Hi Monks

Im using the next code for text box:

my $mp = MainWindow->new(title=>"Project List");

my $mp1 = $mp -> Frame;
$mp1->Label(    -text=>'For Help...',
        -font => 'bold',
        -relief => 'sunken',
        -height => '1.5',
        -background => 'lightblue')->pack(-side=>"top",-fill=>"both",-
+anchor=>"w");
$mp1 -> pack;
my $mp2 = $mp -> Frame;
$mp2->Button(    -text => 'Cancel',
        -background => 'lightgreen',
        -command =>\&Escape)->pack(-side=>"right",qw/-padx 50 -pady 2/
+);    
$mp2->Button(    -text => 'OK',
        -background => 'lightgreen',
        -command =>[$mp => 'destroy'])->pack(-side=>"right",qw/-ipadx 
+8 -pady 2/);    
$mp2 -> pack;
my $mp3 = $mp1 -> Frame;
$listbox = $mp3->Scrolled("Listbox",
            "-width" => 35,
            "-height" => 20,
            "-scrollbars" => 'sw',
            "-background" => 'lightyellow');
#open(FILE,"K:\\SHIHAN\\ENV_LIST.txt") or warn "$!\n";
open(FILE,"K:\\Project_List.txt") or warn "$!\n";
while ($line=<FILE>)
    {
        chomp ($line);
        if ( $line =~ '^[1-9]')
        { $listbox-> insert('end',"$line");}
    }
close (FILE);

$listbox-> bind ('<Motion>',\&getNumFlow);
$listbox-> bind ('<Double-1>',sub{getNumFlow(); $mp->destroy;});
$listbox->configure(-yscrollcommand =>['set',$scroll]);
$listbox->pack(-side=>'left',-fill => 'both');
$text2 = $mp3->Text('-width'=>40,'-height'=>2)->pack; 
$mp3 -> pack;

I'm using a '<Motion>' since I can't use any thing else
when I tryed to finde something to react
to a single mouse click I kept getting errors.
Please help me find the right command, since for this even the black book didn't help.

Thanks Ahead
