Greetings Monks!

I found this code on how to make a toplevel always stay on top:

use strict;
use Tk;
use Tk::Balloon;
use Win32::API;

my $mw = new MainWindow;
use vars qw/$Button/;

$mw->Frame(-width=>200, height =>25);
$mw->update;
  Win32::API->new("user32","SetWindowPos",[qw(N N N N N N
N)],'N')->Call(hex($mw->frame()),-1,0,0,0,0,3);

$Button=$mw->Button(-text => "Button",
        -command => sub {
                &do_something;
            })
        ->pack();

my $balloon = $mw -> Balloon(-balloonposition => 'mouse',
-initwait => 10, -bg => 'white');
$balloon -> attach($Button, -balloonmsg => "Button");

MainLoop;

sub do_something {

    #sleep(10);
}

in this node, and it provided all that I needed to make my MainWindow always stay on top. However when I attach Balloon popups to the MainWindow they appear behind the MainWindow. Execute the code above for an example.

Anyone knows how to work around this?

Cheers nubb

    Your hexa hwnd is not the good one :)
    Here your script with a little update

    Have a nice day :)
    use Tk;
use Tk::Balloon;
use Win32::API;
use vars qw/$Button/;

my $mw = new MainWindow;
$id_mw = $mw->id;

$mw->Frame(-width=>200, height =>25);
$mw->update;
Win32::API->new("user32","SetWindowPos",
[qw(N N N N N N N)],'N')->Call(hex($id_mw),-1,0,0,0,0,3);

$Button=$mw->Button(-text => "Button",
                    -command => sub {
                   &do_something;
                 })->pack();

my $balloon = $mw -> Balloon(-balloonposition => 'mouse',
-initwait => 10, -bg => 'white');
$balloon -> attach($Button, -balloonmsg => "Button");


MainLoop;
sub do_something {
    #sleep(10);
