wxPython Replace() function in wxPython (original) (raw)

Last Updated : 11 May, 2020

Another function in wx.MenuBar class is Replace() function. If we ever want to replace a menu from menubar we use Replace() function. It takes three main parameters that is position of menu we want to replace, menu we want to add, title of new menu.

Syntax :

wx.MenuBar.Replace(self, pos, menu, title)

Parameters :

The title of the menu.

Parameter Input Type Description
pos int The position of the new menu in the menu bar
menu wx.Menu The menu to add.
title string The menu to add.

Let’s create a window with two menu items Menu_one and Menu_two.

Code :

import wx

class Example(wx.Frame):

`` def __init__( self , * args, * * kw):

`` super (Example, self ).__init__( * args, * * kw)

`` menubar = wx.MenuBar()

`` fm1 = wx.Menu()

`` fileitem = fm1.Append( 20 , "one" )

`` fm2 = wx.Menu()

`` fileitem2 = fm2.Append( 20 , "two" )

`` menubar.Append(fm1, '&Menu_one' )

`` menubar.Append(fm2, '&Menu_two' )

`` 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()

Window:

Now lets replace Menu_two with new_Menu.

Code for Replace :

import wx

class Example(wx.Frame):

`` def __init__( self , * args, * * kw):

`` super (Example, self ).__init__( * args, * * kw)

`` menubar = wx.MenuBar()

`` fm1 = wx.Menu()

`` fileitem = fm1.Append( 20 , "one" )

`` fm2 = wx.Menu()

`` fileitem2 = fm2.Append( 21 , "two" )

`` fm3 = wx.Menu()

`` fileitem3 = fm3.Append( 22 , "new" )

`` menubar.Append(fm1, '&Menu_one' )

`` menubar.Append(fm2, '&Menu_two' )

`` self .SetMenuBar(menubar)

`` self .SetSize(( 300 , 200 ))

`` self .SetTitle( 'Menu Bar' )

`` menubar.Replace( 1 , fm3, "new_Menu" )

def main():

`` app = wx.App()

`` ex = Example( None )

`` ex.Show()

`` app.MainLoop()

if __name__ = = '__main__' :

`` main()
