[xml-dev] Saving additional style:paragraph-properties attributes

[Graeme Lunt]

Hi,

I am new to open office development and am looking for some help/guidance on
how to save additional paragraph property attributes into an XML document.

I want to associate a security classification (e.g. "unclassified",
"restricted") with a style in Writer.
I have successfully updated the user interface to allow the setting of the
classification but now want the value to be saved/restored into the
XML document (specifically "styles.xml").

My understanding (or mis-understanding) is that this is done with property
names.

I have defined the name "SecLblClass" in
sw/source/core/unocore/
unoprnms.cxx:

       /* 0739 UNO_NAME_SECLBL_CLASS */ {MAP_CHAR_LEN("SecLblClass")},

which is mapped to the associated attribute in
sw/source/core/unocore/unomap.cxx:

       #define COMMON_CRSR_PARA_PROPERTIES_WITHOUT_FN_O1
       ...
       SW_PROP_NMID(UNO_NAME_SECLBL_CLASS), RES_PARATR_SECLBL_CLASS,
CPPUE2T(CPPUTYPE_INT16), PropertyAttribute:MAYBEVOID, 0

The attribute is defined in sw/source/core/bastyp/init.cxx:
       _InitCore()
       ...
       aAttrTab[ RES_PARATR_SECLBL_CLASS - POOLATTR_BEGIN] = new
SfxUInt16Item (RES_PARATR_SECLBL_CLASS, 0);

Then to get this attribute saved into the document, I have just added the
name to the list of paragraph properties in xmloff/source/text/txtprmap.cxx:

       aXMLParaPropMap[]
       ...
       MP_E ("SecLblClass", X841, X841_LABEL, XML_TYPE_NUMBER16, 0)

The X841 namespace is also configured and can be successfully written to the
style.xml.

However, this does not seem to be sufficient for the classification to be
written to the styles.xml.

Can anyone point me at any appropriate examples/documentation, or point out
any steps I am missing?

Thanks,

Graeme
