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 <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.

It can also add text, colors, - shadows, gradients, and patterns, and do low level pixel operations. The Canvas - output may be saved as an image file or serialized to a url. - - To define a drawing area in the Canvas item set the \c width and \c height properties. - For example, the following code creates a Canvas item which has a drawing area with a height of 100 - pixels and width of 200 pixels: - \qml - import QtQuick 2.0 - Canvas { - id:mycanvas - width:100 - height:200 - } - \endqml - - Currently the Canvas item only supports the two-dimensional rendering context. - - \section1 Threaded Rendering and Render Target - - The Canvas item supports two render targets: \c Canvas.Image and \c Canvas.FramebufferObject. - - The \c Canvas.Image render target is a \a QImage object. This render target supports background - thread rendering, allowing complex or long running painting to be executed without blocking the UI. - - The Canvas.FramebufferObject render target utilizes OpenGL hardware accelaration rather than rendering into - system memory, which in many cases results in faster rendering. - - The default render target is Canvas.Image and the default renderInThread property is - false. - - \section1 Tiled Canvas - The Canvas item supports tiled rendering by setting \l canvasSize, \l tileSize - and \l canvasWindow properties. - - Tiling allows efficient display of a very large virtual via a smaller canvas - window. The actual memory consumption is in relatation to the canvas window size. The painting - code can draw within the virtual canvas without handling coordinate system transformations. - - The tiles overlapping with the canvas window may be cached eliminating the need to redraw, - which can lead to significantly improved performance in some situations. - - \section1 Pixel Operations - All HTML5 2D context pixel operations are supported. In order to ensure improved - pixel reading/writing performance the \a Canvas.Image render target should be chosen. The - \a Canvas.FramebufferObject render target requires the pixel data to be exchanged between - the system memory and the graphic card, which is significantly more expensive. Rendering - may also be synchronized with the V-sync signal (to avoid {en.wikipedia.org/wiki/Screen_tearing}{screen tearing}) - which will futher impact pixel operations with \c Canvas.FrambufferObject render target. - - \section1 Tips for Porting Existing HTML5 Canvas applications - - Although the Canvas item is provides a HTML5 like API, HTML5 canvas applications - need to be modified to run in the Canvas item: - \list - \o Replace all DOM API calls with QML property bindings or Canvas item methods. - \o Replace all HTML event handlers with the \a MouseArea item. - \o Change setInterval/setTimeout function calls with the \a Timer item. - \o Place painting code into the \a QtQuick2::Canvas::onPaint handler and trigger - painting by calling the \c markDirty or \c requestPaint methods. - \o To draw images, load them by calling the Canvas's loadImage method and then request to paint - them in the onImageLoaded handler. - \endlist - - \sa QtQuick2::Context2D -*/ - -QQuickCanvasItem::QQuickCanvasItem(QQuickItem *parent) - : QQuickItem(*(new QQuickCanvasItemPrivate), parent) -{ - setFlag(ItemHasContents); -} - -QQuickCanvasItem::~QQuickCanvasItem() -{ - Q_D(QQuickCanvasItem); - delete d->context; -} - -/*! - \qmlproperty size QtQuick2::Canvas::canvasSize - Holds the logical canvas size that the context paints on. - - By default, the canvas size is the same size as the current canvas item size. - By setting the canvasSize, tileSize and canvasWindow, the Canvas - item can act as a large virtual canvas with many seperately rendered tile rectangles - Only those tiles within the current canvas window are painted by - the Canvas render engine. - - \sa QtQuick2::Canvas::tileSize QtQuick2::Canvas::canvasWindow -*/ -QSizeF QQuickCanvasItem::canvasSize() const -{ - Q_D(const QQuickCanvasItem); - return d->canvasSize; -} - -void QQuickCanvasItem::setCanvasSize(const QSizeF & size) -{ - Q_D(QQuickCanvasItem); - if (d->canvasSize != size) { - d->hasCanvasSize = true; - d->canvasSize = size; - emit canvasSizeChanged(); - polish(); - update(); - } -} - -/*! - \qmlproperty size QtQuick2::Canvas::tileSize - Holds the canvas rendering tile size. - - The Canvas item enters tiled mode by setting canvasSize, tileSize and - the canvasWindow.
