Hey Vitali,
What you may have failed to do is to look at the lines on which the
SOFT_ASSERT is failing. They look like this:
> BaseTextDocumentLayout *documentLayout =
> qobject_cast<BaseTextDocumentLayout*>(doc->documentLayout());
> QTC_ASSERT(documentLayout, return);
So what you need to do is for your text document is to make sure it has
this custom layout subclass set on it as well. This code is found in the
BaseTextDocument constructor:
> BaseTextDocumentLayout *documentLayout = new
> BaseTextDocumentLayout(d->m_document);
> d->m_document->setDocumentLayout(documentLayout);
I hope that may help you.
Regards,
Bjørn
