[Okular-devel] Implement ODF export for TextDocumentGenerator

[Brad Hards]

G'day team,

Qt 4.5 offers us an easy way to write an ODF text file from a QTextDocument. A 
few of our generators have such a thing. So here is the easy patch....

This only applies to those deriving from Okular::TextDocumentGenerator. It 
could be applied to Plucker generator, but I don't have any samples that 
work.

Thoughts / comments?

Brad
