Example 87. Setting GtkLabel Text with Pango Markup

// Create a window to hold the label.
$window = new GtkWindow();

// Set up the window to close cleanly.
$window->connect_simple('destroy', array('Gtk', 'main_quit'));

// Create a label.
$label = new GtkLabel();

// Set some text with Pango markup.
$label->set_markup('<span color="red">Example</span> Label');

// Add the label to the window.

// Show the window and start the main loop.
This code will produce the window shown below.
