* Introduce cross platform high-dpi scalingMorten Johan Sørvig2015-07-301-1/+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.)

* FreeType: Support RGB rendering when not using FontConfigSérgio Martins2015-02-141-0/+9
| | | | | | | | | | | | | | | | | Windows+FreeType, Linux with -no-fontconfig and the forthcoming OSX FreeType engine can now use sub pixel rendering. The function to get the subpixel type is in QPlatformScreen because we're moving to per screen font settings in the future. This patch is safe, as no functionality is changed for existing users, if one wants sub pixel rendering they'll still have to pass -DFT_CONFIG_OPTION_SUBPIXEL_RENDERING to configure.

| | | | | | | | | | | | | | | | Use of this was removed from QtWayland quite a long time ago, which was the only public user of this API. Furthermore, it isn't easily possible to implement any use of this API without full control of the graphics stack (a very rare occurrence) and there is no public demonstration of this. There is ongoing research to provide a better replacement for this in the form of QPlatformHardwareCompositor.

* Basic high-dpi "retina" support for Qt 5.Morten Johan Sørvig2012-12-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Bring Qt 5 on par with Qt 4, prepare for more comprehensive support later on. Introduce device independent pixels (dips), device pixels, and devicePixelRatio. Add high-dpi support to QPainter, QGLWidget, the cocoa platform plugin, mac and fusion styles. Dips are similar to CSS pixels, Apple points and Android density-independent pixels. Device pixels are pixels in the backing store/physical pixels on screen. devicePixelRatio is the ratio between them, which is 1.0 on standard displays and 2.0 on "retina" displays.

* Expose QPA API under qpa/*Girish Ramakrishnan2012-05-071-0/+133
The main reasons for doing this are: 1. _qpa.h end up in the master QtGui include file. QtGui is meant for userland applications. qpa code is neither binary nor source compatible. Inadvertant use of QPA api makes the user code binary-incompatible. 2. syncqt creates forwarding headers for non-private header files. This gives people the impression that this is public API. As discussed on the mailing list, even though QPA api is internal and subject to change, it needs to treated differently from private headers since they will be used by in-qtbase and out-of-qtbase plugins. This commit does the following: 1. The _qpa in QPA header files is dropped. 2. syncqt now treats any file with qplatform prefix as a special file and moves it to qpa/ directory. The recommended way of using QPA API in plugins is: #include <qpa/qplatformfoo.h>. This allows the user include QPA API from multiple modules (for example, qplatformfoo might be in QtPrintSupport) 3. The user needs to explicitly add QT += <module>-private to get access to the qpa api. 4. Creates compat headers for the olden style qplatformfoo_qpa.h and QPlatformFoo includes. This commit does not change the cpp filenames. This requires a more careful merging of existing non qpa cpp files and existing cpp files on a case by case basis. This can be done at anytime. The following files are not renamed as part of this changed but will be fixed as part of a future change: src/gui/kernel/qgenericpluginfactory_qpa.h src/gui/kernel/qgenericplugin_qpa.h src/gui/kernel/qwindowsysteminterface_qpa.h files were renamed using for x in `find . -name "qplatform*_qpa.h"`; do git mv $x "${x/_qpa.h/.h}"; done for x in `find . -name "qplatform*_qpa_p.h"`; do git mv $x "${x/_qpa_p.h/_p.h}"; done includes were renamed using script for file in `find . -name "*.h" -or -name "*.cpp" -or -name "*.mm"`; do sed -i -e 's,.*#.*include.*<\(Qt.*/\)\?\(QPlatform.*\)>,#include <qpa/\L\2.h>,g' \ -e 's,.*#.*include.*"\(Qt.*/\)\?\(QPlatform.*\)",#include <qpa/\L\2.h>,g' \ -e 's,.*#.*include.* "\(qplatform.*\)_qpa.h",#include <qpa/\L\1.h>,g' \ -e 's,.*#.*include.*"\(qplatform.*\)_qpa_p.h",#include <qpa/\L\1_p.h>,g' \ -e 's,.*#.*include.*<\(Qt.*/\|Qt.*/private/\|private/\)\?\(qplatform.*\)_qpa\(.*\)>,#include <qpa/\2\3>,g' \ -e 's,.*#.*include.*"\(Qt.*/\|Qt.*/private/\|private/\)\?\(qplatform.*\)_qpa\(.*\)",#include <qpa/\2\3>,g' \ $file done Change-Id: I04a350314a45746e3911f54b3b21ad03315afb67 Reviewed-by: Morten Johan Sørvig <morten.sorvig@nokia.com> Reviewed-by: Samuel Rødal <samuel.rodal@nokia.com> Reviewed-by: Friedemann Kleint <Friedemann.Kleint@nokia.com> Reviewed-by: Sean Harmer <sean.harmer@kdab.com> Reviewed-by: Lars Knoll <lars.knoll@nokia.com> Reviewed-by: Gunnar Sletta <gunnar.sletta@nokia.com>
