| * Qt 5.9.4 Changes * | ||
| **************************************************************************** | ||
|
|
||
| QtCore | ||
| ------ | ||
|
|
||
| - [QTBUG-64529] Fixed a compilation issue with qfloat16 if AVX2 support is | ||
| enabled in the compiler. Since all processors that support AVX2 also | ||
| support F16C, for GCC and Clang it is recommended to either add -mf16c | ||
| to your build or to use the corresponding -march= switch. | ||
|
|
||
| - QCoreApplication: | ||
| * [QTBUG-58919] Fixed a crash if QCoreApplication is recreated on Windows | ||
| and the passed argv parameter is different. | ||
|
|
||
| - QFileInfo: | ||
| * [QTBUG-30148] Fixed isWritable() on Windows to return whether the given | ||
| file is writable only under current privilege levels. Previously, the | ||
| result would take into account privilege elevation. | ||
|
|
||
| - QObject: | ||
| * Fixed a crash that could happen if the context QObject pointer passed to | ||
| new-style connect() was null. | ||
|
|
||
| - QStandardPaths: | ||
| * On Windows, it is now possible to resolve configuration paths even | ||
| without QCoreApplication created. | ||
|
|
||
| - QString: | ||
| * QString::unicode(), constData() and `data() const` do not return a | ||
| NUL-terminated string. This was true before, but the documentation | ||
| claimed the opposite. | ||
|
|
||
| - QVector: | ||
| * Fixed a problem when calling removeAll() on an element from the | ||
| container, if the container had more than one copy of the that element. | ||
|
|
||
| - QXmlStreamWriter: | ||
| * [QTBUG-63538] Empty namespace URIs are now possible. | ||
|
|

| * [QTBUG-61463] Fixed a failed assertion that could happen when emitting a | ||
| signal from another thread. | ||
|
|
||
| QtNetwork | ||
| --------- | ||
|
|
||
| - QUdpSocket: | ||
| * [QTBUG-64718] Fixed a regression from Qt 5.9.3 caused by an apparent | ||
| Win32 API quirk we triggered when using readDatagram(), resulting in | ||
| an invalid QHostAddress sender address. receiveDatagram() was not | ||
| affected. | ||
|
|
||
| QtPrintSupport | ||
| -------------- | ||
|
|
||
| - QPrintDialog: | ||
| * [QTBUG-63933] Properly pre-select explicitly requested printer on | ||
| Unix. | ||
|
|
||
| QtWidgets | ||
| --------- | ||
|
|
||
| - QFileSystemModel: | ||

| allowing to track for example changes in file size. | ||
| * [QTBUG-64098] Fixed column alignment issues. | ||
| * [QTBUG-62841] Fixed assert when monitoring directories. | ||
|
|
||
| - QPixmapCache: | ||
| * [QTBUG-65475] Changing application palette runtime will now affect | ||
| (and invalidate) cached widget pixmaps used by the current style. | ||
|
|
||
| - QTreeView: | ||
| * [QTBUG-57538] Fixed issue with drag and drop sometimes being inaccurate. | ||
| * [QTBUG-63396] Fixed issue with child indicator not drawn correctly in RTL mode. | ||

| * [QTBUG-8376] Fixed row heights being wrong because of hidden columns. | ||
|
|
||
| - QTableView: | ||
| * [QTBUG-60219] Fixed grid lines being drawn outside header. | ||
|

||

|
|
||
| - iOS/tvOS: | ||
| * Qt will now take the safe area margins of the device into account when | ||
| computing layouts for QtWidgets. | ||
|
|
||
| - macOS: | ||
| * [QTBUG-57487][QTBUG-54160] If you have changed the button mapping of | ||
| your Wacom tablet in System Preferences, it will be respected by Qt | ||
| applications now. To revert to the old behavior, set the environment | ||
| variable QT_MAC_TABLET_IGNORE_BUTTON_MAPPING. | ||
|
|
||
| - macOS/iOS: | ||
| * [QTBUG-63476] Fixed an issue where text using one of the system theme | ||

|
||

| 1.7.4 to 1.7.5. This is because XIAllowTouchEvents is known to | ||
| deadlock with libXi 1.7.4 and earlier. When touch events are never | ||
| received, this is not an issue. Plain mouse / keyboard systems are not | ||
| affected. | ||
