Member Function Documentation
[constexpr noexcept default] QEGLContext::QEGLContext()
Default-constructs an instance of QEGLContext.
[delete] QEGLContext::QEGLContext(const QNativeInterface::QEGLContext &)
Copy-constructs an instance of QEGLContext. This function is deleted.
[delete] QEGLContext::QEGLContext(QNativeInterface::QEGLContext &&)
Move-constructs an instance of QEGLContext. This function is deleted.
[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.
[delete] QNativeInterface::QEGLContext &QEGLContext::operator=(QNativeInterface::QEGLContext &&)
Move-assigns other to this QEGLContext instance. This function is deleted.
[delete] QNativeInterface::QEGLContext &QEGLContext::operator=(const QNativeInterface::QEGLContext &)
Copy-assigns other to this QEGLContext instance. This function is deleted.
