pyqt menu

If you’re diving into GUI development in Python, understanding how to implement a menu in PyQt4 is essential. This guide will walk you through creating a PyQt menu using the Qt framework, providing hands-on insights.

PyQt4 is renowned for its capacity to create rich and interactive GUI applications. One of its salient features is the menus which typically appear at the top of the application window. These menus offer users easy navigation and control over the application’s functionalities.

The QMainWindow class forms the foundation of your application window. The nifty menuBar() method, a part of this class, helps in adding the desired title bar to the window.

But how do you add individual menus to this title bar? That’s where addMenu() steps in. And to enrich these menus with commands, you can employ the addAction method.

Creating a PyQt4 Menu Bar

Curious about how you can add a menu bar to your PyQt4 application? The following code snippet illustrates this procedure with clarity:

#! /usr/bin/env python
# -*- coding: utf-8 -*-
import sys
from PyQt4.QtGui import *

# Initiate an PyQT4 application object.
a = QApplication(sys.argv)

# The QWidget widget is the base for all user interface objects in PyQt4.
w = QMainWindow()

# Define window parameters
w.resize(320, 240)
w.setWindowTitle("Hello World!")

# Establish main menu
mainMenu = w.menuBar()
mainMenu.setNativeMenuBar(False)
fileMenu = mainMenu.addMenu('&File')

# Integrate exit button
exitButton = QAction(QIcon('exit24.png'), 'Exit', w)
exitButton.setShortcut('Ctrl+Q')
exitButton.setStatusTip('Exit application')
exitButton.triggered.connect(w.close)
fileMenu.addAction(exitButton)

# Display window
w.show()

sys.exit(a.exec_())
