Note that if you have many such top-level entries, like 10,000 or so,
and you set self.canv.showOutline() to show the outline when the doc
is being opened, Acrobat Reader will take ages to show anything at
all. AR 6 is behaving much better than AR 5, although it still can
take a while... So, then you really need a nested outline.

<excerpt>Here's the class I use to create bookmarks. You're probably
right that it

should inherit from ActionFlowable and not just Flowable; this has
always

worked for me anyhow. It would have to be extended further to support
nested

bookmarks.


class Bookmark(Flowable):

    """ Utility class to display PDF bookmark. """


    def __init__(self, title, key):

        self.title = title

        self.key = key

        Flowable.__init__(self)


    def wrap(self, availWidth, availHeight):

        """ Doesn't take up any space. """

        return (0, 0)


    def draw(self):

        # set the bookmark outline to show when the file's opened

        self.canv.showOutline()

        # step 1: put a bookmark on the 

        self.canv.bookmarkPage(self.key)

        # step 2: put an entry in the bookmark outline

        self.canv.addOutlineEntry(self.title,

                self.key, 0, 0)

</excerpt>
