Questions about KPart integration inside KHTML

[Greg Langmead]

Hi.  I have a couple of specific technical questions about the 
capabilities of KPart within Konq/KHTML, and I'm hoping someone here 
can help me or point me to the right documentation.  The pages I've 
looked at don't quite address my particular concerns.

First, is it possible to have a KPart set up to handle certain XML 
nodes, rather than entire files?  All the examples in the docs are 
centered around plug-ins and image viewers for separate files, but I'm 
interested in extending the browser to support XML data that it doesn't 
support natively (good examples would be SVG and MathML).  My KPart 
would need to be somehow activated to render these nodes, and have 
access to the node's XML.  If necessary, I could add the constraint 
that the nodes I want to render are all given some specific namespace 
prefix in the XML source.

Secondly, how tightly integrated can a KPart be inside a KHTML widget?  
To do a good job of integrating, I'd need to be able to query the 
ambient KHTML widget for the current font at each of my KPart's 
instances, as well as the current font size and text baseline.  Again, 
the docs seem focused on plugins, which are loosely integrated and 
don't depend on their environment.

Finally, it seemed from the docs like a KPart can determine its own 
size, and I wanted to verify that this is the case.  Netscape plugins 
run in a rectangular area specified directly in the HTML but my KPart 
would need to tell the page renderer what its size is.

Thanks for any pointers.
