[Qt-interest] "indexOfMethod" always return -1 if it's parameter is not a slot or sigal, why

[Yao Huiji]

sorry , I press the send shortcut key unguardedly.

here is my code:

###############  tictac.h     ######################
#ifndef TICTAC_H

#define TICTAC_H

#include <QObject>

class QTimerEvent;

class QString;

class TicTac : public QObject

{

Q_OBJECT

public:

TicTac();

//public slots:

void SayHi();

protected:

void timerEvent(QTimerEvent *event);

};

#endif // TICTAC_H

##################################



#############  main.cpp   #####################

#include <QtCore/QCoreApplication>

#include "tictac.h"

int main(int argc, char *argv[])

{

QCoreApplication a(argc, argv);

TicTac *tictac = new TicTac;

const QMetaObject *meta = tictac->metaObject();

QString str;

if(meta->indexOfMethod("SayHi()") != -1)

{

meta->invokeMethod(tictac,"SayHi",Qt::DirectConnection);

}

else

{

qDebug("No such method!");

}

qDebug(str.toStdString().c_str());

return a.exec();

}
