Each emission of the signal + will append one item to the list, containing the arguments of the signal. + + The following example records all signal emissions for the \c clicked() signal + of a QCheckBox: + + \snippet doc/src/snippets/code/doc_src_qsignalspy.cpp 0 + + \c{spy.takeFirst()} returns the arguments for the first emitted signal, as a + list of QVariant objects. The \c clicked() signal has a single bool argument, + which is stored as the first entry in the list of arguments. + + The example below catches a signal from a custom object: + + \snippet doc/src/snippets/code/doc_src_qsignalspy.cpp 1 + + \bold {Note:} Non-standard data types need to be registered, using + the qRegisterMetaType() function, before you can create a + QSignalSpy. For example: + + \snippet doc/src/snippets/code/doc_src_qsignalspy.cpp 2 + + To retrieve the \c QModelIndex, you can use qvariant_cast: + + \snippet doc/src/snippets/code/doc_src_qsignalspy.cpp 3 + */ + +/*! \fn QSignalSpy::QSignalSpy(QObject *object, const char *signal) + + Constructs a new QSignalSpy that listens for emissions of the \a signal + from the QObject \a object.
