In abiword, formatting stays the same until a new format specification
changes it.

Well what you need to do then is specify the new format at when it starts
via the appendFmt. When it finishes specify the next format also via the
appendFmt. If there is some span of text that does not have one of these
specified style regions, then define a default style that
all these styles drop back to. Then define what this style is before
loading the document. Give it some obvious name like "Word Perfect
Default". When one of these segments finishes, do a appendFmt(addStyle...)
command to set all the AbiWord propeties back to this default
configuration. Then do a appendFmt to give the new set of text
definitions.
Does this make sense? You reset the AbiWord text definitions via a style
definition. AbiWord has a builtin style called "Normal Clean" that resets
most properties to boring, sane, values. Have a look at pt_PT_Styles.cpp
to
see.
Also define some user defined styles in in Abiword for a document to see
how the file format works.
Let me know if you need more clarifications.
Cheers
Martin
