pyqt combobox

A combobox can be created with the QComboBox class. Items are added using the class method addItem, followed by a string parameter.

Sometimes its called a listbox, as it shows a list of items a user can select from. If you want a user to choose from a set of items, the listbox is the best option.

Combobox example

The code below creates a combobox using the class QComboBox.

import sys
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QLabel, QGridLayout, QWidget, QComboBox
from PyQt5.QtCore import QSize, QRect    

class ExampleWindow(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)

        self.setMinimumSize(QSize(640, 140))    
        self.setWindowTitle("Combobox example") 

        centralWidget = QWidget(self)          
        self.setCentralWidget(centralWidget)   

        # Create combobox and add items.
        self.comboBox = QComboBox(centralWidget)
        self.comboBox.setGeometry(QRect(40, 40, 491, 31))
        self.comboBox.setObjectName(("comboBox"))
        self.comboBox.addItem("PyQt")
        self.comboBox.addItem("Qt")
        self.comboBox.addItem("Python")
        self.comboBox.addItem("Example")

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    mainWin = ExampleWindow()
    mainWin.show()
    sys.exit( app.exec_() )
