The following -classes replace their equivalents in QtQuick 1: - -\list -\li QQuickView -\li QQuickCanvas -\li QQuickItem -\li QQuickPaintedItem -\endlist - -\section2 QML Engine/Language Improvements - -JS engine changed to V8. For most QML users this should not make a visible difference beyond performance improvements, however a lot of undefined behavior semantics may have changed as well. As always, it is recommended not to rely on undefined behavior. - -Parser and compiler optimizations. - -New binding optimizer. - -ValueType improvements: - - QColor is now a value type. The red, green, blue and alpha channels can be accessed via "r", "g", "b" and "a" properties - - Improved support for QVector4D, now constructible in QML via Qt.vector4d() - -Arbitrary functionality may be provided in a namespace through a Module API. See \l{qmlRegisterModuleApi()} for more information. - -JavaScript (.js) files may now import QML modules and other JavaScript files. See \l{Importing One JavaScript File From Another} for more information. - -A new property type "var" has been added which obsoletes the old "variant" property type. -Properties of the "var" type may hold JavaScript references. See \l{QML Basic Types} for more information. - -QML properties of type \c var and \c variant can now hold pixmaps. See \l{Scarce Resources in JavaScript} for more information - -QQmlExpression can now be directly (and more efficiently) constructed from a -QQmlScriptString. - -Support for certain sequence types (QList<int>, QList<qreal>, QList<bool>, QList<QUrl>, QList<QString> and QStringList) has been improved. -QObjects can define Q_PROPERTYs of these types which can be accessed transparently from JavaScript. See the section on -sequences in \l{Extending QML Functionalities using C++} for more information. - -\section2 Canvas Item - -The new \l Canvas item provides a HTML5 canvas like API, with some enhancements: -1) Supports 2 render targets: Canvas.Image and Canvas.FramebufferObject -2) Supports background thread rendering -3) Supports tiled canvas rendering - -The Canvas item supports most of the HTML5 context2d APIs, the API details please look at the canvas item documentation. - - -\section2 Particle System - -The \l{QtQuick.Particles 2}{QtQuick.Particles} module contains elements that can be composed to form 2D particle system. - - -\section2 Element API/Behavior Changes - -New \l SpriteSequence element renders animated sprites and can transition between animations. -It uses the \l Sprite element to represent each animation. For single sprites, there is also \l AnimatedSprite. - -MouseArea now propagates clicked, doubleClicked and pressAndHold differently to pressed. -These will now be propagated to the highest-stacking-order enabled MouseArea which has a handler for them. -You can still ignore these events in the handler to let them pass through. -This behavior is triggered with the new property propagateComposedEvents. - -The Binding element can now be used as a value source, and will also restore any previously -set binding when its \e when clause becomes false. - -Flickable: added dragging, draggingHorizontally and draggingVerically properties. -Added topMargin, bottomMargin, leftMargin, rightMargin, xOrigin, yOrigin properties. - -Image has two new properties: horizontalAlignment and verticalAlignment. It also has a new value for -fillMode (Image.Pad) that does not transform the image. -Setting Image sourceSize.width and sourceSize.height will now fit the image to the size, maintaining aspect. - -Grid now has rowSpacing and columnSpacing properties. Spacing properties on positioners are now real numbers instead -of integers. - -Positioner (Row, Column, Grid, Flow) improvements: -\list -\li Transitions used for \c add and \c move now have improved features: they can access a ViewTransition attached property (see the ViewTransition documentation for examples) and can now animate arbitrary item properties (instead of being restricted to animating an item's position). -\li Items in a positioner now have attached properties that can be used to determine a subitem's location: Positioner.index, Positioner.isFirstItem, Positioner.isLastItem. -\endlist - -Loader improvements: - - "active" property added to Loader, to allow delaying instantiation of a Loader element's item property - - "setSource(JSObject)" method added to Loader to allow initial property values to be specified (similar to Component.createObject()) - - now only emits the \c sourceChanged signal when the source is changed and the -\c sourceComponentChanged signal when the sourceComponent is changed. It used to emit both signals when one of the properties was changed. - -Text improvements: - - a \c onLineLaidOut handler is called for every line during the layout process. This gives the opportunity to position and resize a line as it is being laid out. - - a \c doLayout method was added to trigger the layout from Javascript. - - now automatically switch to StyledText instead of RichText if textFormat is set to AutoText. - -TextEdit: - - the default value of the textFormat property is now PlainText instead of AutoText. - -TextInput has new wrapMode and verticalAlignment properties, and the positionAt function now takes -a y parameter. - -PathView now has a \c currentItem property - -ListView and GridView: - - Can now apply specified transitions whenever items are added, removed or moved in a view. - See the documentation for ViewTransition and ListView.add, ListView.addDisplaced, - GridView.add, GridView.addDisplaced etc. for details. - - These now have headerItem and footerItem properties (the instantiated header and footer items). - - In RightToLeft layout the preferredHighlightBegin/End are now also reversed. - -ListView section.labelPositioning property added to allow keeping the current section label -at the start and/or next section label at the end of the view. - -A new property type ("var") has been introduced which obsoletes "variant" properties in QML. -Properties of this type are equivalent to regular JavaScript variables. See the documentation -on \l{QML Basic Types} for more information about "var" properties. - -New elements have been added for contructing paths: PathArc, PathCurve, PathSvg. - -\section2 QtQuick 1 is now a separate library and module - -Writing C++ applications using QtQuick 1 specific API, i.e. QDeclarativeView or QDeclarativeItem -requires adding the "quick1" module to the .pro file, e.g. QT += quick1 - -QDeclarativeView and QDeclarativeItem headers are now in the QtQuick 1 module, i.e. -#include <QtQuick1/QDeclarativeView> -#include <QtQuick1/QDeclarativeItem> - -\sa {What's New in Qt Quick 1}{What's New in Qt Quick 1} - -*/ |
