You need the Class package that you have to associate with the RichEdit widget.
Then you can bind the KeyPress event.
This code below works form me with Win32::GUI 0.502 but could have problems with more recent versions.

I hope dada could give us a more complete answer :)
use strict; use Win32::GUI; my $win = new Win32::GUI::Window( -name => "Window", -text => "Test", -width => 200, -height => 100, -left => 200, -top => 100, -minsize => [200, 100], ); my $TextClass = new Win32::GUI::Class( -name => "_Editor", -extends => "RichEdit", -widget => "RichEdit", ); my $SearchText = $win->AddRichEdit ( -class => $TextClass, -left => 10, -top => 10, -width => 170, -height => 52, -text=>"", -name=>"searchtext", ); sub searchtext_KeyPress { my($key) = @_; if ($key == 13) { print "Enter!\n"; } return 1; } sub Window_Terminate { exit; return -1; } $win->Show(); Win32::GUI::Dialog();

UPDATE:

Above code works with RichEdit. If you want to recognize enter press on a Textfield, recent rumours on the Win32::GUI mailing list, point me to this:
use strict; use Win32::GUI; my $win = new Win32::GUI::Window( -name => "Window", -text => "Test", -width => 200, -height => 100, -left => 200, -top => 100, -minsize => [200, 100], ); my $SearchText = $win->AddTextfield ( -left => 10, -top => 10, -width => 170, -height => 52, -text=>"", -name=>"searchtext", -multiline=>1, ); sub searchtext_Change{ my $rtest = 0; my $input =''; $input=$SearchText->Text(); $rtest = $input=~/\r\n$/; if($rtest){print "Enter!\n";} } sub Window_Terminate { exit; return -1; } $win->Show(); Win32::GUI::Dialog();
Thanks to John Rogers to show us the trick (with a little fix from me ;) )
