Did you read QRegExp class reference [developer.qt.nokia.com] ?

Qt libraries are not bound with Qt Creator so you can use QRegExp with any IDE.

Okay, thanks for linking me there. I have a question about setting QRegExp values though, because it seems that you can’t set them using the ‘=’ sign. For example, this works:

QRegExp regexp1(”^[0-9]*$”);

..but this doesn’t..

QRegExp regexp1 = “^[0-9]*$”;

Are there any reasons why they don’t work? And since I’m used to using an ‘=’ sign to set my values, is there any way I can still set them using the ‘=’ operator?

What’s wrong with using setPattern? A regular expression is not a string.

What is setPattern and how do I use it?

I repeat myself – did you read the documentation? setPattern is member function of QRegExp class which allows you to, obviously, set pattern.

In particular, have a look at the Code Examples [developer.qt.nokia.com] section, which I think probably has the simple sort of regex examples you are looking for (assuming you already know a bit about regular expressions, and are just looking for info on implementing them using QRegExp).

Just to be absolutely clear here… have a look at this:
