GtkList Constructor
GtkList (void);
Creating a GtkList widget is straightforward, populating it slightly less so. Each item added to the list container must itself be contained in a GtkListItem. In its simplest and most common form, all that means is that the GtkListItem is created with a label, the text content of which will be displayed in the list.
<?php
if( !extension_loaded('gtk')) {
dl( 'php_gtk.' . PHP_SHLIB_SUFFIX);
}
function echo_it($list, $listitem) {
/* collect the text from the selected list item's label */
$listlabel = $listitem->child;
/* filter list items according to child object type */
if($listlabel->get_name() == 'GtkLabel') {
$name = $listlabel->get();
$label = &new GtkLabel("You chose $name just now");
/* create a popup window and display a message relevant to selected item */
$popup = &new GtkWindow(GTK_WINDOW_POPUP);
$popup->set_uposition((gdk::screen_width()/2)+50,
(gdk::screen_height()/3));
$popup->add($label);
$popup->show_all();
/* connect the list item's own deselect signal (not the list's) */
$listitem->connect_object('deselect', create_function('$popup',
'$popup->destroy();'), $popup);
}
else gtk::main_quit();
}
$window = &new GtkWindow(GTK_WINDOW_DIALOG);
$window->set_position(GTK_WIN_POS_CENTER);
$window->connect_object('destroy', array('gtk', 'main_quit'));
$list = &new GtkList();
/* the contents of this array will populate the list */
$fill = array('Angela', 'Belinda', 'Carolyn', 'Danike', 'Etha', 'Fiona',
'Gertraud', 'Heidi', 'Jessica', 'Kirstin', 'Lorinda', 'Marianne');
foreach(range(0, count($fill)-1) as $i)
$listitem[] = &new GtkListItem($fill[$i]);
$list->append_items($listitem);
$enditem = &new GtkListItem();
/* a list item is also a container */
$button = &new GtkButton('Close');
$enditem->add($button);
/* there is no way to append() a single item - but GtkList is a container
widget, so it's okay to use add() */
$list->add($enditem);
$list->connect('select-child', 'echo_it');
$list->show_all();
$window->add($list);
$window->show_all();
gtk::main();
?>
