It supports my assumption that QTextDocument should not be set. Unfotunately I can't derive from BaseTextDocument, because the other class (the one derived from QTextDocument) is already used a lot within other code. I would have to rewrite everything. What I could do is to synchronize the both documents when one is changed, i.e. listen to the contentsChanged SIGNAL of the one document and then make something like doc->setPlainText(mDocToSyncWith->plainText()). _______________________________________________ Qt-creator mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/qt-creator
