Problem to declare a stl map - Q_DECLARE_METATYPE

[Althor]

Hi,
I have a problem with Q_DECLARE_METATYPE

I´m trying to declare the type map<string,string> to use it at signals and slots, but because of the type contains a comma I get the following error:

macro "Q_DECLARE_METATYPE" passed 2 arguments, but takes just 1

How could I declare that type?

Thanks in advance.
Regards.

Try using a typedef.

I´ve tried it already but it doesn´t work

Hi

The first code:

Q_DECLARE_METATYPE(QMap<QString, QString>);

Q_DECLARE_METATYPE(QMap<QString, QString>);

To copy to clipboard, switch view to plain text mode 

The code using typedef:

typedef QMap<QString, QString> myQMap;
Q_DECLARE_METATYPE(myQMap);

typedef QMap<QString, QString> myQMap;
Q_DECLARE_METATYPE(myQMap);

To copy to clipboard, switch view to plain text mode

Hi
The problem is solved. I needed to include <QMetaType> to use typedef.
