note 604 added to gtk.gtkbutton.php

I have tried the example above but it has some errors.


<?php

Function ShowAction($widget, $action) 
{
echo $action."\n"; 
} 

$win=&New GtkWindow(); 
//Old: $button1=&New GtkButton('Not Default");
$button1=&New GtkButton("Not Default");
//Old: $button1->Connect('clicked', howaction', 'Not Default');
$button1->connect('clicked', 'showaction', 'Not Default'); 

$button2=&New GtkButton("Default"); 
$button2->Connect('clicked', 'ShowAction', 'Default'); 
// THIS NEXT LINE IS THE KEY
$button2->Set_Flags(GTK_CAN_DEFAULT); // <===========


$bbox=&New GtkHBox(); 
$bbox->Pack_Start($button1); 
$bbox->Pack_Start($button2); 

$win->Add($bbox);
$win->Show_All();

//Use this function to display the Gtk window adn buttons
gtk::main();
// It seems this has to come AFTER the last "->Add()" call... 
 // <=============

$button2->Grab_Default();
?>
