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.

" 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 $pixbuf=GdkPixbuf::new_from_file("sample6_150.png"); list($pixmap,$mask)=$pixbuf-> render_pixmap_and_mask(255); $style = $window->get_style(); $style=$style->copy(); $style->bg_pixmap[Gtk::STATE_NORMAL]=$pixmap; $window->set_style($style); $window->show_all(); Gtk::main(); ?> |
Output
