* macOS: Teach QWheelEvent to handle a new ScrollMomentum phaseTor Arne Vestbø2018-08-171-23/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We detect if there's an upcoming momentum phase using the same trick used by e.g. Mozilla in their event handling: https://tinyurl.com/yd8lcs4l, and as recommended by an Apple engineer: https://tinyurl.com/y8yytlgv The event is not guaranteed to be in the queue, but in practice it seems to be. If this assumption fails we can add a wait timeout to the event search instead of using [NSDate distantPast] as a timeout (which only looks at queued events). When the momentum phase is detected, QWheelEvent::phase will have the new ScrollMomentum value, and the phase transitions will be ScrollBegin -> ScrollUpdate -> ScrollMomentum -> ScrollEnd. We no longer send ScrollEnd to signify that the user's fingers have been lifted off the trackpad; rather, the first event with ScrollMomentum phase means that the fingers have been lifted and macOS is now sending simulated-momentum events. This means ScrollEnd is a reliable indicator that the entire scroll gesture (both the user interaction and the momentum) has ended. If the ScrollMomentum phase is skipped, it means the user's fingers came to rest before being lifted, so there is no momentum. In that case the transitions will be ScrollBegin -> ScrollUpdate -> ScrollEnd.

| * macOS: Force light theme on macOS 10.14+Gabriel de Dietrich2018-08-091-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until we can properly fix QPalette and QMacStyle, we should disable dark appearance in Qt applications. Disable by setting NSApp.appearance to Aqua, unless dark mode support has been requested via Info.plist or environment variable. Read the NSRequiresAquaSystemAppearance Info.plist key, don’t set NSApp.appearance if its value is false. Also check the QT_MAC_REQUIRES_AQUA_SYSTEM_APPEARANCE environment variable and apply similar logic. You then enable dark mode support by setting: QT_MAC_REQUIRES_AQUA_SYSTEM_APPEARANCE=0 which is slightly awkward, but matches Info.plist behavior.

* | macOS: Don't call [NSOpenGLContext update] for every frameTor Arne Vestbø2018-08-075-76/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling update has a cost, and should only be done when the drawable object changes size or location. Instead of calling update each time makeCurrent is called, we listen for the appropriate notifications, limiting the number of update calls significantly. The code has also been refactored to get rid of the m_activeWindow member, as the active window can be tracked through the context's drawable object property. There is also no need to clear the drawable when a window is hidden, so the hook into QCocoaWindow can be removed. The QPlatformNativeInterface hook is internal and can safely be removed.

| | * QCocoaMenuLoader - ensure that ensureAppMenuInMenu indeed, ensuresGabriel de Dietrich2018-08-011-18/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The logic seems to be incorrect (or the naming is misleading): it only adds 'appMenu' if it was found in the previous 'mainMenu', failing otherwise. Consider the following example: while (true){ QApplication app(a,b); MainWindow w; w.show(); app.exec(); } It's quite a contrived but apparently allowed API use (OP claims they have to switch languages in their app). The main window and the app are destroyed, so is the menu bar. Then a new main window is created, with a new menu bar. Now the current [NSApp mainMenu] (the one set after we deleted the previous) does not have 'appMenu' anymore (we removed it when initializing the first menu bar). So as a result we have app menu missing and add new menus/items to a wrong menus/at wrong index.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of trying to mask situations where [NSOpenGLContext setView:] will fail (such as calling it for a view that's not part of a window yet, or part of a window that hasn't been shown), we report the error up through the API, so that QOpenGLContext::makeCurrent() will return false. This is documented to occur e.g. when "the surface is not exposed, or the graphics hardware is not available due to e.g. the application being suspended." QGLWidget was taught how to deal with this situation in cc27a50e. Other Qt APIs seem to handle it fine, but if regressions occur they should be fixable though the same logic as in cc27a50e.

* | macOS: Remove declarative override of -[NSView wantsLayer]Alexandru Croitor2018-07-052-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The -[NSView setWantsLayer:] method may have side effects that extend beyond just setting an internal boolean property, so we need to ensure it gets called. This was observed on e.g. macOS 10.12.5, where the method ends up creating the internal backing layer. On later macOS versions the method just emits KVO notifications for wantsLayer, but these may in turn result in similar logic being triggered. The issue was masked somewhat by AppKit itself calling the method from e.g. -[NSWindow setContentView:], so we still got the backing layer created. The problem appeared when running binaries built against an older SDK (10.6 in this case), which triggered AppKit to not call -[NSView setWantsLayer:], due to __NSViewLayerBackWindowFrame() in that case returning false. This change removes the overridden -[NSView wantsLayer], and replaces it with an explicit call to -[NSView setWantsLayer] when creating a new QNSView, essentially revering c8c8cc790a315710b0dae2282dc32.
