+ \ingroup qmlbasictypes
+
+ \brief A variant type is a generic property type.
+
+ A variant is a generic property type. A variant type property can hold any of the
+ \l {QML Basic Types}{basic type} values:
+
+ \qml
+ Item {
+ property variant aNumber : 100
+ property variant aString : "Hello world!"
+ property variant aList : [ 1, 2, "buckle my shoe" ]
+ }
+ \endqml
+
+ The \c variant type can also hold a \e copy of a JavaScript object. For example, the
+ \c animal property below defines a JavaScript object defined with JSON notation. The
+ object's properties and values can be examined using the standard JavaScript syntax,
+ as shown in the \c Component.onCompleted handler.
+
+ \qml
+ Item {
+ property variant animal : { 'type': 'bird', 'species': 'galah', 'age': 7 }
+
+ Component.onCompleted: {
+ for (var attribute in animal)
+ console.log(attribute, "=", animal[attribute])
+ }
+ }
+ \endqml
+
+ It must be noted that the \c animal property holds a \e copy of the defined object, and
+ not the object itself. (This is true even if the property refers to an object defined in
+ some JavaScript file; the property will hold a copy of the object, and not the actual
+ object.) The property essentially holds a copy of the contents within the object. This
+ has several implications:
+
+ \list
+ \o Changes to any of the property's values (for example, the \c animal.type value
+ above) only modify the \e copy of the object, not the object itself. You can, however,
+ modify a copy of the object and then reassign the property to the modified value.
+ \o Because the property only holds a copy of the object, \l{Property Binding}{bindings} to
+ any of the property's individual values are not updated until the whole property is
+ reassigned to a new value. For example:
+
+ \qml
+ Item {
+ property variant animal : { 'type': 'bird', 'species': 'galah', 'age': 7 }
+
+ Text { text: "Animal species: " + animal.species }
+
+ Component.onCompleted: {
+ animal.species = 'kookaburra' // this has no effect on the displayed text
+
+ var newObj = animal
+ newObj.species = 'kookaburra'
+ animal = newObj // this will update the displayed text
+ }
+ }
+ \endqml
+ \o Since the object values are copied, it does not hold any reference to the original
+ object, and extra data such as the object's JavaScript prototype chain is lost in the
+ process.
+ \endlist

-
- QML is a language for building the animation rich,
- highly fluid user interfaces that are becoming common in portable consumer
- electronics devices such as mobile phones, media players, set-top boxes and
- netbooks. It is also appropriate for highly custom desktop
- user interfaces, or special elements in more traditional desktop user interfaces.
-
- Building fluid applications is done declaratively, rather than procedurally.
- That is, you specify \e what the UI should look like and how it should behave
- rather than specifying step-by-step \e how to build it. Specifying a UI declaratively
- does not just include the layout of the interface items, but also the way each
- individual item looks and behaves and the overall flow of the application.
-
- The QML elements provide a sophisticated set of graphical and behavioral building
- blocks. These different elements are combined together in \l {QML Documents}{QML documents} to build components
- ranging in complexity from simple buttons and sliders, to complete
- internet-enabled applications like a \l {http://www.flickr.com}{Flickr} photo browser.
