How to use regex to replace URLs with an HTML link in Qt? -

-

how use qstring::replace detect urls in string , replace them html link, so...

[...].replace(qregexp("???"), "<a href=\"\\1\">\\1</a>")

what should argument qregexp be? end of url should denoted occurrence of whitespace character (such space, \r or \n) or end of string.

the regex should simple: http://, https://, ftp://, etc, followed 1 or more non-whitespace characters, should converted link.

edit: solution used...

[...].replace(qregexp("((?:https?|ftp)://\\s+)"), "<a href=\"\\1\">\\1</a>")

i think (?:https?|ftp)://\\s+ you.

don't forget potentially match invalid urls, that's ok purposes. (a regex matches syntactically valid urls quite complicated construct , not worth effort.)
