in thread making a GUI for a web client

Thanks for the reply. I may be going the wrong way about this but using the code below doesn't update the label text, it produces another label.

#! c:\perl\bin -w use strict; use Tk; my $mw=new MainWindow; $mw->minsize(qw(250 150)); $mw->title(" Tk Test 1 "); my $body=$mw->Frame(-background=>'cyan')->pack(side=>'bottom', -fill=> +'x'); my $fr1=$body->Frame(-background=>'magenta')->pack(side=>'top', -fill= +>'x'); my $txt='hi'; $fr1->Label(-textvariable=>\$txt, -background=>'yellow', -foreground=> +'red')->pack(-fill=>'y'); sleep 5; change('foo', $fr1, $mw); sleep 5; change('bar', $fr1, $mw); MainLoop(); sub change { my ($txt, $fr1, $mw)=@_; $fr1->Label(-textvariable=>\$txt, -background=>'yellow', -foregrou +nd=>'red')->pack(-fill=>'y'); $mw->update; }
