : It takes integer as argument
Return : It return string i.e content of item
Steps for implementation –
1. Create a combo box
2. Add items to combo box
3. Create push button
4. Add action to the push button
5. Create label to show content
6. Inside the action get the content of specific index in combo box with the help of itemIndex method and store it in variable
7. Show the content in label with the help of setText method.
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) # creating push button button = QPushButton("Show content ", self) print(self.combo_box.count()) # adding action to button button.pressed.connect(self.find) # creating label self.label = QLabel(self) # setting geometry of the label self.label.setGeometry(200, 200, 200, 30) def find(self): # index index = 2 # finding the content at index in combo box content = self.combo_box.itemText(index) # showing content on the screen through label self.label.setText("Content at index 2: " + content)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
