* Wait conditions example: fix an incorrect condition variable usageGiuseppe D'Angelo2022-12-292-15/+16
| | | | | | | | | | | | | | | | | | | | | 3a449bbb69c9a3c3a5bc6a052f2de98ab79be7e9 amended the code to remove acquiring a lock when waking up a condition variable. It is fine to not have a lock associated when waking a condition variable; what I misunderstood was the scope of the lock, which (and this underlines the importance of commenting _what exactly_ a lock protects, for each and ever lock) protected both the buffer as well as the counter of the buffer. This made my reasoning flawed: it is necessary to keep the lock while notifying, otherwise the counterpart could verify the condition isn't satisfied and wait (e.g. see numUsedBytes==0), missing the wake from the other thread (which could arrive between the check and the wait). Amends the previous commit.

* Port from qAsConst() to std::as_const()Marc Mutz2022-11-1831-67/+67
| | | | | | | | | | | | | | | | We've been requiring C++17 since Qt 6.0, and our qAsConst use finally starts to bother us (QTBUG-99313), so time to port away from it now. Since qAsConst has exactly the same semantics as std::as_const (down to rvalue treatment, constexpr'ness and noexcept'ness), there's really nothing more to it than a global search-and-replace. This is a 6.4 re-run of the script we ran in dev, in order to avoid conflicts between the branches when cherry-picking.

* Chip example: fix an accidental bool->int conversion when using PMF connectionsTang Haixiang2022-04-132-6/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The example was refactored to use the PMF connection syntax. However this introduced a problem: when connecting a QAbstractButton to a slot that has a default parameter, the semantics of the connection change between string-based connections and PMF. Specifically: when connecting the QAbstractButton::clicked(bool checked = false) signal to a slot like View::zoomIn(int level = 1) then a string-based connection like connect(button, SIGNAL(clicked()), this, SLOT(zoomIn())) would call zoomIn without carrying the signal's parameter over. In other words, zoomIn's parameter is defaulted. The same connection using PFM instead is connect(button, &QAbstractButton::clicked, this, &View::zoomIn) which would "connect" the arguments. This makes emissions that pass false as clicked's parameter result in a zoomIn by 0. Fix it by avoiding the default parameter of zoomIn -- just split the function in two (zoomIn and zoomInBy).

* Compose render-to-texture widgets through QRhiLaszlo Agocs2022-03-116-22/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QPlatformTextureList holds a QRhiTexture instead of GLuint. A QPlatformBackingStore now optionally can own a QRhi and a QRhiSwapChain for the associated window. Non-GL rendering must use this QRhi everywhere, whereas GL (QOpenGLWidget) can choose to still rely on resource sharing between contexts. A widget tells that it wants QRhi and the desired configuration in a new virtual function in QWidgetPrivate returning a QPlatformBackingStoreRhiConfig. This is evaluated (among a top-level's all children) upon create() before creating the repaint manager and the QWidgetWindow. In QOpenGLWidget what do request is obvious: it will request an OpenGL-based QRhi. QQuickWidget (or a potential future QRhiWidget) will be more interesting: it needs to honor the standard Qt Quick env.vars. and QQuickWindow APIs (or, in whatever way the user configured the QRhiWidget), and so will set up the config struct accordingly. In addition, the rhiconfig and surface type is (re)evaluated when (re)parenting a widget to a new tlw. If needed, this will now trigger a destroy - create on the tlw. This should be be safe to do in setParent. When multiple child widgets report an enabled rhiconfig, the first one (the first child encountered) wins. So e.g. attempting to have a QOpenGLWidget and a Vulkan-based QQuickWidget in the same top-level window will fail one of the widgets (it likely won't render). RasterGLSurface is no longer used by widgets. Rather, the appropriate surface type is chosen. The rhi support in the backingstore is usable without widgets as well. To make rhiFlush() functional, one needs to call setRhiConfig() after creating the QBackingStore. (like QWidget does to top-level windows) Most of the QT_NO_OPENGL ifdefs are eliminated all over the place. Everything with QRhi is unconditional code at compile time, except the actual initialization. Having to plumb the widget tlw's shareContext (or, now, the QRhi) through QWindowPrivate is no longer needed. The old approach does not scale: to implement composeAndFlush (now rhiFlush) we need more than just a QRhi object, and this way we no longer pollute everything starting from the widget level (QWidget's topextra -> QWidgetWindow -> QWindowPrivate) just to send data around. The BackingStoreOpenGLSupport interface and the QtGui - QtOpenGL split is all gone. Instead, there is a QBackingStoreDefaultCompositor in QtGui which is what the default implementations of composeAndFlush and toTexture call. (overriding composeAndFlush and co. f.ex. in eglfs should continue working mostly as-is, apart from adapting to the texture list changes and getting the native OpenGL texture id out of the QRhiTexture) As QQuickWidget is way too complicated to just port as-is, an rhi manual test (rhiwidget) is introduced as a first step, in ordewr to exercise a simple, custom render-to-texture widget that does something using a (not necessarily OpenGL-backed) QRhi and acts as fully functional QWidget (modeled after QOpenGLWidget). This can also form the foundation of a potential future QRhiWidget. It is also possible to force the QRhi-based flushing always, regardless of the presence of render-to-texture widgets. To exercise this, set the env.var. QT_WIDGETS_RHI=1. This picks a platform-specific default, and can be overridden with QT_WIDGETS_RHI_BACKEND. (in sync with Qt Quick) This can eventually be extended to query the platform plugin as well to check if the platform plugin prefers to always do flushes with a 3D API. QOpenGLWidget should work like before from the user's perspective, while internally it has to do some things differently to play nice and prevent regressions with the new rendering architecture. To exercise this better, the qopenglwidget example gets a new tab-based view (that could perhaps replace the example's main window later on?). The openglwidget manual test is made compatible with Qt 6, and gets a counterpart in form of the dockedopenglwidget manual test, which is a modified version of the cube example that features dock widgets. This is relevant in particular because render-to-texture widgets within a QDockWidget has its own specific quirks, with logic taking this into account, hence testing is essential. For existing applications there are two important consequences with this patch in place: - Once the rhi-based composition is enabled, it stays active for the lifetime of the top-level window. - Dynamically creating and parenting the first render-to-texture widget to an already created tlw will destroy and recreate the tlw (and the underlying window). The visible effects of this depend on the platform. (e.g. the window may disappear and reappear on some, whereas with other windowing systems it is not noticeable at all - this is not really different from similar situtions with reparenting or when moving windows between screens, so should be acceptable in practice) - On iOS raster windows are flushed with Metal (and rhi) from now on (previously this was through OpenGL by making flush() call composeAndFlush().
