* Change almost all other uses of qrand() to QRandomGeneratorThiago Macieira2017-11-084-5/+3
| | | | | | | | | | | | | | | | | | | The vast majority is actually switched to QRandomGenerator::bounded(), which gives a mostly uniform distribution over the [0, bound) range. There are very few floating point cases left, as many of those that did use floating point did not need to, after all. (I did leave some that were too ugly for me to understand) This commit also found a couple of calls to rand() instead of qrand(). This commit does not include changes to SSL code that continues to use qrand() (job for someone else): src/network/ssl/qsslkey_qt.cpp src/network/ssl/qsslsocket_mac.cpp tests/auto/network/ssl/qsslsocket/tst_qsslsocket.cpp Change-Id: Icd0e0d4b27cb4e5eb892fffd14b5285d43f4afbf Reviewed-by: Lars Knoll <lars.knoll@qt.io>

* make TabletMove hover events conditional on QWidget::tabletTrackingShawn Rutledge2017-02-231-0/+1
| | | | | | | | | | | | | | | | | | This adds the tabletTracking property in the same way that mouseTracking already existed: there is a WA_TabletTracking attribute, and a TabletTrackingChange event to notify when it changes. So for widget applications it's an opt-in feature. QtQuick applications don't yet make use of tablet events, but when they do in the future, we don't yet have a mechanism to turn the move events off; it remains to be seen whether that will be necessary. [ChangeLog][QtWidget] QWidget now has a tabletTracking property, analogous to mouseTracking, which will enable TabletMove events while the stylus is hovering, even if no button is pressed. This allows applications to show feedback based on the other tablet event properties such as rotation and tilt.

| * | add cross-platform tablet->mouse event synth; enable on AndroidShawn Rutledge2016-04-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's urgent to fix the issue that on Android, it became impossible to interact with any widget or MouseArea which handles only mouse events but not tablet events, using the stylus, because stylus events are sent only as QTabletEvents. Before 5.6 (change 01d78ba86a631386a4d47b7c12d2a359da28f517) they were sent as touch events, and mouse events were synthesized from those. Whereas on other platforms, every QTabletEvent is followed by a synthesized QMouseEvent. This fix proceeds in the direction that event synthesis should be done in cross-platform code so that platform plugins don't have to repeat it, following the same pattern as for touch->mouse synthesis. Just as in that case, the application can disable it, and the platform plugin can also report that it's unnecessary for Qt to do the synthesis because the platform already does. So QTBUG-51618 is fixed, but QTBUG-47007 requires us to remove the tablet->mouse synthesis from all platform plugins, because the plugin does not know whether the tablet event was accepted or not, so it does not have enough information to decide whether to synthesize a mouse event. Synthesis has been unconditional until now, which contradicts what the documentation says: the mouse event should be sent only if the tablet event is NOT accepted. We can now gradually make this promise come true. [ChangeLog][QtCore][Tablet support] A synthetic mouse event will no longer be sent after every QTabletEvent, only after those which are not accepted (as documented).
