I assume you are talking about that last line.

area.window.set_cursor(dk::Cursor::PENCIL)

What that means is:

  1. send the message window to the object referenced by the variable
area (which in the above code would be an instance of
Gtk::DrawingArea.  This will return a result object.

  2. send the result object which was returned in step 1 the message
set_cursor with the argument dk::Cursor::PENCIL
