* Remove out-of-line uses of qMalloc/qFree/qRealloc.Robin Burchell2012-01-121-1/+1
| | | | | | | | | Per http://codereview.qt-project.org/#change,11562, we are trying to remove these in favour of direct allocation, or (in the case of inline code) specialised out-of-line wrappers.

* VisualDataModel performance improvements.Andrew den Exter2011-12-231-22/+7
| | | | | | | | | | | | | | Avoid a linear scan of all cache items and associated accesses by getting the cache item from an objects vdm attached object instead. Make the model context property a property of the context object instead of a separate property on the context object. Parent the vdm attached object to the delegate object with QDeclarative_setParent_noEvent instead of passing it in the constructor.

* Insert items into VisualDataModel.Andrew den Exter2011-12-231-18/+225
| | | | | | | | | | | Add API for inserting data directly into a VisualDataModel which can be used among other things to create temporary items that are later resolved to an actual item in the source model.

* Minimize the number of objects created per item in VisualDataModel.Andrew den Exter2011-12-231-524/+248
| | | | | | | | | | | | | | 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.

* Don't emit model reset on completing a VisualDataModel.Andrew den Exter2011-12-151-1/+0
| | | | | | | | | The views try and retain their current state as much as possible on a reset which prevents the current item being set to a valid item as would happen if the VisualDataModel was completed before the view.

* Fix package items not being destroyed when a package is destroyed.Andrew den Exter2011-12-121-3/+3

* Say hello to QtQuick moduleKent Hansen2011-12-021-0/+2668
This change moves the QtQuick 2 types and C++ API (including SceneGraph) to a new module (AKA library), QtQuick. 99% of this change is moving files from src/declarative to src/quick, and from tests/auto/declarative to tests/auto/qtquick2. The loading of QtQuick 2 ("import QtQuick 2.0") is now delegated to a plugin, src/imports/qtquick2, just like it's done for QtQuick 1. All tools, examples, and tests that use QtQuick C++ API have gotten "QT += quick" or "QT += quick-private" added to their .pro file. A few additional internal QtDeclarative classes had to be exported (via Q_DECLARATIVE_PRIVATE_EXPORT) since they're needed by the QtQuick 2 implementation. The old header locations (e.g. QtDeclarative/qquickitem.h) will still be supported for some time, but will produce compile-time warnings. (To avoid the QtQuick implementation using the compatibility headers (since QtDeclarative's includepath comes first), a few include statements were modified, e.g. from "#include <qsgnode.h>" to "#include <QtQuick/qsgnode.h>".) There's a change in qtbase that automatically adds QtQuick to the module list if QtDeclarative is used. Together with the compatibility headers, this should help reduce the migration pain for existing projects. In theory, simply getting an existing QtDeclarative-based project to compile and link shouldn't require any changes for now -- but porting to the new scheme is of course recommended, and will eventually become mandatory.
