wxpython menu

Most desktop applications have a window menu. They may look different depending the operating system.

wxPython will make every desktop application look like a native app. If you want the same appearance on every platform consider using another GUI framework.

wxPython menu

The code below will create a menubar in your wxPython window:

#!/usr/bin/python
 
import wx
 
app = wx.App()
 
frame = wx.Frame(None, -1, 'win.py')
frame.SetDimensions(0,0,200,50)
 
# Setting up the menu.
filemenu= wx.Menu()
filemenu.Append(101, "Open", "Open")
filemenu.Append(102, "Save", "Save")
filemenu.Append(wx.ID_ABOUT, "About","About")
filemenu.Append(wx.ID_EXIT,"Exit","Close")
 
# Creating the menubar.
menuBar = wx.MenuBar()
menuBar.Append(filemenu,"File") # Adding the "filemenu" to the MenuBar
frame.SetMenuBar(menuBar)  # Adding the MenuBar to the Frame content.
frame.Show()
 
app.MainLoop()

A menu in wxPython is simple a wx.MenuBar().

This menu alone will not do anything, it needs to have several sub-menus such as a File menu. A sub-menu can be created with wx.Menu() which in turn has several items.

Finally, we set the frame’s menubar to the menubar we created.

wxPython has some default ids such as wx.ID_ABOUT and wx.ID_EXIT, which are both just integers. You can define your own ids as we did (101, 102).

PyQT Menu

PyQt4 menus appear in the top of the window bar. A menu gives the user control over the application and is often location in the top of the window.

The QMainWindow class creates the main application window. This class has a method named menuBar() which adds the title bar.

Menus can be added to the title bar using addMenu(). Inside each menu you can add a command using the addAction method.

PyQt4 menubar

This code will add a menu to your qt4 app:

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

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

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

# Set window size.
w.resize(320, 240)

# Set window title
w.setWindowTitle("Hello World!")

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

# Add 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)

# Show window
w.show()

sys.exit(a.exec_())
