+/*! 
+    \class QSignalSpy
+    \inmodule QtTest
+
+    \brief The QSignalSpy class enables introspection of signal emission.
+
+    QSignalSpy can connect to any signal of any object and records its emission.
+    QSignalSpy itself is a list of QVariant lists. 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)

+    Example:
