In this article we will see how we can set 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.

In order to change the maximum visible items number we use setMaxVisibleItems method.

Syntax : combo_box.setMaxVisibleItems(n)

Argument : It takes integer as argument

Action performed : It will set maximum number of visible items

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 max number visible limit
        self.combo_box.setMaxVisibleItems(2)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
