Code Example 1:

import wx 
  
  
class Example(wx.Frame): 
  
    def __init__(self, *args, **kwargs): 
        super(Example, self).__init__(*args, **kwargs) 
  
        self.InitUI() 
  
    def InitUI(self): 
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH) 
  
        self.menubar = wx.MenuBar() 
        self.fileMenu = wx.Menu() 
        self.item = wx.MenuItem(self.fileMenu, 1, '&Check') 
        self.fileMenu.Append(self.item) 
  
        # print the background colour of menu item 
        print(self.item.GetBackgroundColour()) 
        self.menubar.Append(self.fileMenu, '&File') 
        self.SetMenuBar(self.menubar) 
  
        self.SetSize((350, 250)) 
        self.SetTitle('Icons and shortcuts') 
        self.Centre() 
  
  
def main(): 
    app = wx.App() 
    ex = Example(None) 
    ex.Show() 
    app.MainLoop() 
  
  
if __name__ == '__main__': 
    main()
