◆ createEventDispatcher()

QAbstractEventDispatcher * QWasmIntegration::createEventDispatcher ( ) const

overridevirtual

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.

Since: 5.2

Implements QPlatformIntegration.

Definition at line 239 of file qwasmintegration.cpp.

◆ createPlatformBackingStore()

QPlatformBackingStore * QWasmIntegration::createPlatformBackingStore ( QWindow * window ) const

overridevirtual

Factory function for QPlatformBackingStore.

The QWindow parameter is a pointer to the top level widget(tlw) the window surface is created for. A QPlatformWindow is always created before the QPlatformBackingStore for tlw where the widget also requires a backing store.

See also: QBackingStore; createPlatformWindow()

Implements QPlatformIntegration.

Here is the call graph for this function:

◆ createPlatformOffscreenSurface()

QPlatformOffscreenSurface * QWasmIntegration::createPlatformOffscreenSurface ( QOffscreenSurface * surface ) const

overridevirtual

Factory function for QOffscreenSurface.

An offscreen surface will typically be implemented with a pixel buffer (pbuffer). If the platform doesn't support offscreen surfaces, an invisible window will be used by QOffscreenSurface instead.

Reimplemented from QPlatformIntegration.

Definition at line 226 of file qwasmintegration.cpp.

◆ createPlatformOpenGLContext()

QPlatformOpenGLContext * QWasmIntegration::createPlatformOpenGLContext ( QOpenGLContext * context ) const

overridevirtual

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.

Here is the call graph for this function:

◆ createPlatformWindow()

QPlatformWindow * QWasmIntegration::createPlatformWindow ( QWindow * window ) const

overridevirtual

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.
