Can't initialise variable of type QRegExp

El3ctroGh0st

Hey,

I have a very simple question. I have the following code (it's a header file):

#ifndef PARSER_HPP
#define PARSER_HPP

#include <QObject>
#include <QString>
#include <QRegExp>

class Parser
{
    Q_OBJECT
public:
    Parser() = default;
    Parser(QString str) : searchArgument(str) {}

private:
    QString searchArgument;
    QRegExp rx("(\\d+)");
};

#endif // PARSER_HPP

However, on attempting to compile it, the compiler tells me that it "expected an identifier before string constant" (the QRegExp rx("(\\d+)"); part). I am kind of confused about why it doesn't work, because in the documentation it's stated that you there is a constructor of this type that takes a QString as an argument. Any ideas?

Hi,

When using initialisation in headers, you have to use the assignment operator not the constructor.
