+The Qt object provides useful enums and functions from Qt, for use in all QML
+files. 
 
-creating types:
-\list
-\o hsla
-\o rgba
-\o rect
-\o point
-\o size
-\o vector3d
-\endlist
+\section2 Enums
+The Qt object contains all enums in the Qt namespace. For example, you can
+access the AlignLeft member of the Qt::AlignmentFlag enum with \c Qt.AlignLeft.
+
+For a full list of enums, see the Qt Namespace documentation.
+
+\section2 Types
+The Qt object also contains helper functions for creating objects of specific
+data types. This is primarily useful when setting the properties of an item
+when the property has one of the following types:
 
-manipulating color:
 \list
-\o lighter
-\o darker
-\o tint
+\o Color
+\o Rect
+\o Point
+\o Size
+\o Vector3D
 \endlist
 
-and playing sound:
-\list
-\o playSound
+There are also string based constructors for these types, see \l{basicqmltypes.html}{Qml Types}.
+
+\section3 Qt.rgba(int red, int green, int blue, int alpha)
+This function returns a Color with the specified \c red, \c green, \c blue and \c alpha components. All components should be in the range 0-1 inclusive.
+
+\section3 Qt.hsla(int hue, int saturation, int lightness, int alpha)
+This function returns a Color with the specified \c hue, \c saturation, \c lightness and \c alpha components. All components should be in the range 0-1 inclusive.
+
+\section3 Qt.rect(int x, int y, int width, int height) 
+This function returns a Rect with the top-left corner at \c x,\c y and the specified \c width and \c height.
+\section3 Qt.point(int x, int y)
+This function returns a Point with the specified \c x and \c y coordinates.
+\section3 Qt.size(int width, int height)
+returns as Size with the specified width and height.
+\section3 Qt.vector(real x, real y, real z)
+    This function is intended for use inside QML only. In C++ just create a
+    QVector3D as usual.
+
+    This function takes three numeric components and combines them into a
+    QVector3D value that can be used with any property that takes a
+    QVector3D argument.  The following QML code:
+
+    \code
+    transform: Rotation {
+        id: rotation
+        origin.x: Container.width / 2;
+        axis: vector(0, 1, 1)
+    }
+    \endcode
+
+    is equivalent to:
+
+    \code
+    transform: Rotation {
+        id: rotation
+        origin.x: Container.width / 2;
+        axis.x: 0; axis.y: 1; axis.z: 0
+    }
+    \endcode
+
+
+\section2 Functions
+The Qt object also contains the following miscellaneous functions which expose Qt functionality for use in QML.
+
+\section3 Qt.lighter(color baseColor)
+This function returns a color 50% lighter than \c baseColor. See QColor::lighter() for further details.
+\section3 Qt.darker(color baseColor)
+This function returns a color 50% darker than \c baseColor. See QColor::lighter() for further details.
+\section3 Qt.tint(color baseColor, color tintColor)
+    This function allows tinting one color with another.
+
+    The tint color should usually be mostly transparent, or you will not be able to see the underlying color. The below example provides a slight red tint by having the tint color be pure red which is only 1/16th opaque.
+
+    \qml
+    Rectangle { x: 0; width: 80; height: 80; color: "lightsteelblue" }
+    Rectangle { x: 100; width: 80; height: 80; color: Qt.tint("lightsteelblue", "#10FF0000") }
+    \endqml
+    \image declarative-rect_tint.png
+
+    Tint is most useful when a subtle change is intended to be conveyed due to some event; you can then use tinting to more effectively tune the visible color.
+\section3 Qt.playSound(url soundLocation)
+This function plays the audio file located at \c soundLocation. Only .wav files are supported.
+
+\section3 Qt.openUrlExternally(url target)
+This function attempts to open the specified \c target url in an external application, based on the user's desktop preferences. It will return true if it succeeds, and false otherwise.
 \endlist
 
-It also contains enum values used by some items.
+\section1 Dynamic Object Creation
+The following functions on the global object allow you to dynamically create QML
+items from files or strings. 
 
-\section1 Asynchronous JavaScript and XML 
+You can also dynamically create objects in a declarative manner, using items
+such as ListView, Repeater and Loader. 
+
+\section2 createComponent(url file)
+    This function takes the URL of a QML file as its only argument. It returns
+    a component object which can be used to create and load that QML file.
+
+    Example QML script is below. Remember that QML files that might be loaded
+    over the network cannot be expected to be ready immediately.
+    \code
+        var component;
+        var sprite;
+        function finishCreation(){
+            if(component.isReady()){
+                sprite = component.createObject();
+                if(sprite == 0){
+                    // Error Handling
+                }else{
+                    sprite.parent = page;
+                    sprite.x = 200;
+                    //...
+                }
+            }else if(component.isError()){
+                // Error Handling
+            }
+        }
+
+        component = createComponent("Sprite.qml");
+        if(component.isReady()){
+            finishCreation();
+        }else{
+            component.statusChanged.connect(finishCreation);
+        }
+    \endcode
+
+    If you are certain the files will be local, you could simplify to
 
+    \code
+        component = createComponent("Sprite.qml");
+        sprite = component.createObject();
+        if(sprite == 0){
+            // Error Handling
+            print(component.errorsString());
+        }else{
+            sprite.parent = page;
+            sprite.x = 200;
+            //...
+        }
+    \endcode
+
+    If you want to just create an arbitrary string of QML, instead of
+    loading a QML file, consider the createQmlObject() function.
+
+\section2 createQmlObject(string qml, object parent, string filepath)
+    Creates a new object from the specified string of QML. It requires a
+    second argument, which is the id of an existing QML object to use as
+    the new object's parent. If a third argument is provided, this is used
+    for error reporting as the filepath that the QML came from.
+
+    Example (where targetItem is the id of an existing QML item):
+    \code
+    newObject = createQmlObject('import Qt 4.6; Rectangle {color: "red"; width: 20; height: 20}',
+        targetItem, "dynamicSnippet1");
+    \endcode
+
+    This function is intended for use inside QML only. It is intended to behave
+    similarly to eval, but for creating QML elements.
+
+    Returns the created object, or null if there is an error. In the case of an
+    error, details of the error are output using qWarning().
+
+    Note that this function returns immediately, and therefore may not work if
+    the QML loads new components. If you are trying to load a new component,
+    for example from a QML file, consider the createComponent() function
+    instead. 'New components' refers to external QML files that have not yet
+    been loaded, and so it is safe to use createQmlObject to load built-in
+    components.
+
+\section1 Asynchronous JavaScript and XML 
+QML script supports the XMLHttpRequest object, which can be used to asynchronously obtain data from over a network.
+\section2 XMLHttpRequest()
+In QML you can construct an XMLHttpRequest object just like in a web browser! TODO: Real documentation for this object.
 \section1 Offline Storage API
