Objective
Suppose now you want the button to be exactly of the size 96 x 36.
Overview
The concept is exactly the same as explained in the previous article. Instead of one button, we just continuously add three buttons using a for-next loop, each time packing the button into the hbox with expand set to false.

$window = new GtkWindow();
$window->connect_simple('destroy',array('Gtk','main_quit'));
$window->set_size_request(400, 100);
$vbox = new GtkVBox();
$window->add($vbox);
$hbox = new GtkHBox();
for ($i=1; $i<=3; ++$i) {
$button = new GtkButton('button'.$i);
$button->set_size_request(60,32); // note 1
$button->connect('clicked', 'on_click'); // note 2
$hbox->pack_start($button, false); // note 3
$hbox->pack_start(new GtkLabel(), false); // note 4
}
$vbox->pack_start($hbox, false);
