The QPlatformIntegration class is the entry for WindowSystem specific functionality.
\preliminary
QPlatformIntegration is the single entry point for windowsystem specific functionality when using the QPA platform. It has factory functions for creating platform specific pixmaps and windows. The class also controls the font subsystem.
QPlatformIntegration is a singleton class which gets instantiated in the QGuiApplication constructor. The QPlatformIntegration instance do not have ownership of objects it creates in functions where the name starts with create. However, functions which don't have a name starting with create acts as accessors to member variables.
It is not trivial to create or build a platform plugin outside of the Qt source tree. Therefore the recommended approach for making new platform plugin is to copy an existing plugin inside the QTSRCTREE/src/plugins/platform and develop the plugin inside the source tree.
The minimal platform integration is the smallest platform integration it is possible to make, which makes it an ideal starting point for new plugins. For a slightly more advanced plugin, consider reviewing the directfb plugin, or the testlite plugin.
Definition at line 73 of file qplatformintegration.h.
Capabilities are used to determine specific features of a platform integration.
\value ThreadedPixmaps The platform uses a pixmap implementation that is reentrant and can be used from multiple threads, like the raster paint engine and QImage based pixmaps.
\value OpenGL The platform supports OpenGL
\value ThreadedOpenGL The platform supports using OpenGL outside the GUI thread.
\value SharedGraphicsCache The platform supports a shared graphics cache
\value BufferQueueingOpenGL Deprecated. The OpenGL implementation on the platform will queue up buffers when swapBuffers() is called and block only when its buffer pipeline is full, rather than block immediately.
\value MultipleWindows The platform supports multiple QWindows, i.e. does some kind of compositing either client or server side. Some platforms might only support a single fullscreen window.
\value ApplicationState The platform handles the application state explicitly. This means that QEvent::ApplicationActivate and QEvent::ApplicationDeativate will not be posted automatically. Instead, the platform must handle application state explicitly by using QWindowSystemInterface::handleApplicationStateChanged(). If not set, application state will follow window activation, which is the normal behavior for desktop platforms.
\value ForeignWindows The platform allows creating QWindows which represent native windows created by other processes or by using native libraries.
\value NonFullScreenWindows The platform supports top-level windows which do not fill the screen. The default implementation returns true. Returning false for this will cause all windows, including dialogs and popups, to be resized to fill the screen.
\value WindowManagement The platform is based on a system that performs window management. This includes the typical desktop platforms. Can be set to false on platforms where no window management is available, meaning for example that windows are never repositioned by the window manager. The default implementation returns true.
\value AllGLFunctionsQueryable Deprecated. Used to indicate whether the QOpenGLContext backend provided by the platform is able to return function pointers from getProcAddress() even for standard OpenGL functions, for example OpenGL 1 functions like glClear() or glDrawArrays(). This is important because the OpenGL specifications do not require this ability from the getProcAddress implementations of the windowing system interfaces (EGL, WGL, GLX). The platform plugins may however choose to enhance the behavior in the backend implementation for QOpenGLContext::getProcAddress() and support returning a function pointer also for the standard, non-extension functions. This capability is a prerequisite for dynamic OpenGL loading. Starting with Qt 5.7, the platform plugin is required to have this capability.
\value ApplicationIcon The platform supports setting the application icon. (since 5.5)
\value TopStackedNativeChildWindows The platform supports native child windows via QWindowContainer without having to punch a transparent hole in the backingstore. (since 5.10)
\value OpenGLOnRasterSurface The platform supports making a QOpenGLContext current in combination with a QWindow of type RasterSurface.
\value PaintEvents The platform sends paint events instead of expose events when the window needs repainting. Expose events are only sent when a window is toggled from a non-exposed to exposed state or back.
\value RhiBasedRendering The platform supports one or more of the 3D rendering APIs that Qt Quick and other components can use via the Qt Rendering Hardware Interface. On platforms where it is clear upfront that the platform cannot, or does not want to, support rendering via 3D graphics APIs such as OpenGL, Vulkan, Direct 3D, or Metal, this capability can be reported as false. That in effect means that in modules where there is an alternative, such as Qt Quick with its software backend, an automatic fallback to that alternative may occur, if applicable. The default implementation of hasCapability() returns true.
\value ScreenWindowGrabbing The platform supports grabbing window on screen. On Wayland, this capability can be reported as false. The default implementation of hasCapability() returns true.
\value BackingStoreStaticContents The platform backingstore supports static contents. On resize of the backingstore the static contents region is provided, and the backing store is expected to propagate the static content to the resized backing store, without clients needing to repaint the static content region.

Factory function for the GUI event dispatcher.
The platform plugin should create and return a QAbstractEventDispatcher subclass when this function is called.
If the platform plugin for some reason creates the event dispatcher outside of this function (for example in the constructor), it needs to handle the case where this function is never called, ensuring that the event dispatcher is still deleted at some point (typically in the destructor).
Note that the platform plugin should never explicitly set the event dispatcher itself, using QCoreApplication::setEventDispatcher(), but let QCoreApplication decide when and which event dispatcher to create.

Factory function for QPlatformOpenGLContext.
The context parameter is a pointer to the context for which a platform-specific context backend needs to be created. Configuration settings like the format, share context and screen have to be taken from this QOpenGLContext and the resulting platform context is expected to be backed by a native context that fulfills these criteria.
If the context has native handles set, no new native context is expected to be created. Instead, the provided handles have to be used. In this case the ownership of the handle must not be taken and the platform implementation is not allowed to destroy the native context. Configuration parameters like the format are also to be ignored. Instead, the platform implementation is responsible for querying the configuriation from the provided native context.
Returns a pointer to a QPlatformOpenGLContext instance or \nullptr if the context could not be created.

Factory function for QPlatformWindow.
The window parameter is a pointer to the window which the QPlatformWindow is supposed to be created for.
All windows have to have a QPlatformWindow, and it will be created on-demand when the QWindow is made visible for the first time, or explicitly through calling QWindow::create().
In the constructor, of the QPlatformWindow, the window flags, state, title and geometry of the window should be applied to the underlying window. If the resulting flags or state differs, the resulting values should be set on the window using QWindow::setWindowFlags() or QWindow::setWindowState(), respectively.
