[reportlab-users] Page headings in platypus

[Robert Young]

Thanks - that stopped the crash, but it doesn't actually put headers in
my report. 

The code now does:

story.append(Paragraph(Group1header1,headerstyle))
story.append(DocIf('doc.frame._atTop',Paragraph(continuation1,headerstyl
e)))
story.append(Paragraph(detail line1,detailstyle))
story.append(Paragraph(detail line2,detailstyle))
story.append(Paragraph(detail line3,detailstyle)) 
...
story.append(Paragraph(detail line_n,detailstyle)) 

story.append(Paragraph(Group2header1,headerstyle))
story.append(DocIf('doc.frame._atTop',Paragraph(continuation2,headerstyl
e)))
story.append(Paragraph(detail line1,detailstyle))
story.append(Paragraph(detail line2,detailstyle))
story.append(Paragraph(detail line3,detailstyle)) 
...
story.append(Paragraph(detail line_n,detailstyle))

and so on. Then it does the build:

pdf.build(story, onFirstPage=BuildPage,onLaterPages=BuildPage)

(with BuildPage putting page numbers on each page.

Each detail line paragraph is only one or two lines, so it is rare that
a paragraph will break across a page. I was hoping that each "DocIf"
would put the appropriate continuation header when any of the following
detail lines is at the start of a page. Or is there some sort of
container between "paragraph" and "story" that would be better to use?

Doh! not enough doughnuts today. Frame objects have an _atTop attribute.
