I'm not sure, is it the default behavior of an widget to get the results for 
all these functions from its children?
What is displayed incorrect? On my computer in my version it diplays correct - 
exacltly like the c++ version. Funny is that the preview looks little bit 
different from the version in the edit mode. In the preview there is no space 
between the button and the lineedit. But this is the same in the C++ version.

In what way is QListView a "compound" widget? Do you mean QListViewItem or 
QListViewPrivate as part? Both don't have singals/slots.

You have write access to the pykde.sf.net cvs as developer. 
Just import qtdesinger
http://sourceforge.net/docman/display_doc.php?docid=14033&group_id=1#commandimport
http://sourceforge.net/cvs/?group_id=61057
and add me as developer for pykde. 
If you don't want to add me as a developer to pykde, I can create a new 
project for the plugin. If you don't want to import it, I'll do after you 
send it me and added me as developer. Of course we don't have to use cvs, but 
I think this would make it a lot easier (and would reduce traffic on the 
mailinglist).
