* Make Qt::Initialization a C++11 class enumThiago Macieira2015-08-101-0/+7
| | | | | | | | | | | | | | | | | | And declare Qt::Uninitialized to be the same value because we're not interested in the scoping rules of C++11 class enums. We're only interested in avoiding the cast from Qt::Uninitialized to an integer. That is to avoid the mistaken: QVector<Custom> vector(5, Qt::Uninitialized); which is actually implicitly: QVector<Custom> vector(5, Custom(Qt::Uninitialized)); and likely not what the developer wanted.

* | Introduce cross platform high-dpi scalingMorten Johan Sørvig2015-07-302-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a coordinate scaling layer to QtGui, which supports 'devicePixelRatio' type high-dpi on all platforms, in production and also for development and testing purposes. High-DPI scaling is opt-in, by setting environment variables: QT_SCALE_FACTOR - sets a global scale factor QT_AUTO_SCREEN_SCALE_FACTOR - sets per-screen scale factors, where the scale factors are provided by the platform plugin. This QtGui scaling can be used instead of or in addition to scaling done by the window system. This distinction is not visible to applications [when they use Qt API], which will see a change in the value returned by the devicePixelRatio() accessors as usual. Introduce a new (private to Qt) coordinate system: native pixels. The coordinate system stack now looks like: device-independent pixels (app, upper parts of Qt) native pixels (lower parts of Qt Gui, platform plugins) device pixels (backing stores and OpenGL) Add private QHighDpi namespace with scaling functions that convert between device-independent pixels and native pixels: T toNativePixels(T, QWindow *); T fromNativePixels(T, QWindow *); Add scaling calls the QWindow (and friends) cross-platform implementation, around the calls to QPlatformWindow functions. QPlatformWindow now uses native coordinates - platform code remains largely unchanged since native coordinates are window system coordinates. QWindow now uses (possibly) scaled coordinates. This means that platform plugins no longer can rely on QWindow::geometry() and related functions. QPlatformWindow::windowGeometry() and other convenience functions have been added for use when the platform plugin needs to convert scaled geometry to native geometry. Add Qt::AA_NoHighDpiScaling, which can be use to disable any scaling in QtGui, effectively ignoring the environment variables. (Note that this does not disable any scaling done by the window system.)

* | Refactor QVersionNumber so it stores values in-classThiago Macieira2015-07-292-21/+205
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The common case of QVersionNumber is that there are few segments and each segment is a small integers. So instead of allocating a QVector<int>, just store those numbers in the class itself if possible. Think of this as a "Small String Optimization" for QVersionNumber. QVector<int> costs 16 + 4*N bytes, plus malloc overhead. After this change, QVersionNumber(5,4,0) will have an overhead of zero. The memory layout is explained in the header. I've coded it so big endian also works, but I have not tested it at all. Aside from the special functions for QVersionNumber and operator>>, all the rest of the algorithm could have been left unchanged. I only updated segments(), normalized(), compare(), commonPrefix() and fromString() to take advantage of the smaller implementation in a more efficient way. Note: QVersionNumber's constructors often leave half of the object or more uninitialized. That's not a problem.

* | QStateMachine: add defaultTransition in QHistoryStateErik Verbruggen2015-07-236-21/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The history state had the limitation that it was hard (or impossible) to use when more than one default state had to be entered. For example, using it in a parallel state was impossible without ending up in an infinite loop. This patch changes the QHistoryState to only have an initial transition, and the state selection algorithm is changed accordingly. It also brings QStateMachine closer to the SCXML standard. The existing defaultState is implemented on top of the defaultTransition: when used, a new transition, with the default state as its target, is set as the defaultTransition.

| | | | | | | | | | | | | | | | | | | | | | | | A parallel state cannot have an initial state, as all children of the parallel state will be entered. Setting such an initial state on a QState marked as ParallelStates would already produce a warning and ignore the initial state. Now any initial state that has been set before changing the child-mode to ParallelStates will also produce a warning and remove the previously set initial state.
