\title What's New in Qt Quick
\page qtquick-whatsnew.html
\section1 Qt 5.0.0 includes QtQuick 2.0
QtQuick 2.0 is a major update.
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.
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.
QDeclarativeExpression can now be directly (and more efficiently) constructed from a
QDeclarativeScriptString.
Flickable: added dragging, draggingHorizontally and draggingVerically properties.
The Loader element 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.
\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 "qtquick1" module to the .pro file, e.g. QT += declarative qtquick1
QDeclarativeView and QDeclarativeItem headers are now in the QtQuick 1 module, i.e.
#include <QtQuick1/QDeclarativeView>
#include <QtQuick1/QDeclarativeItem>
"import QtQuick 1.0" loads the module dynamically. To deploy QtQuick 1 applications
the library (lib/libQtQuick1*) and plugin (imports/QtQuick/) must be installed.
\section1 Qt 4.7.4 includes QtQuick 1.1
QtQuick 1.1 is a minor feature update. \e {import QtQuick 1.1} to use the new
features.
\section2 PinchArea
PinchArea provides support for the common two finger pinch gesture.
\section2 LayoutMirroring attached property
\l {LayoutMirroring}{Layout mirroring} is useful when you need to support both
left-to-right and right-to-left layout versions of your application that target
different language areas.
\section2 Anchors
Added the following property:
\list
\o \l {Item::}{anchors.mirrored}
\endlist
\section2 Text
Added the following properties:
\list
\o \l {Text::}{lineHeight}
\o \l {Text::}{lineHeightMode}
\o \l {Text::}{lineCount}
\o \l {Text::}{maximumLineCount}
\o \l {Text::}{truncated}
\o \l {Text::}{effectiveHorizontalAlignment}
\endlist
horizontalAlignment now accepts Text.AlignJustify alignment mode.
\section2 TextEdit
Added the following properties, methods and signal handlers:
\list
\o \l {TextEdit::}{canPaste}
\o \l {TextEdit::}{lineCount}
\o \l {TextEdit::}{inputMethodComposing}
\o \l {TextEdit::}{mouseSelectionMode}
\o \l {TextEdit::}{effectiveHorizontalAlignment}
\o \l {TextEdit::}{deselect()}
\o \l {TextEdit::}{isRightToLeft()}
\o \l {TextEdit::}{moveCursorSelection()} to enable selection by word
\o \l {TextEdit::}{onLinkActivated}
\endlist
\section2 TextInput
Added the following properties and methods:
\list
\o \l {TextInput::}{canPaste}
\o \l {TextInput::}{inputMethodComposing}
\o \l {TextInput::}{mouseSelectionMode}
\o \l {TextInput::}{effectiveHorizontalAlignment}
\o \l {TextInput::}{deselect()}
\o \l {TextInput::}{isRightToLeft()}
\o \l {TextInput::}{moveCursorSelection()} to enable selection by word
\endlist
\section2 Image, BorderImage and AnimatedImage
Added the following properties:
\list
\o \l{Image::}{cache}
\o \l{Image::}{mirror}
\endlist
\section2 Item
Added the following properties:
\list
\o \l{Item::}{implicitWidth} and \l{Item::}{implicitHeight}
\endlist
\section2 Flickable
Added the following methods:
\list
\o \l{Flickable::}{resizeContent()}
\o \l{Flickable::}{returnToBounds()}
\endlist
\section2 MouseArea
Added the following property:
\list
\o \l{MouseArea::}{preventStealing}
\endlist
\section2 ListView and GridView
Added the following properties and methods:
\list
\o \l{ListView::}{layoutDirection}
\o \l{ListView::}{effectiveLayoutDirection}
\o \l{ListView::}{positionViewAtBeginning()}
\o \l{ListView::}{positionViewAtEnd()}
\endlist
\section2 Flow, Grid and Row
Added the following properties:
\list
\o \l{Flow::}{layoutDirection}
\o \l{Flow::}{effectiveLayoutDirection}
\endlist
\section2 Repeater
Added the following methods and signal handlers:
\list
\o \l{Repeater::}{onItemAdded}
\o \l{Repeater::}{onItemRemoved}
\o \l{Repeater::}{itemAt()}
\endlist
\section2 Component
\list
\o The \l{Component::}{createObject()} method now accepts a map of initial
property values for the created object.
\endlist
\section2 Qt
\list
\o Added the \l {QML:Qt::application}{Qt.application} object to hold generic
global application properties.
\endlist
\section2 Other changes
\list
\o Functions can be \l{Property Binding#Property Binding}{assigned to properties from JavaScript}
to create property bindings.
\o QtQuick now supports Right to Left layout in positioners, views, anchors and text elements.
\endlist
\section1 Qt 4.7.1
\section2 QtQuick namespace
In prior Qt releases, all the Qt Quick elements were available in the \e Qt
namespace. Starting with Qt 4.7.1, the elements are also available in the
\e QtQuick namespace, which improves naming consistency, and allows the
development of Qt Quick to occur at a faster rate than Qt's usual minor release
schedule.
The change for developers is very simple - where you previously wrote
\e {import Qt 4.7}, just replace it with \e {import QtQuick 1.0}, like this:
\code
import QtQuick 1.0
Text {
text: "Welcome to QtQuick 1.0!"
}
\endcode
\e {import Qt 4.7} continues to work so existing applications won't break even
if they aren't updated, but it is recommended that all import statements be
modified to the new form.
