PHP Editor Review - Gtk Manual Gtk gtkplug constructor

GtkPlug Constructor

GtkPlug (int socket_id);

Creates a new plug which will be connected to the socket specified by the socket_id.

You should make sure that the socket exists when connecting the plug to it. If it does not, the results are undefined. Probably a new GtkWindow will be created and the plug embedded in this window, but you shouldn't rely on that behavior.

The following example creates a plug which connects to the socket created in the constructor example of GtkSocket.

Example 32. Plugging into a socket

<?php
if( !extension_loaded('gtk')) {	
	dl( 'php_gtk.' . PHP_SHLIB_SUFFIX); 
}

if( $GLOBALS['argc'] != 2) {
	die( 'Please pass the socket id as parameter!' . "\r\n");
}

$socketid	= $GLOBALS['argv'][1];

$plug = &new GtkPlug( $socketid);
$plug->set_default_size( 300, 300);
$plug->connect_object('destroy', array('gtk', 'main_quit'));
$plug->set_title( 'plug');

$label	= &new GtkLabel( 'hello from outer space');
$plug->add( $label);
$plug->show_all();

function changeLabel( $objButton, $objLabel, $strLabel) {
	$objLabel->set_text( $strLabel);
}

$window	= &new GtkWindow();
$window->set_title( 'plug controller');
$window->set_default_size( 200, 300);
$window->connect_object('destroy', array('gtk', 'main_quit'));
$vbox = &new GtkVBox();

$arLabels	= array( 'Hello!', 'Yes, I can control you', 'Don\'t believe it, heh?');
foreach( $arLabels as $strLabel) {
	$btn	= &new GtkButton( $strLabel);
	$btn->connect( 'clicked', 'changeLabel', $label, $strLabel);
	$vbox->pack_start_defaults( $btn);
}
$window->add( $vbox);
$window->show_all();

gtk::main();
?>
