Catching all Signals from widget in QTest

Hi!

I need to catch all signals emitted from a widget using QSignalSpy (or something else), is there a way to do that? It can by only number of those signals without any other info.

You can list all signals of a type by iterating over the methods of its QMetaObject and checking for QMetaMethods for signals.

You could then create a list of signal spys, each connected to one signal, or connect all signals to a custom slot in a receiver object.

Cheers,

If somebody want to know how to do that I paste my code.

Code:

---

#include <QSignalSpy>
 
class QAllSignalSpy : public QList<QSignalSpy*>
{
 
public:
    explicit QAllSignalSpy(QObject *parent){
        QObject *object = parent;
        const QMetaObject *me = object->metaObject();
        int metaCount = me->methodCount();
        for(int i = 0;i<metaCount;i++){
            QMetaMethod mm = me->method(i);
            if (mm.methodType() == QMetaMethod::Signal){
                QString method = QString::number(2)+ mm.methodSignature().constData();
                this->append( new QSignalSpy(object, method.toLatin1().constData() ) );
            }
        }
    }
 
    int signalCount(){
        int all = 0;
        for(int i=0;i<this->size(); i++)
            all += this->at(i)->count();
        return all;
    }
};

enjoy! ;)

I have just published a tiny header-only library which does exactly this: QSignalInspector
