Python – MenuBars in wxPython

One of the most important part in a GUI is a menubar, which are used to perform various operations on a Window. In this article we will learn how to create a menubar and add menu item to it. This can be achieved using MenuBar() constructor and Append() function in wx.MenuBar class.

Syntax for MenuBar() constructor:

wx.MenuBar(style=0)

Syntax for Append() function:

wx.MenuBar.Append(self, menu, title)

Parameters:

Parameter	Input Type	Description
menu	wx.Menu	The menu to add. Do not deallocate this menu after calling Append .
title	string	The title of the menu, must be non-empty.

Code Example:

# import wxPython
import wx


class Example(wx.Frame):

    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)

        self.InitUI()

    def InitUI(self):
        # create MenuBar using MenuBar() function
        menubar = wx.MenuBar()
        fileMenu = wx.Menu()
        # add menu to MenuBar
        menubar.Append(fileMenu, '&Menu# 1')
        self.SetMenuBar(menubar)

        self.SetSize((300, 200))
        self.SetTitle('Menu Bar')
def main():

    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()


if __name__ == '__main__':
    main()
