Hi,

the first arg passed to the callback is always the widget the binding was triggered on.

# It handles right-clicks on all entries of the main window
$mwindow->bind("Tk::Entry", "<Button-3>", \&process_context_click
);

# It makes the menu row 'Copy' and calls the sub callback
my $popup = $mwindow->Menu(
    -tearoff           => 0,
    -menuitems         => [
        ['command' => "~Copy", -command => \&callback]
    ]
);

# It must copy the content of the event's entry to the clipboard, but.
+..


{# private scope
my $entry;
sub process_context_click{
    $entry = shift;
    $popup->Popup(
                  -popover     => "cursor",
                  -popanchor     => 'nw'
    )
}
sub callback {
    my $f = $entry; 
    my $g = $f->get();
    $mw->clipboardAppend($g);
}
}
