Hi all,

I'm in the process of porting an old application from perl/tk to tkx.
I'm having problems trying to change the state of a menu entry in the application menu.
I thought I should use configure(-state=>'disabled') or 'normal', but it seems I can't get the right pathname to the item I need.

Here is a quick mockup. The exact same code works for enabling/disabling buttons.
#!/usr/bin/perl
use strict;
use warnings;

use Tkx;

my $mw = Tkx::widget->new(".");
my $menu = $mw->new_menu;
  
my $M_file = $menu->new_menu(
     -name => "file",
     -tearoff => 0,
      );

my $UUU=$menu->add_cascade(
      -label => "File",
      -underline => 0,
      -menu => $M_file,
      -state=>'normal',
  );
  $M_file->add_command(
      -label => "New",
      -underline => 0,
      -command => \&new,
  );
  $M_file->add_command(
      -label   => "Exit",
      -underline => 1,
      -command => [\&Tkx::destroy, $mw],
  );

  my $help = $menu->new_menu(
      -name => "help",
      -tearoff => 0,
  );
  $menu->add_cascade(
      -label => "Help",
      -underline => 0,
      -menu => $help,
  );
  $help->add_command(
      -label => "\uManual",
      -command => \&show_manual,
  );


$mw->configure(-menu => $menu);


my $button_test= $mw->new_ttk__button(-text => "test", -command => \&t
+st1);
$button_test->g_grid(-column => 0, -row => 0,   -sticky => "ew");

&Tkx::MainLoop();
exit;

sub tst1 {
  my $st = $UUU->cget(-state);
  $st eq 'normal' ? $UUU->configure(-state =>'disabled') : $UUU->confi
+gure(-state =>'normal');
}

according to
http://docs.activestate.com/activetcl/8.4/tcl/TkCmd/menu.htm
this should be the procedure (in fact, one can set the menu as normal or disabled during creation). But I can't understand how to change it.

any pointers?

thanks
