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 ())
