+\class QDeclarativeListReference
+\brief The QDeclarativeListReference class allows the manipulation of QDeclarativeListProperty properties.
+
+QDeclarativeListReference allows programs to read from, and assign values to a QML list property in a
+simple and type safe way. A QDeclarativeListReference can be created by passing an object and property
+name or through a QDeclarativeProperty instance. These two are equivalant:
+
+\code
+QDeclarativeListReference ref1(object, "children");
+
+QDeclarativeProperty ref2(object, "children");
+QDeclarativeListReference ref2 = qvariant_cast<QDeclarativeListReference>(ref2.read());
+\endcode
+
+Not all QML list properties support all operations. A set of methods, canAppend(), canAt(), canClear() and
+canCount() allow programs to query whether an operation is supported on a given property.
+
+QML list properties are typesafe. Only QObject's that derive from the correct base class can be assigned to
+the list. The listElementType() method can be used to query the QMetaObject of the QObject type supported.
+Attempting to add objects of the incorrect type to a list property will fail.
+
+Like with normal lists, when accessing a list element by index, it is the callers responsibility to ensure
+that it does not request an out of range element using the count() method before calling at().

- \qmlclass Connection QDeclarativeConnection
- \since 4.7
- \brief A Connection object describes generalized connections to signals.
-
- When connecting to signals in QML, the usual way is to create an
- "on<Signal>" handler that reacts when a signal is received, like this:
-
- \qml
- MouseArea {
- onClicked: { foo(x+123,y+456) }
- }
- \endqml
-
- However, in some cases, it is not possible to connect to a signal in this
- way. For example, JavaScript-in-HTML style signal properties do not allow:
-
- \list
- \i connecting to signals with the same name but different parameters
- \i conformance checking that parameters are correctly named
- \i multiple connections to the same signal
- \i connections outside the scope of the signal sender
- \i signals in classes with coincidentally-named on<Signal> properties
- \endlist
-
- When any of these are needed, the Connection object can be used instead.
-
- For example, the above code can be changed to use a Connection object,
- like this:
-
- \qml
- MouseArea {
- Connection {
- signal: "clicked(x,y)"
- script: { foo(x+123,y+456) }
- }
- }
- \endqml
-
- More generally, the Connection object can be a child of some other object than
- the sender of the signal:
-
- \qml
- MouseArea {
- id: mr
- }
- ...
- Connection {
- sender: mr
- signal: "clicked(x,y)"
- script: { foo(x+123,y+456) }
- }
- \endqml

+ \qmlclass Connections QDeclarativeConnections
+ \since 4.7
+ \brief A Connections object describes generalized connections to signals.
+
+ When connecting to signals in QML, the usual way is to create an
+ "on<Signal>" handler that reacts when a signal is received, like this:
+
+ \qml
+ MouseArea {
+ onClicked: { foo(...) }
+ }
+ \endqml
+
+ However, in some cases, it is not possible to connect to a signal in this
+ way, such as:
+
+ \list
+ \i multiple connections to the same signal
+ \i connections outside the scope of the signal sender
+ \i connections to targets not defined in QML
+ \endlist
+
+ When any of these are needed, the Connections object can be used instead.
+
+ For example, the above code can be changed to use a Connections object,
+ like this:
+
+ \qml
+ MouseArea {
+ Connections {
+ onClicked: foo(...)
+ }
+ }
+ \endqml
+
+ More generally, the Connections object can be a child of some other object than
+ the sender of the signal:
+
+ \qml
+ MouseArea {
+ id: area
+ }
+ ...
+ Connections {
+ target: area
+ onClicked: foo(...)
+ }
+ \endqml
