Mhh, then I must be doing something wrong, here is my code example:
main.cpp:
#include <QCoreApplication>
#include <QMetaMethod>
#include <QDebug>
#include "tagclass.h"
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
auto obj = new TagClass();
for (int i = 0; i < obj->metaObject()->methodCount(); i++) {
qDebug() << "name: " << obj->metaObject()->method(i).name() << ", tag:
"
<< obj->metaObject()->method(i).tag();
}
return a.exec();
}
tagclass.h:
#ifndef TAGCLASS_H
#define TAGCLASS_H
#include <QObject>
#define MYTAG // bla bla
class TagClass: public QObject
{
Q_OBJECT
public:
explicit TagClass(QObject * parent = 0) : QObject(parent) {}
public slots:
MYTAG void testFunc() {}
};
#endif // TAGCLASS_H
That should, as far as I understand, print the name and the tag of each
invokable function of TagClass, but on my system (Win7x64 + Qt5.0.1x86) no tag
is being printed for testFunc() :(
