Looking for help for clipboard in Math

[Regina Henschel]

Hi all,

I struggle with the clipboard. My goal is to import MathML in module 
Math from clipboard, similar as it is imported from file. But I'm stuck. 
Therefore some questions:

(1)
Has someone tried such already and found, that it is not possible?

(2)
The comments in file exchange.cxx refer to a document "CLIP.SDW". Has 
someone this document and can provide it?

(3)
I have added a .uno command which is executed in 
SmViewShell::Execute(SfxRequest& rReq)

My current attempt looks like this:

TransferableDataHelper aDataHelper( 
TransferableDataHelper::CreateFromSystemClipboard(GetEditWindow()) );
SotFormatStringId nId;
DataFlavorExVector* pFormats;
pFormats = &aDataHelper.GetDataFlavorExVector();
DataFlavorExVector::iterator aIter( 
((DataFlavorExVector&)*pFormats).begin() ),
                                 aEnd( 
((DataFlavorExVector&)*pFormats).end() );
while ( aIter != aEnd )
{
     nId = (*aIter).mnSotId;
...
     aIter++;
}

I get some nId-values and for some of them I can get a stream and can 
look at the content. But the clipboard content, which is generated by 
the Windows program "Math Input Control" (mip.exe) is not noticed. But I 
see that the clipboard has a content "MathML" and a content "MathML 
Presentation" using the clipboard viewer "Free Clipboard Viewer 2.0". 
Why do I get no nId for it?

(4)
The numbers I get in nId are those from the list in exchange.cxx, and 
for "application/mathml+xml", which is not listed there, I get the next 
one following the list. But how can I get the MimeType or the 
HumanPresentableName for the detected nId? My following try does not 
work, the strings are empty in all cases:

::com::sun::star::datatransfer::DataFlavor aFlavor;
SotExchange::GetFormatDataFlavor( nId, aFlavor ) )
String sHumanPresentableName(aFlavor.HumanPresentableName);
String sMimeType(aFlavor.MimeType);

(5)
I try to use SmViewShell::InsertFrom(SfxMedium &rMedium). It seems to 
work, but when the process arrives at SmXMLImport::endDocument(void), 
the node tree is empty.  Any tips, what I might have missed?

Kind regards
Regina
