QRegExp: problem with kleene star respectively '*'
Message 1 in thread
Hello,
i recently encountered problems with QRegExp.
I generated the following regular expression to test, if a QChar is a
digit, whitespace, minus, opening bracket, closing bracket or a comma:
QRegExp valid("[\\d\\s-\\(\\),]");
then i did a
bool result = valid.exactMatch("*");
result is true.
Has anyone an idea why the given regular expression fits also the '*' ?
Did not find a suitable bug report, so possibly this is my mistake.
Thanks in advance.

[...-...] has a special meaning (defining a range).
Maybe that's your problem. If it is, try to move the dash
close to the [ or the ].
