QTextEdit
can be set to read-only with its property readOnly
. I use QTextEdit
to display a long read-only text, because it can scroll. I also have read-write text, and by choosing the same widget for all long text, my user interface looks even.

An other alternative is QWebView
if you plan to have complexly formatted text.
