Member Function Documentation

[pure virtual, since 6.3] EGLConfig QEGLContext::config() const

Returns the EGLConfig associated with the underlying EGLContext.

This function was introduced in Qt 6.3.

[pure virtual, since 6.3] EGLDisplay QEGLContext::display() const

Returns the EGLDisplay associated with the underlying EGLContext.

This function was introduced in Qt 6.3.

[static] QOpenGLContext *QEGLContext::fromNative(EGLContext context, EGLDisplay display, QOpenGLContext *shareContext = nullptr)

Adopts an EGLContext context.

The same EGLDisplay passed to eglCreateContext must be passed as the display argument.

Ownership of the created QOpenGLContext shareContext is transferred to the caller.

[pure virtual, since 6.5] void QEGLContext::invalidateContext()

Marks the context as invalid

If this context is used by the Qt Quick scenegraph, this will trigger the SceneGraph to destroy this context and create a new one.

Similarly to QPlatformWindow::invalidateSurface(), this function can only be expected to have an effect on certain platforms, such as eglfs.

This function was introduced in Qt 6.5.

See also QOpenGLContext::isValid() and QPlatformWindow::invalidateSurface().

[pure virtual] EGLContext QEGLContext::nativeContext() const

Returns the underlying EGLContext.
