<![CDATA[Use regex within C++ program]]>Hello to all,

I have to add a GUI to a C++ program that I'm working on. I'm trying to use regex in the C++ program, but I've found
that only Microsoft Visual Studio 2012 compiler supports Regex for C++.

Should I do the C++ code in MSVisual Studio and once finish use my C++ source code to add the GUI in Qt or how can I do?

Thanks in advance for the answer.

Since QRegExp is buggy and not complete and not maintained anymore.
QRegularExpression in contrary is a implementation of full Perl-compatible regular expressions in Qt.

Thanks for your answer.

I'm new to Qt and I'd like to know if having my current C++ code I can do something like below:

My code looks like this and whithin while loop is where I need to a call to a function to parse a string using regex .

So, can I include the QRegExp code inside my C++ code or the QRegExp code should go in another file and I need to call QRegExp function from C++ code? if yes, how?

@#include <iostream>
.
.
function1 ()
//My original C++ code

function2 (){
//My original C++ code
}

My_RegexFunction(Input) {
// Qt QRegExp code

}

int main () {
.
..
//My original C++ code

while () {

Myvar=My_RegexFunction(Input);
}
}@

Thanks in advance for the help.

And by using it, you gain portability at no extra cost! =D
