$window->connect_simple('destroy', array('Gtk','main_quit'));
$window->add($vbox = new GtkVBox());
// display title

$title->modify_font(new PangoFontDescription("Times New Roman Italic 10"));
$title->modify_fg(Gtk::STATE_NORMAL, GdkColor::parse("#0000ff"));

$hbox = new GtkHBox();
for ($i=0; $i<3; ++$i) {
$button = new GtkButton('');
$button_label = $button->child; // note 1
$button_label->set_text_with_mnemonic('button _'.($i+1)); // note 2
$button->set_size_request(80, 32);
$button->connect('clicked', 'on_click');
$hbox->pack_start($button);
$hbox->pack_start(new GtkLabel(''));
}
$alignment = new GtkAlignment(0.5, 0, 0, 0);

Explanation The example above makes use of the code from How to set the button to the exact size you want - Part 3 - group of buttons? to display the three buttons.
What's new here:
- Get the button label.
- Set the label text with mnemonic. Note the use of underscore to indicate the mnemonic.
You can now press Alt-1, Alt-2, Alt-3 to activate these buttons.
Note
Note that in the article How to add mnemonic to GtkLabel?, we need to use the method GtkLabel::set_mnemonic_widget() to associate each mnemonic to the widget that will be activated.
This method is not required in this example because php-gtk2 is smart enough to automatically associate the mnemonic we set on the button label to its parent (i.e. the button).
