* Move the model classes from QtQuick to QtQmlAlan Alpert2013-01-241-411/+0
| | | | | | | | | | | | | | | | | | | | | | | | This is needed for proper support of non-GUI instantiators in QtQml. Only private C++ classes are affected. Aside from name changes, model classes now operate on QObjects instead of QQuickItems, leading to minor changes in the implementation of QtQuick classes using them. The old QML type names will still be registered in the QtQuick import for the forseeable future, but pointing to the new classes. The new QML types will be added in a second commit. Classes Affected: QQuickVisualDataGroup -> QQmlDataGroup QQuickVisualDataModel -> QQmlDelegateModel QQuickVisualItemModel -> QQmlObjectModel QQuickVisualModel -> QQmlInstanceModel QQuickChangeSet -> QQmlChangeSet QQuickListAccessor -> QQmlListAccessor QQuickListCompositor -> QQmlListCompositor QQuickPackage -> QQuickPackage (just moved for now) Change-Id: Ia19e630e53bfa9e5d459e289596cd11df1ea3930 Reviewed-by: Andrew den Exter <andrew.den.exter@qinetic.com.au>

* Don't cache visual data model v8 handles.Andrew den Exter2012-07-101-2/+0
| | | | | | | | | | The external resource is reference counted and resused irregardless of whether the handles are cached, and the reduction in the number of handles allocated needs to be comes at the cost of keeping persistent handle which have a negative impact on garbage collection.

* Don't cache item indexes in VisualDataModel.Andrew den Exter2012-06-081-11/+12
| | | | | | | | | | | | | | Sacrifice constant time lookup of indexes for rarely used features for reduced memory usage. Applications which use neither Packages, nor the VisualDataGroup api don't ever need to query the index of an item so caching and maintaining those indexes in unnecessary. Where they are used this add a cost scanning for the index of an item in the cache, and in some instances a lookup cost in the compositor.

* Destroy incubated objects if they are not claimed when ready.Andrew den Exter2012-06-081-1/+2
| | | | | | | | | | If model data is removed while an object is incubating for it the view cannot cancel the incubation because the index is invalidated. So if the object has not been referenced after signalling it is ready assume it's been abandoned and destroy it.

* Don't parent (QObject) delegate items to views.Andrew den Exter2012-05-281-1/+2
| | | | | | | | | | | | This keeps object ownership within the context the items were created in and simplifies lifetime management as the VisualDataModel has sole license to delete objects and doesn't have to keep guards against a view and all it's children being deleted. Delegates are still reparented in the item heirarchy. Change-Id: Ife5afdfe294a5a8ca1ca3638a086f72452e4915c Reviewed-by: Martin Jones <martin.jones@nokia.com>
* Contruct per-delegate QQmlContextData directly.Andrew den Exter2012-05-241-13/+10
| | | | | | | | | | The QQmlContext object created per item is a weighty (QObject) wrapper around QQmlContextData that isn't utilized except as an intermeditrary for the QQmlComponent API. By duplicating a little code out of QQmlComponent we can avoid the need to ever contruct the wrapper.

* Minimize the number of objects created per item in VisualDataModel.Andrew den Exter2011-12-231-0/+403
Derive from QDeclarativeContext and reference count the context object instead of parenting it to the context. Combined with a weak persistent v8 handle the allows the context object to be returned by javascript accessors instead of creating a new instance for every use. In addition to the efficiency advantages of creating fewer objects, routing all data access through a single object means that object can also persist data instead of just acting as a proxy.
