void close_app(GtkWidget* widget,gpointer user_data) {
 gtk_main_quit();
}
int main (int argc, char **argv) {
 GtkBuilder *gtkBuilder;
 GtkWidget *mainwin;
 gtk_set_locale();

 gtk_init (&argc, &argv);

 gtkBuilder= gtk_builder_new();
 gtk_builder_add_from_file(gtkBuilder,"test2.glade",NULL);
 gtk_builder_connect_signals ( gtkBuilder, NULL );
 mainwin= GTK_WIDGET(gtk_builder_get_object(gtkBuilder,"window1"));
 g_object_unref ( G_OBJECT(gtkBuilder) );

 gtk_widget_show_all ( mainwin );

 gtk_main ();

    You have nothing in the empty spaces in your HBox and VBox. If there are no other widgets taking up the space, then your button will expand to fill all available space. Put some other widgets in your window if you don’t want the button to fill it. Sizing and placement work differently in GTK than they do in other toolkits, the idea is to build a user interface that still looks good when the user resizes the window or when the UI strings change length because the user is using your application in another language.

    See the relevant section of the GTK tutorial or this other tutorial.
