The following piece of code demonstrates my problem. Where am I doing wrong? Thanks for any help.

use warnings; use strict;

package MyApp;
use Wx qw(:everything);
use base 'Wx::App';

#Loads a 16x16 BMP image
my $bmp = Wx::Bitmap->new("exit.bmp",wxBITMAP_TYPE_BMP); 

sub OnInit {

    my $frame = Wx::Frame->new(undef,-1,'Menu Icon Test');    
        
    # Creates menus
    my $menu1 = Wx::Menu->new();
    my $menu1item = $menu1->Append(wxID_EXIT, "Exit");    
    
    # I'm trying to set menu item icon here...
    # but the image does not show as expected
    $menu1item->SetBitmap ( $bmp );
    
    # Creates menu bar
    my $menubar   = Wx::MenuBar->new();
    $menubar->Append($menu1, "File");
    
    # Attach menubar to the window
    $frame->SetMenuBar($menubar);
        
    $frame->Show();    
}
  
MyApp->new->MainLoop;
