[Sugar-devel] [PATCH sugar] Fix drag and drop to the clipboard - SL #3811

[Manuel Quiñones]

2012/8/21 Manuel Quiñones <manuq at laptop.org>:
> gtk.gdk.DragContext.get_source_widget returns None if the drag is not
> made within the same application.

pygtk documentation for reference:
http://www.pygtk.org/docs/pygtk/class-gdkdragcontext.html#method-gdkdragcontext--get-source-widget

This is enough test to say that
> it's not an internal drag.  The gtk.Viewport comparison is left as
> fallback.
