[reportlab-users] Handling of too long entries in Table

[Willi Richert]

Hi,

I tried the following solution:
- data is a 2-dim array with strings in it
- For each data-element I generate a Paragraph object and see which size it 
is.
- Paragraph has the member getActualLineWidths0() which shall return a list of 
the line widths.

But: When I try to do this I get:
raceback (most recent call last):
  File "movatisreport.py", line 135, in ?
    t = tf.getTable(data)
  File "movatisreport.py", line 85, in getTable
    w=p.getActualLineWidths0()
  File "/usr/lib/python2.2/site-packages/reportlab/platypus/paragraph.py", 
line 737, in getActualLineWidths0
    w.append(self.width - frag.extraSpace)
AttributeError: 'tuple' object has no attribute 'extraSpace'

The frag contains. e.g. the following at runtime:
(177.11000000000001, ['Customer']),
which of course has no extraSpace member.

Is this a bug? If not, is it possible to get the width of the splitted 
paragraph differently?

This problem can't be so difficult.

Thanks,
willi
