Problem You have seen how to place a background image in a GtkWindow as shown in the article How to place a background image in GtkWindow?
Suppose instead of a single background image, you want to have a tiled background image in a GtkWindow as shown below:
Solution
- In PHP-GTK2 (actually it's the underlying GTK), background images are always displayed in tiles.
- So if your background image size is smaller than your application window size, you will find that the background image will always be displayed in tiles — repeating itself in the x- and y- directions.
Sample Code Note: The following image file is required by the sample code below. Please save a copy of the image files and put them in the same directory where you store the sample code.

$window = new GtkWindow();
$window->set_size_request(480, 240);
$window->connect_simple('destroy', array('Gtk','main_quit'));
$window->add($vbox = new GtkVBox());
// display title
$title = new GtkLabel("Place a background image in GtkWindow\n".
" Part 2 - tiled background image");
$title->modify_font(new PangoFontDescription("Times New Roman Bold Italic 10"));
$title->modify_fg(Gtk::STATE_NORMAL, GdkColor::parse("#0000ff"));
$title->set_size_request(-1, 40);
$vbox->pack_start($title, 0);
$vbox->pack_start(new GtkLabel(), 0);
$vbox->pack_start(new GtkLabel("Notice the background image is tiled!"));
$vbox->pack_start(new GtkLabel("It'll keep repeating in the x and y directions."));
// set background image
$pixbuf=GdkPixbuf::new_from_file("sample6_150.png");
