Transforming the data from string to integer is the right way to do
it. Drag data is always a string, or just a sequence of bytes. The
drag type tells the target how to interpret the string data, so you
would use different drag types to distinguish UTF-8 and UTF-16, for
instance.
You should be able to drag and drop pixbufs too. Probably someone
here will supply an example you can study. Often MIME types are used
as the drag type strings, so 'image/pixbuf' might be the appropriate
drag type to use here.
Just an addition to Doug's excellent response. In PyGTK 2.6 the
set+pixbuf() and get_pixbuf() methods were added to the SelectionData
class for DND of pixbufs. Also look at the
gtk.target_list_add_image_targets() function and the
gtk.SelectionData.targets_include_image() method for additional help. If
you are using PyGTK 2.4 or lower then it's mcuh harder since you would
have to convert the pixbuf to a string and back to drag and drop it and
you probably can only do pixbuf DND within the same app.
