A more sophisticated container is a ~box~. It allows you to place, or ~pack~, more than one widget inside a simple container. There are horizontal (*GtkHBox*) and vertical (*GtkVBox*) boxes that pack their widgets correspondingly. First, create a new box: ]]> Then place some widgets into it using either %pack_start()% method (packs left-to-right for HBox and top-to-bottom for VBox) or %pack_end()% method (vice versa). pack_start($child, $expand = true, $fill = true, $padding = 0); ?>]]> You can nest the boxes to any degree, thus creating complex containment patterns.
