This means it is no + longer subject to gui-thread only nor does it potentially impact + the 10.000 GDI object limit per process. By explicitly calling + .handle() a GDI object will be created and memory managed by + QRegion. The native handle is for reading out only.

The reason for + this is that Nokia focuses on OpenGL for desktop hardware accelerated + rendering. + + - The default engine used to draw onto OpenGL buffers has changed in + Qt 4.6. The QPaintEngine::OpenGL2 engine is now used as the default + engine. This *may* cause compatibility problems for applications + that use a mix of QPainter and native OpenGL calls to draw into a GL + buffer. Use the QGL::setPreferredPaintEngine() function to enforce + usage of the old GL paint engine. + + - When mixing OpenGL and QPainter calls you need to surround your + custom OpenGL calls with QPainter::beginNativePainting() and + QPainter::endNativePainting(). + This is to ensure that the paint engine flushes any pending drawing and sets + up the GL modelview/projection matrices properly before you can issue custom + OpenGL calls, and to let the paint engine synchronize to the painter state + before resuming regular QPainter based drawing. + + - Graphics View has undergone heavy optimization work, and as a result of + this work, the following behavior changes were introduced. + + a) QStyleOptionGraphicsItem::exposedRect now contains the item's bounding + rectangle, and QStyleOptionGraphicsItem::matrix is uninitialized by + default. You can enable an exact exposed rectangle and a correct matrix + by enabling the flag QGraphicsItem::ItemUsesExtendedStyleOptions. + + b) QStyleOptionGraphicsItem::levelOfDetails is obsoleted and its value is + always initialized to 1. Instead you can call + QStyleOptionGraphicsItem::levelOfDetailFromTransform(const QTransform &) + to determine the level of detail. + + c) QGraphicsView no longer calls QGraphicsView::drawItems(), and in turn + QGraphicsScene::drawItems(), by default. You can get the old behavior + back by enabling QGraphicsView::IndirectPainting. + + d) QGraphicsItem no longer calls itemChange() for position and + transformation changes. If you want to receive notifications for changes + to the item's position and transformation, you can set the flag + QGraphicsItem::ItemSendsGeometryChanges (which is enabled by default by + QGraphicsWidget and QGraphicsProxyWidget). + + - QDesktopWidget on X11 no longer emits the resized(int) signal when screens + are added or removed. This was not done on other platforms. Use the + screenCountChanged signal instead. + + - QUrl's parser is more strict when for hostnames in URLs. QUrl now + enforces STD 3 rules: + + * each individual hostname section (between dots) must be at most + 63 ASCII characters in length; + + * only letters, digits, and the hyphen character are allowed in the + ASCII range; letters outside the ASCII range follow the normal + IDN rules + + That means QUrl no longer accepts some URLs that were invalid + before, but weren't interpreted as such. + + - The Unix configure-time check for STL is stricter now in Qt + 4.6. This means some legacy STL implementations may fail to pass + the test and, therefore, Qt will automatically disable STL support. + + This is a binary-compatible change: existing code will continue to + work without being recompiled. However, it affects the source code, + since some STL-compatibility API will not be enabled. + + Platforms affected by this change: + * solaris-cc-* with the default (Cstd) C++ STL library + recommendation: use -library=stlport4 + See Sun Studio's documentation for the effects of this option + + - QVariant has now a new implicit constructor that takes a float. This + means that code that assigned a float to a variant would create a + variant with userType QMetaType::Float, instead of QVariant::Double. + + - QDataStream will now read and write all floating point numbers with the + same precision, regardless of whether it's streamed into or out from a + float or double. This is to maintain compatibility across platforms with + a different default precision for qreal. The default is 64-bit precision + for all floating point numbers, and this can be changed using the new + function setFloatingPointPrecision(). Set Qt_4_5 as the version of the + QDataStream to get the behavior of previous versions. + + - On Mac OS X, QDesktopServices::storageLocation(DataLocation) now includes + QCoreApplication::organizationName() and QCoreApplication::applicationName() + if those are set. This matches the behavior on the other platforms. + + - The Animation Framework + * currentTime() now returns the complete current time including previous + loops. + * currentLoopTime() returns the time inside the current loop. + * stateChanged signal sends the new state as first parameter and old state + as the second. + * QAnimationGroup::clearAnimations() has been renamed to clear(). + * QAnimationGroup::insertAnimationAt() has been renamed to + insertAnimation(). + * QAnimationGroup::takeAnimationAt() has been renamed to takeAnimation(). + * QSequentialAnimationGroup::insertPauseAt() has been renamed to + insertPause(). + * [QT-941] Avoids timer ticks when there are only pause animations running. + +- Refactoring in OpenGL examples to improve portability and utilize the + Animation framework for animation. The hellogl and overpainting examples + now compile on OpenGL/ES 1.1. Also common code is factored. + +- Changed QWebFrame::setHtml() and setContent() to not affect the back/forward + and the session history. + +- qmake no longer adds Qt internal dependencies to the linker when Qt + is built in shared mode (not static). This means that applications + that made use of platform-specific API may need to adjust the LIBS + variable in their .pro files to match: + + X11: LIBS += -lX11 + Mac: LIBS += -framework AppKit -framework Carbon + +- QtScript: Behavior changes due to using JavaScriptCore in the back-end: + * QDateTime is no longer used for date parsing and string conversion of + Date objects; instead the (more compliant) date processing from + JavaScriptCore is used. + * RegExp objects are no longer thin wrappers around QRegExp; they are now + "proper" JavaScript RegExp objects. +
