QTextCursor::movePosition and QTextEdit::scrollToAnchor don't work.

Did you remember to set the cursor?

QTextCursor cursor = textEdit->textCursor();
cursor.movePosition(..);
textEdit->setTextCursor(cursor); // maybe you forgot this?

QTextCursor cursor = textEdit->textCursor();
cursor.movePosition(..);
textEdit->setTextCursor(cursor); // maybe you forgot this?

To copy to clipboard, switch view to plain text mode 

Check this thread out. That piece of code gives you the current line number of the cursor. With sligth modifies you can move the cursor to a specific line.
