Gtk::Layout is similar to Gtk::DrawingArea in that it's a "blank slate" and doesn't do anything but paint a blank background by default. It's different in that it supports scrolling natively (You can add it directly to a Gtk::ScrolledWindow), and it can contain child widgets, since it's a Gtk::Container. However if you're just going to draw, a Gtk::DrawingArea is a better choice since it has lower overhead.
When handling expose_event signals, you must draw to the bin_window Gdk::Window - see get_bin_window() - rather than the normal Gdk::Window - see get_window() - as you would for a drawing area.

This function should only be called after the layout has been placed in a Gtk::ScrolledWindow or otherwise configured for scrolling. It returns the Gtk::Adjustment used for communication between the horizontal scrollbar and layout . See Gtk::ScrolledWindow, Gtk::Scrollbar, Gtk::Adjustment for details.
