* Fix QHighDpi::fromNativeLocalExposedRegion rounding errorsTor Arne Vestbø2017-07-191-4/+4
| | | | | | | | | | | | | | | | | | | | Calling bottom/right/bottomRight on a QRect is discouraged, as it does not give the true bottom-right corner of the rectangle, instead giving a point one unit to the left and top of the true bottom right. Dividing this point by a scale factor of e.g. 2, and then using qCeil on the bottom right x and y coordinates would result in a pointRegion that was 1x1 * scaleFactor larger than it should, manifesting as rendering issues at later stages. We can get away from the whole problem by initially converting the QRect to a QRectF, and basing the pointRegion's rect on the scaled size instead of bottom-right coordinates.

* Add qtguiglobal.h and qtguiglobal_p.hLars Knoll2016-07-031-1/+1
| | | | | | | | | | | | | | | | | | | | The new modular configuration system requires one global header per module, that is included by all other files in this module. A similar scheme and naming convention is already being used for many other modules (e.g. printsupport, qml, quick). That header will later on #include the configuration file for Qt Gui. For now it defines the Q_GUI_EXPORT macro for this library. In addition, add a private global header, qtguiglobal_p.h, that can later on include the private config header for Qt Gui for things we don't want to export to the world.

* Introduce cross platform high-dpi scalingMorten Johan Sørvig2015-07-301-0/+470
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.)
