From 6c8378eaf1edbbefe6aaa3672b0127816a004fd7 Mon Sep 17 00:00:00 2001 From: Kent Hansen Date: Wed, 23 Nov 2011 15:14:07 +0100 Subject: Say hello to QtQuick module 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 " to "#include ".) 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.
