* Freetype: Fix wrong line spacing for Courier NewEskil Abrahamsen Blomfeldt2016-09-301-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The regular variant of Monotype's "Courier New" font, the one which is included by default on Windows, has an EBLC table, which overrides the ascent and descent for certain sizes. The Freetype engine doesn't automatically respect this, so there is a hack in place to fetch the correct values for us. But there were two issues with that code, which lead to us getting the wrong line spacing for that particular font: The first was that we did not update the height metric for the font. This is used, together with the ascent and descent, to calculate the leading of the font. So when we set the height of text lines in a layout, we would get a leading based on the height for the scalable font and the ascent/descent from the EBLC table, and this would not match up. Also, as reported elsewhere on the Internet, the descent value in the EBLC table for Courier New is set to a positive value instead of a negative one. This must be a bug in the font, so we special case it and fix the value to avoid bogus line spacing later. [ChangeLog][Qt Gui][Text] Fixed line spacing with some scalable fonts containing bitmaps with the Freetype font engine.

Since the functions moved from network tests are now in a public header, had to massage them a bit to pass headersclean: - replace Q_FOREACH with C++11 range-for - avoid implicit conversion from QByteArray -> const char* (done by re-using toString(QByteArray) instead of calling strdup() manually) Also made the functions overloads instead of specializations. This allows to pass the enum by value instead of by const-&. Like the existing QHostAddress, the newly-added toString() overloads are marked as \internal. We can decide later whether to turn them into public API.

| | | | | | | | | | | | | | | If the mouse event is synthesized from a touchscreen, since we're using XI2 we've already delivered the actual touch event by the time an XI_Motion event occurs. It's bogus to treat the XI_Motion event as a mouse press merely because XIMaskIsSet pretends that the mouse button is pressed. If the QPA motion event says that the button is pressed, then QGuiApplicationPrivate::processMouseEvent() will synthesize an extra mouse button event for the press, and another for the release.

This could actually be a real problem, because it's trivial for a compiler to prove that these three lines unconditionally invoke UB, so it has all the right in the world to decide to drop the complete rest of the function, using this line of reasoning: 1. The only way for these three casts not to be UB is if event == nullptr. 2. If event == nullptr, then event->type() invokes UB, so event cannot be nullptr. 3. The only way both can be true is if this code path is never taken. I can thus assume that object == state && event->type() == QEvent::Timer is always true, drop the check and execute the if block unconditionally (I need to call QEvent::type(), to satisfy the as-if-rule, but I needn't check its return value). Fix by moving the casts where they belong: into each case of the switch, where the type of the event has been checked to match the target type of the cast.

The application author can set it to true if he wants to always use a Qt-rendered menubar instead; or, he can call QMenuBar::setNativeMenuBar(). Qt and its plugins should not override the author's wishes. Instead, if the platform plugin cannot create a native menubar for whatever reason, createPlatformMenuBar() will return null, and QMenuBar will fall back to using a Qt menubar instead. The application can check the result via QMenuBar::isNativeMenuBar(). QMdiArea when maximized inside a QMainWindow with an empty title does not replace the main window's title if we are using native menus. This behavior turned out to be the same on Unity as it is on macOS, so the autotest needed adjustment to expect that behavior whenever the menubar is native, not only on certain platforms. tst_QMenuBar::allowActiveAndDisabled() tests a standalone QMenuBar. In f92f78094 it was disabled on macOS, but on Ubuntu it passes as long as we force it to be a non-native menubar, so it should pass that way on macOS too. Removed unused variable RESET to fix warning. Task-number: QTBUG-54793 Change-Id: I716e40da709f96331cbbf25213bd7bc153e4dbe2 Reviewed-by: Morten Johan Sørvig <morten.sorvig@qt.io>

Fix the same code in QFileDialog, even though the autotest coverage is too limited for UBSan to point that one out explicitly.
