* Quick: Sanitize reading environment variables.Friedemann Kleint2015-10-261-1/+1
| | | | | | | | | | | | | | Where possible, use qEnvironmentVariableIsSet()/ qEnvironmentVariableIsEmpty() instead of checking on the return value of qgetenv(). Where the value is required, add a check using one of qEnvironmentVariableIsSet()/Empty(). Move QSGAtlasTexture::qsg_envInt() to qsgrenderer.cpp for reuse as qt_sg_envInt() and add qt_sg_envFloat().

* Remove the "groupNode"Gunnar Sletta2014-10-171-0/+15
| | | | | | | | | | | | | | | | | | 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.

* Say hello to QtQuick moduleKent Hansen2011-12-021-0/+1264
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.
