Don't you mean "inherits from"?

The Gnome Canvas is a library which provides a GTK+ widget and a bunch
of special "items" that this widget can contain. It supports automatic
redraws and stacking of items. It is very convenient for showing
custom graphical data, e.g. the drawing area of vector drawing
programs, or the grid in a spreadsheet, or the sample display in a
sound sample editor, or games.

So they don't compare. You put a canvas inside a window.

Yep. libgnomecanvasmm in the gnomemm bundle is the C++ wrapper.
