Or you can build the top level C++ stub and install it as a normal KDE app.
Just a shame it doesn't actually work with your app yet :(..

I've been looking at it. What seems to happen is the KFileTreeBranch emits the
signal 'populateFinished(KFileTreeViewItem*)' which is supposed to be
connected to 'slotPopulateFinished(KFileTreeViewItem*)', but the slot is
void KFileTreeBranch::slCompleted( const KURL& url )
kdDebug(250) << "SlotCompleted hit for " << url.prettyURL() << endl;
KFileTreeViewItem *currParent = findTVIByURL( url );
if( ! currParent ) return;
kdDebug(250) << "current parent " << currParent << " is already listed: "
<< currParent->alreadyListed() << endl;
emit( directoryChildCount(currParent, currParent->childCount()));
KFileTreeBranch *KFileTreeView::addBranch(KFileTreeBranch *newBranch)
connect( newBranch, SIGNAL(populateFinished( KFileTreeViewItem* )),
this, SLOT( slotPopulateFinished( KFileTreeViewItem* )));
connect( newBranch, SIGNAL( newTreeViewItems( KFileTreeBranch*,
const KFileTreeViewItemList& )),
this, SLOT( slotNewTreeViewItems( KFileTreeBranch*,
const KFileTreeViewItemList& )));
m_branches.append( newBranch );
return( newBranch );
void KFileTreeView::slotPopulateFinished( KFileTreeViewItem *it )
kdDebug(250) << "KFileTreeView::slotPopulateFinished" << endl;
if( it && it->isDir())
stopAnimation( it );
So the stopAnimation() method is never called. When I try and run it under the
KDevelop debugger it crashes pretty much straight away, and so I haven't been
able to examine the state of the slot/signal connections.
I've improved the qt_invoke code in qtruby Qt.cpp source anyway, so at least
it will be more efficient - I'll check that change in. But for the
'slotPopulateFinished()' in never gets called in qt_invoke() in Kdigest.
