Introduction
This example covers a container called the GtkHButtonBox. The GtkHButtonBox container is used to group buttons together in a horizontal box from left to right. From what I can tell, the GtkHButtonBox is designed to contain only buttons. However, you can pack other widgets such as GTKLabel widgets and it seems to work fine. Since GtkHButtonBox seems to accept widgets other than buttons, it is essentially the same as the GtkHBox container except that GtkHButtonBox places more space between the widgets by default that GtkHBox. In this example, the GtkHBox contains five GtkButton widgets.
