+    \class QDeclarativePropertyMap
+  \since 4.7
+    \brief The QDeclarativePropertyMap class allows you to set key-value pairs that can be used in bindings.
+
+    QDeclarativePropertyMap provides a convenient way to expose domain data to the UI layer.
+    The following example shows how you might declare data in C++ and then
+    access it in QML.
+
+    Setup in C++:
+    \code
+    //create our data
+    QDeclarativePropertyMap ownerData;
+    ownerData.insert("name", QVariant(QString("John Smith")));
+    ownerData.insert("phone", QVariant(QString("555-5555")));
+
+    //expose it to the UI layer
+    QDeclarativeContext *ctxt = view->bindContext();
+    ctxt->setProperty("owner", &data);
+    \endcode
+
+    Then, in QML:
+    \code
+    Text { text: owner.name }
+    Text { text: owner.phone }
+    \endcode
+
+    The binding is dynamic - whenever a key's value is updated, anything bound to that
+    key will be updated as well.
+
+    To detect value changes made in the UI layer you can connect to the valueChanged() signal.
+    However, note that valueChanged() is \bold NOT emitted when changes are made by calling insert()
+    or clear() - it is only emitted when a value is updated from QML.
+
+    \note It is not possible to remove keys from the map; once a key has been added, you can only
+    modify or clear its associated value.
