* QHostInfo: Remove Darwin refusal to use getnameinfo(3)Thiago Macieira2017-08-241-2/+1
| | | | | | | | | | | | | | | | | This #if has been there since 0248ec4054b (Oct 2005), presumably due to bugs reported after the Qt 4.0 release (the first containing QHostInfo). Any macOS issues with getnameinfo() have long since been gone. I've confirmed that it works on 10.9, 10.10, 10.11 and 10.12, so I'm dropping the #ifndef. [ChangeLog][Deprecation Notice] Starting with Qt 5.10, IPv6 support will be mandatory for all platforms. Systems without proper IPv6 support, such as the getaddrinfo() function or the proper socket address structures, will not be able to build QtNetwork anymore.

* QWidget: Call appropriate QWindow method from setGeometry_sys()Gabriel de Dietrich2017-08-232-4/+11
| | | | | | | | | | | | | | | | | | | | | | | When calling resize() from showEvent(), we'd set the full geometry on the widget's QWindow. This resulted in the top-level window being moved to the top-left corner, even though no other call to move() or setGeometry() had happened before. The solution consists on calling the proper QWindow methods depending on whether setGeometry_sys() is called for a move, a resize or both. Furthermore, this needs QWindow::resize() to set its position policy to frame-exclusive. The documentation states that is already the case and we're setting the full geometry on the platform window, so we need to convey that bit of information. This also solves the age-old conundrum: "### why do we have isMove as a parameter?"

But it did not properly account for the full area occupied by the icon, because the horizontal padding is hardcoded to 4 in the mac style, whereas in the common style (where the icon is drawn) it uses the pixel metric for this. In addition, the change only allocated space on the left side, causing the label to no longer be centered.

* macOS: Fix matching of font weights for application fontsEskil Abrahamsen Blomfeldt2017-08-161-19/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5ad2e1cea1b2c08950c91174840f542806954d99 exposed a latent bug when matching font weights that do not exactly match any of the canonical weights in the system . It seems that when we registered the font with FontManager, it would modify the font weight to match a system weight, while we now get raw values from the font instead. So for Roboto Medium, for instance, we would now get 0.2 instead of 0.23, and since our conversion logic would convert everything between Light (-0.4) to Medium (0.23) to QFont::Normal, we would regard this as normal weight instead of medium. But on a linear scale, it makes more sense to match to the closest canonical weight instead of requiring exact matches. Note that the definition says that the middle between two weights should tend upwards, therefore we do the comparisons in decreasing order.

* Fix reset with qoffscreensurface destruction with multimonitor supportMäättä Antti2017-08-081-1/+1
| | | | | | | | | | | | | | | | | The qoffscreensurface::setScreen crashes in create if application is closing. This happens in multimonitor setup when one of the screens is already destroyed and qoffscreensurface handles the screenDestroyed signal. In this case the QGuiApplication::primaryScreen returns non-null surface and selects the codepath that recreates the surface. The create function calls the qGuiApp->thread function, which crashes since the application instance has already been set to nullptr. Prevent this in qoffscreensurface by checking the application instance in the setScreen function.
