Basic high-dpi "retina" support for Qt 5. 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. New API: QImage::devicePixelRatio() and setDevicePixelRatio() QPixmap::devicePixelRatio() and setDevicePixelRatio() QWindow::devicePixelRatio() QScreen::devicePixelRatio() QGuiApplicaiton::devicePixelRatio() Change-Id: If98c3ca9bfdf0e1bdbcf7574cd5b912c9ff63856 Reviewed-by: Morten Johan Sørvig <morten.sorvig@digia.com> Reviewed-by: Gunnar Sletta <gunnar.sletta@digia.com> 2012-11-20 10:34:52 +00:00			`TEMPLATE = app`

Extend high-DPI manual test Add several new tests to verify that Qt behaves properly when high-DPI scaling is enabled. Add a generic framework for manual tests for good measure. This could be refactored and used for other manual tests later. Includes tests written by Morten and Friedemann.

Add cmdline feature to qmake [ChangeLog][qmake] A new feature "cmdline" was added that implies "CONFIG += console" and "CONFIG -= app_bundle".

Update Dpi and scale factor computation Remove pixelScale() in favor of logicalBaseDpi(). Compute scale factor based on logical DPI and logical base DPI, or optionally based on the physical DPI. Add policies for running the scale factor and adjusting the logical DPI reported to the application. The policies are set via environment variables: QT_SCALE_FACTOR_ROUNDING_POLICY=Round\|Ceil\|Floor\|RoundPreferFloor\|PassThrough QT_DPI_ADJUSTMENT_POLICY=AdjustDpi\|DontAdjustDpi\|AdjustUpOnly QT_USE_PHYSICAL_DPI=0\|1 Done-with: Friedemann Kleint <Friedemann.Kleint@qt.io> Task-number: QTBUG-53022 Change-Id: I4846f223186df665eb0a9c827eaef0a96d1f458f Reviewed-by: Friedemann Kleint <Friedemann.Kleint@qt.io> 2016-04-25 09:31:34 +00:00			`DEFINES += HAVE_SCREEN_BASE_DPI`
