PyQt5 – How to get number of maximum visible items in ComboBox

In this article we will see how we can get the number of maximum visible items of the combo box. By default at max 10 items are visible at a time in combo box drop down list although we can change this number. setMaxVisibleItems method is used to set the limit of maximum visible items. In order to get the maximum visible items number we use maxVisibleItems method

Syntax : combo_box.maxVisibleItems() Argument : It takes no argument Return : It returns integer

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, 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 max number visible limit
        self.combo_box.setMaxVisibleItems(2)

        # getting maximum visible limit
        limit = self.combo_box.maxVisibleItems()

        # creating label to show the count
        label = QLabel("Max visible limit = " + str(limit), self)

        # setting label geometry
        label.setGeometry(200, 200, 200, 30)


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
