What's New in Qt 5.0
Qt Core Changes
QStandardPaths
QStandardPaths is a more powerful version of QDesktopServices that was present in Qt 4. Modeled after KStandardDirs from KDE 4, it contains additional features such as searching for all occurrences of a given file in the storage locations.
Compile-time Checks for Signal-slot Connections
QObject now supports an additional syntax for connecting signals to slots, which forces the compiler to check whether the signal and the receiver exist and their arguments are compatible.
This syntax allows connecting a signal to any kind of C++ receiver, including C++11 lambdas, member functions, or static functions. The receivers no longer need to be declared as slots, but such declarations are still recommended for readability.
See Differences between String-Based and Functor-Based Connections for more details.
Perl-Compatible Regular Expressions
QRegularExpression is introduced to provide better support for regular expressions compatible with Perl. This class is more powerful and faster than QRegExp, and supports more features such as lazy and possessive quantifiers, lookbehinds, named capturing groups, and iteration of matches.
Qt GUI Changes
New Classes for Windowing and Rendering
A new set of enabler classes have been added, most importantly QWindow, QScreen, QSurfaceFormat, and QOpenGLContext. These are now used as backends for the Qt Widgets module and by Qt Quick 2.
OpenGL Classes
Most of the useful Qt OpenGL classes have been polished and moved into Qt GUI. A few important ones are, QOpenGLFramebufferObject, QOpenGLShaderProgram, QOpenGLFunctions, and so on. For the complete list, refer to Qt GUI C++ Classes.
This change introduces QOpenGLContext as a replacement for QGLContext. This replacement class is more generic and decoupled from QWindow, making it to support more use cases such as using the same context for multiple surfaces.
QOpenGLPaintDevice
Instead of having QWindow and QOpenGLFramebufferObject be subclasses of QPaintDevice, you can now use QOpenGLPaintDevice. This new alternative can be created on the stack, makes it easier and flexible to render into the currently bound context using QPainter.
Qt Network Changes
QDnsLookup
It is now possible to lookup DNS records using the new QDnsLookup API. This does not replace QHostInfo, which is still the API to be used for resolving a host name to an IP address. QDnsLookup is mainly used for other types of DNS record, such as SRV, TXT and MX.
Note: This new class replaces the Q3Dns API, which is removed in Qt 5.
Better Support for IPv6 and Dual-mode Networks
Most applications using host names and network layer transparent protocols, will now gain IPv6 support transparently. This means, QTcpServer and QUdpSocket bound to QHostAddress::Any can now receive both IPv4 and IPv6 connections, although, QHostAddress::AnyIPv4 and QHostAddress::AnyIPv6 can be used to bind to only one protocol.
Outgoing http connections using QNetworkAccessManager will now attempt both IPv4 and IPv6 connections in parallel, and use the one that succeeds first.
Binding TCP Sockets
QTcpSocket can be bound to an IP address before connecting, which is useful for limiting connection to a specific interface in a multi-homed environment.
SSL Certificates
SSL certificate extensions can now be accessed to enable further development of SSL support in Qt.
Developers can also verify an SSL certificate chain programatically now.
Workarounds for Buggy SSL Servers
The QSsl::SslOption enum now allows a QSslSocket-based code to access legacy systems by enabling bug workarounds.
Note: This change is also back-ported to Qt 4.8.
Support for Opaque Private Keys
This allows applications to read private keys from devices such as PKCS#11 dongles, as illustrated by the qsslkey example
Qt QML Changes
This is a new module in Qt 5 that provides the QML engine and the backend infrastructure.
QML Engine
- V8 JavaScript engine
- Various parser and compiler optimizations have been implemented along with the new bindings optimizer.
- Loading/compilation can now be performed in a separate thread. This can be enabled by loading a loader object asynchronously through its source property, or by passing the Component.Asynchronous parameter to Qt.createComponent().
- New QQmlEngine::trimComponentCache() function safely discards unused data in the engine’s component cache to free memory.
Type System
- New var property type can hold JavaScript references.
- QML properties of type var and variant can now hold pixmaps.
- Value type improvements:
- QColor is now a value type. The red, green, blue and alpha channels of a “color” property can now be accessed using “r”, “g”, “b” and “a” properties.
- Improved support for QVector4D, now constructible in QML using Qt.vector4d().
- 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 from JavaScript.
Other
- JavaScript (.js) files can now import QML modules and other JavaScript files using the “import” statement.
- QQmlExpression can now be constructed directly (and more efficiently) from a QQmlScriptString.
- The component returned by Qt.createComponent() is no longer the owned by the engine. Be sure to hold a reference,or provide a parent.
Qt Quick Changes
This is a new module in Qt 5 which provides the visual canvas and scenegraph backend as well as the QtQuick
QML module for QML-based application development.
The module replaces the QDeclarative* equivalents in QtQuick 1 with the following:
See Qt Quick C++ Classes for the complete list.
The QtQuick 2.0 QML module is a major update, and the following sections outline the features that come with it:
New Graphics Architecture
- Qt Quick 2.0 uses a dedicated OpenGL (ES) 2.0 based Qt Quick Scene Graph scene graph for all its rendering.
Visual and Graphic Types
- New Canvas type for drawing, provides a HTML5 canvas-like API along with the following additional features:
- Two render targets: Canvas.Image and Canvas.FramebufferObject.
- Background thread rendering.
- Tiled canvas rendering.
- Support for most of the HTML5 context2d APIs.
- Image type now has:
- New horizontal and vertical alignment properties, horizontalAlignment and verticalAlignment.
- Image.Pad enum value for
fillMode
property does not transform the image unlike the otherfillMode
enum values. - sourceSize.width and sourceSize.height now fits the image to size maintaining the aspect ratio.
Animations
- New SpriteSequence type renders animated sprites and can transition between animations.
- New Sprite type that represents each animation in a SpriteSequence.
- New AnimatedSprite type for drawing single sprite animations.
Changes to the Text types
- Text:
- AutoText format now switches to
StyledText
instead ofRichText
. - lineLaidOut signal is emitted for every line during the layout process to give the option of positioning and/or resizing text as they are laid out.
- doLayout() method can now trigger the text layout from JavaScript.
- ElideRight to support text that spans multiple lines.
- fontSizeMode property now supports wrapping the text to the item size.
- minimumPixelSize and minimumPointSize properties can be used to specify a lower bound when auto-fitting.
- AutoText format now switches to
- TextEdit.textFormat property now defaults to
PlainText
instead ofAutoText
. - TextInput now has
wrapMode
and verticalAlignment properties. TextInput.positionAt()
now takesy
value.
User Input
- New MultiPointTouchArea type can process multi-point touches and provide information about the touch points including position, pressure and velocity.
- MouseArea type now:
- Propagates wheel events.
- Propagates
clicked
,doubleClicked
andpressAndHold
events differently topressed
. These events are propagated to the handler of the topmost MouseArea in the stack-order. - Can ignore the propagated events using the
propagateComposedEvents
. Such ignored events are propagated to the next MouseArea handler in the stack-order.
Specialized Containers
- Flickable type now has:
- a new
rebound
property that enables you to specify the transition type for the bounce back animation. - New
topMargin
,bottomMargin
,leftMargin
, andrightMargin
properties allow extra margin space to be specified. This is useful to implement the pull-to-refresh functionality for a list. - New
xOrigin
andyOrigin
properties provide the top left position of the content item. - New
dragging
,draggingHorizontally
, anddraggingVertically
properties that provide information when the flickable area is dragged.
- a new
Positioners
The following features are related to Row, Column, Grid, and Flow types:
- The “add” and “move” transitions can now access the ViewTransition attached property, and also animate arbitrary item properties (instead of being restricted to animating an item’s position).
- New
Positioner.index
,Positioner.isFirstItem
andPositioner.isLastItem
attached properties for items within a positioner. - The Grid type has new
rowSpacing
andcolumnSpacing
properties. - All spacing properties on positioners now use real numbers instead of integers.
Models and Views
- ListView and GridView:
- Transitions can be specified to animate the adding, removing and moving of items in a view. For details, see ViewTransition, ListView.add, ListView.addDisplaced, GridView.add, and GridView.addDisplaced.
- New
verticalLayoutDirection
property enables items to be laid out from bottom-to-top using theBottomToTop
enum value. - The
cacheBuffer
property now has a non-zero default and delegates in thecacheBuffer
are created asynchronously. - New
headerItem
andfooterItem
properties provide access to the instantiated header and footer items. RightToLeft
layout now also reverses thepreferredHighlightBegin
andpreferredHighlightEnd
.
- ListView's new
section.labelPositioning
property can fix the current section label to the start of the view, and the next section label to the end of the view, so that labels do not scroll while section items are still in view. - PathView has two new properties,
curretnItem
andmaximumFlickVelocity
.
Particles System Support
The new QtQuick.Particles 2.0 module provides support for the composition of a variety of 2D particle systems. See Using the Qt Quick Particle System
for more details.
Utility Types
- New PathArc, PathCurve and PathSvg types:
PathArc
andPathCurve
support the construction of arcs and catmull-rom curves, respectively. PathSvg supports the construction of a path from an SVG string.
- Loader:
- New
asynchronous
property allows components to be instantiated with a lower chance of blocking. With theasynchronous
property set totrue
, the component is compiled in a background thread. - New
active
property delays instantiation of a Loader object’s item. - New
setSource(JSObject)
method to specify initial property values for the loaded item, similar to Component.createObject(). sourceChanged
signal is now only emitted when the source changes and thesourceComponentChanged
signal is now emitted when thesourceComponent
is changed. Ealier, these signals were emitted by the Loader only when one of the two properties had changed.- Loader type can now be used as a value source, and it can restore any previously set binding if its "when" clause becomes
false
.
- New
Qt Multimedia Changes
Qt Multimedia is an essential module replacing the QtMultimedia library and Qt MultimediaKit mobility API in Qt 4.8. It features full support for Audio and Video playback, and recording. Support for web cameras is integrated.
Qt Multimedia uses the system’s native multimedia engine as a backend, and does not come with its own audio or video codecs. Thus the supported list of codecs is equivalent to the ones supported by the underlying OS.
It uses DirectShow and WMF on Windows, AVFoundation on Mac and gstreamer on Linux.
