Documentation for QTextCharFormat::setAnchor unclear

If anchor is true, text with this format represents an anchor, and is formatted in the appropriate way; otherwise the text is formatted normally. (Anchors are hyperlinks which are often shown underlined and in a different color from plain text.)

Links are NOT formatted differently from the other text by default (despite documentation claims). The only difference for links is cursor shape above them. To highlight them you ought to use underlining and blue-color format.
