[kde-edu]: Problem with QVariant on Rocs project (help request)

[Tomaz Canabrava]

I'v spend all morning working on Rocs trying to implement a multi-document
panel interface,
almost everything is good, but this little piece of code here is somewhat
broken,
my head hurts, anybody can show some light on this, pretty please, with
sugar on top?

void FileArea::createNewScript(){
   KTextEditor::Editor *e = _mainWindow->editor();
   KTextEditor::Document* d = e -> createDocument(0);
   d->setMode("JavaScript");
   addScript(d->documentName(), d);
}

void FileArea::addScript(const QString& name, KTextEditor::Document* data){
   QTreeWidgetItem *scriptItem = new QTreeWidgetItem(_scriptFolder);
   scriptItem->setIcon(0, KIcon("file-new"));
   scriptItem->setText(0, name);
   scriptItem->setData(0, ScriptRole, data);
  _mainWindow->changeActive(scriptItem);
}

void MainWindow::changeActiveScript(QTreeWidgetItem *item){
  KTextEditor::Document *d = item->data(0, FileArea::ScriptRole));
  _scriptingArea->setDocument( d );
  guiFactory()->addClient(_scriptingArea->view());
}

ERROR:

cannot convert 'QVariant' to 'KTextEditor::Document*' in initialization
the line   KTextEditor::Document *d = item->data(0,
FileArea::ScriptRole)); gives me a QVariant,
I'v tried to qobject_cast<KTextEditor*>(item->data(0,
FileArea::ScriptRole)); but also without luck.

Anybody can give-me some light? i'm stuck here almost all morning.
