In this article we will see how we can set limit to the number of items in the combo box. When we create a combo box there is no limit set to the items we can add any number of items although sometimes condition arises to set the maximum limit to the items.
In order to set the maximum limit to the number of items we use setMaxCount method.
Syntax : combo_box.setMaxCount(n)
Argument : It takes integer as argument
Action performed : This will set maximum limit to the number of items in combo box
Below is the implementation –
# 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, 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 maximum number limit of items self.combo_box.setMaxCount(2) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
