[reportlab-users] Truncating a flowable to fit a frame

an app of mine produces a periodic newsletter, mostly composed by a set of
fixed size frames that are filled with some flowable content. The "editor"
user has the responsibility of tweaking the content to make it fit in each
Now I'm asked about a different approach, where the content for some of those
"areas" may be arbitrarily long, and the system automatically truncates each
flowable as soon as the related frame is full, possibly leaving some space at
the bottom to add something like 'See <a href="here">full content here</a>'.
A brute force implementation would be something like:
story = [....]
fits = False
while not fits:
flowable = SomeFlowable(story)
if frame.add(flowable, canvas):
story = replace_some_trailing_text_with_ellipsis(story)
I suspect that a slightly better way could use the split() method on the
flowable, maybe passing it the height of the frame corrected to leave space
for the hyperlink.... I will try to understand the logic used for example by
Any hint would be appreciated!
Thanks in advance and best wishes,
