* Make public headers compile with -Wzero-as-null-pointer-constantMarc Mutz2016-03-031-1/+1

* Remove the "groupNode"Gunnar Sletta2014-10-171-0/+1
| | | | | | | | | | | | | | | | | | We originally had the groupnode to simplify adding and removing clip / effect / opacity nodes to the item tree at a time when the renderer was a bit more trivial and only did a single pass over the tree during rendering. The runtime cost at the time was negligible. The QSGBatchRenderer has a bit more logic, so the extra node now costs a bit more. In addition to extra memory, we need to allocate shadow nodes for it and put those into the renderer's internal shadownode hash. This removal increases the performance of adding / removal of simple items by ~10% in addition to reducing the number of nodes in the scene graph by up to 1/3.

* Provide scenegraph backend API for marking scenegraph nodes dirty.Michael Brasser2014-02-151-0/+1
| | | | | | | | | | | Prior to Qt 5.2 tracking of dirty state was automatically handled by QSGNode. With Qt 5.2 this approach has changed. Moving forward render state is ideally tracked outside of QSGNode; however, we continue to provide a way to track it in the node itself, to support custom renderers and the default node updater.

* New scenegraph renderer and atlas textures.Gunnar Sletta2013-09-021-3/+14
| | | | | | | | | | | | | The renderer tries to batch primitives together where possible, isolate non-changing subparts of the scene from changing subparts and retain vertexdata on the GPU as much as possible. Atlas textures are crucial in enabling batching. The renderer and atlas texture are described in detail in the doc page "Qt Quick Scene Graph Renderer".

QSGNode and subclasses do not create a private instance by default. This is required by a follow-up commit where a new member needs to be added to QSGSimpleTextureNode. Protected ctors have been added to the superclasses of QSGSimpleTextureNode in the usual fashion.

* Say hello to QtQuick moduleKent Hansen2011-12-021-0/+346
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.
