Filtering QStringList with QRegExp is not working[SOLVED]

RolBri

Hey,

I tried to filter a QStringList having entries like these:

pic20150718_060126.jpg
pic20150718_060626.jpg
pic20150718_061126.jpg
pic20150719_061126.jpg

For me just the part 20150718 is interesting.
So I used the expression QRegExp(^pic20150718.+) to filter.
If I now use the indexOf-method of QStringList I always get "-1".

What is the problem with that?
Thank you very much :-)

Hi,

Can you show your code ?

Using strList.indexOf(QRegExp("^pic20150718.*")); works correctly.

On a side note, if you are using Qt 5, you should rather use QRegularExpression

Thank you very much :-)

First I tried to insert the expression like this:

QString date = "20150718";
QString expr = "^pic"+date+".*";
QRegExp exp(expr);

This was not working, but now it works.
I cleaned the whole project and it seems like there was something wrong with the building process :-)
