When I use an entry widget in Perl/Tkx, the behavior is not what I expect. Here is sample code: 
use strict;
use Tkx;
Tkx::package_require("tile");
Tkx::package_require("style");

my $mw = Tkx::widget->new(".");
my $text = "abc";
my $entry = $mw->new_ttk__entry(-width => 20, -textvariable => \$text)
+;
$entry->configure(-font => "helvetica 14 bold");
$entry->g_grid(-column => 0, -row => 0, -sticky => 'w');
$entry->configure(-validate => 'all', -validatecommand => \&Entry);

Tkx::MainLoop();

sub Entry
{
    ### Tkx::update();
    print "text = '$text'\n";
    return 1;
}

When I run the script and click in the entry widget, I get text = 'abc' printed, which is what I expect. When I then type '1' in the entry widget, I still get text = 'abc' printed, but I expected to get text = 'abc1'. When I then type '2', I get text = 'abc1', but I expected to see text = 'abc12'. When I click outside of the widget, the correct string is then printed. Is there a way to have the validatecommand get the current value of the textvariable? I've tried changing the -validate value from "all" to other values, but that doesn't help. I've tried adding a call to Tkx::update() (see commented out code), but that doesn't seem to have any affect. Any help would be appreciated.

Thanks,
Dave
