public class OffscreenWindow : Window, Implementor, Buildable

GtkOffscreenWindow is strictly intended to be used for obtaining snapshots of widgets that are not part of a normal widget hierarchy.

Since OffscreenWindow is a toplevel widget you cannot obtain snapshots of a full window with it since you cannot pack a toplevel widget in another toplevel.

The idea is to take a widget and manually set the state of it, add it to a GtkOffscreenWindow and then retrieve the snapshot as a XlibSurface or Pixbuf.

GtkOffscreenWindow derives from Window only as an implementation detail. Applications should not use any API specific to Window to operate on this object. It should be treated as a Bin that has no parent widget.

When contained offscreen widgets are redrawn, GtkOffscreenWindow will emit a damage_event signal.
