Detailed Description

A layout manager for bin-like widgets.

Gtk::BinLayout is a Gtk::LayoutManager subclass useful for creating "bins" of widgets. Gtk::BinLayout will stack each child of a widget on top of each other, using Gtk::Widget::property_hexpand(), Gtk::Widget::property_vexpand(), Gtk::Widget::property_halign(), and Gtk::Widget::property_valign() of each child to determine where they should be positioned.
