* Android: Don't include Qt D-Bus by defaultEskil Abrahamsen Blomfeldt2015-02-251-1/+7
| | | | | | | | | | | | | | | | | | | | | Recently, a dependency on Qt D-Bus was added to Qt Platform Support if Qt was configured to support it. Since Qt defaults to checking for Qt D-Bus at run-time, the platform plugin and thus all applications would depend on libQt5DBus.so. Qt D-Bus really doesn't make much sense on Android, so we default to disabling it instead on this particular platform. People with use cases where this might be used can still configure Qt to include support by passing -dbus to configure. Note that this makes OS X and Linux builds consistent with Windows builds, where Qt D-Bus was already disabled because the dbus.h header was missing.

* Decide whether to synthesize mouse events on a per device basisAlexander Volkov2015-02-2520-66/+85
| | | | | | | | | | | | | | | | | | | | | Currently Qt uses the QPlatformIntegration::StyleHint SynthesizeMouseFromTouchEvents to check whether to synthesize mouse events from touch events. But not only platform plugins can produce touch events, they can be created by e.g. QTest::touchEvent() and in this case we almost definitely need synthesizing regardless of the platform. This commit introduces a QTouchDevice::MouseEmulation capability which replaces use of the QPlatformIntegration::SynthesizeMouseFromTouchEvents. So it's possible to pass QTouchDevice without this capability to QTest::touchEvent() and be sure that mouse events will be synthesized. Notice that touch pads always emulate mouse events. As a result we can activate some tests which were disabled for specific platform configurations by commits 6c1670d8c273819435867c42725c0db0eee597dc and e9760f1559361c39f269fb89f1ebd01f6ee8378d.

| * QtOpenGL: avoid crashing if creating a QGLContext sharing with the global ↵Giuseppe D'Angelo2015-02-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QOpenGLContext If one asks for the global OpenGL context via the right attribute, and then creates a QGLContext sharing with that context, Qt will create anoter, dummy QGLContext owned by the global context. At application shutdown, and specifically after ~QObject of QGuiApplication has run, the QObjectPrivate dpointer gets destroyed. That destroys the owning global QOpenGLContext, and therefore that dummy QGLContext as well. However, QGLContext dtor triggers a code path that accesses qApp as if it were still alive. That's not the case any more -- it has already been destroyed. So, introduce a check and avoid dereferencing NULL.
