| Qt 5.6.1 is a bug-fix release. It maintains both forward and backward |
| compatibility (source and binary) with Qt 5.6.0. |
| |
| For more details, refer to the online documentation included in this |
| distribution. The documentation is also available online: |
| |
| https://doc.qt.io/qt-5/ |
| |
| The Qt version 5.6 series is binary compatible with the 5.5.x series. |
| Applications compiled for 5.5 will continue to run with 5.6. |
| |

| **************************************************************************** |
| * Important Behavior Changes * |
| **************************************************************************** |
| |
| - Support for DirectFB is disabled by default, due to lack of |
| development in upstream. To enable the platform plugin, pass the |
| -directfb option to configure. |
| - [QTBUG-44964] The new X event compression feature that was added in 5.6.0 |
| no longer applies to motion events from drawing tablets. |
| |
| configure & build system |
| ------------------------ |
| |
| - The configure -D/-I/-L/-l/-R options do not affect the build of Qt's |
| host tools any more when cross-building. While this usually improves |
| the chances of a build succeeding, it may also require adjustments. |
| |
| qmake |
| ----- |
| |
| - [Unix] Paths passed to configure -R are not automatically used by 3rd |
| party projects any more. Use QMAKE_RPATHDIR if your project explicitly |
| depends on external libraries. Note that this is not needed for Qt or |
| its transitive dependencies. |
| - Expansions of ${QMAKE_FILE_IN_BASE} and ${QMAKE_FILE_OUT_BASE} in extra |
| compilers are now automatically quoted. |
| |
| **************************************************************************** |
| * Library * |
| **************************************************************************** |
| |
| QtCore |
| ------ |
| |
| - QObject: |
| * [QTBUG-52542] If the compiler supports variadic templates, functors |
| connected to signals will no longer be copied each time the signal is |
| emitted. |
| |
| - QRect: |
| * Fixed integer overflow in center(). This fixes the result for some |
| corner-cases such as a 1x1 rectangle at (INT_MIN, INT_MIN), for which the |
| previous implementation could return anything (due to invoking undefined |
| behavior), but commonly returned (0, 0). |
| |
| - QStringRef: |
| * Fixed relational operators against (const char*) to return the correct |
| result. |
| |
| QtGui |
| ----- |
| |
| - [QTBUG-50199] QWheelEvent::phase() now returns zero rather than |
| Qt::ScrollUpdate when the wheel event comes from an actual non-emulated |
| mouse wheel, and the QT_ENABLE_MOUSE_WHEEL_TRACKING environment variable |
| is set. |
| |
| - Image: |
| * [QTBUG-50745] Fixed possible crash in QImage::pixel() for mono or indexed |
| images. |
| |
| QtWidgets |
| --------- |
| |
| - Dialogs: |
| * [QTBUG-51148] Fixed font dialog support for fonts with a non-existent |
| family name and/or pixel size. |
| |
| - QHeaderView: |
| * [QTBUG-50171] Fixed a repainting issue when items had been reordered. |
| |
| - QListWidget: |
| * [QTBUG-15741] Fixed a bug that caused the default drop action to be |
| ignored when using icon mode. |
| |
| |
| **************************************************************************** |
| * Platform-specific Changes * |
| **************************************************************************** |
| |
| Android |
| ------- |
| |
| - The navigation bar is now hidden only on Android API level 19 and above. |
| |
| OS X |
| ---- |
| - [QTBUG-50262] QStandardPaths now returns the correct display name for the |
| download folder. |
| - [QTBUG-7000] QMacPrintEngine now really sets the printer resolution. |
| - [QTBUG-48138] QPinchGesture on OS X now behaves like on other platforms: |
| totalScaleFactor is the magnitude of the pinch and scaleFactor is the delta |
| for the current event. |
| |
| Windows |
| ------- |
| |
| - Text: |
| * [QTBUG-18711] Fixed disabling hints for application fonts. |
| For example, when automatic scaling by device pixel ratio is in effect. |
| * [QTBUG-47141] Made it possible to disable antialiasing for text when |
| drawing into images. |
| |
| X11/XCB |
| ------- |
| |
| - [QTBUG-49071] Fixed failure to deliver focusIn events on hide/show. |
| |

| ------------------------ |
| |
| - [QTBUG-11545][Windows] Added missing -pch/-no-pch options to configure.exe. |
| - [QTBUG-37952][Apple] configure -separate-debug-info is now supported. |
| - [QTBUG-47313][QTBUG-47639] Fixed builds with "debug" and/or "release" in |
| the build path's name. |
| - [QTBUG-51621][Unix] Fixed transitive dependencies on non-Qt libraries. |
| - [QTBUG-51644][QTBUG-53017] Fixed cross-builds which use a host compiler |
| which is significantly different from the target compiler. |
| - [QTBUG-52578][QNX] Unified some defaults between the Unix and Windows |
| configures. |
| - [Unix] configure -R now supports paths relative to -libdir. |

| - [QTBUG-51775][Unix@Windows] Fixed installation of target.targets when |
| cross-building. |
| - [QTBUG-51782] Fixed simultaneous use of the separate_debug_info and |
| no_plugin_name_prefix CONFIG flags. |
| - [QTBUG-52008] qmake-generated Visual Studio projects now automatically |
| invoke windeployqt by default. |
| - [QTBUG-52998] Restored use of -P option when invoking lex. |
| - The expansions ${QMAKE_FILE_IN_EXT}, ${QMAKE_FILE_IN_NAME}, and |
| ${QMAKE_FILE_OUT_PATH} are now understood in extra compilers. |
