Member Function Documentation

QEGLContext::QEGLContext()

Default constructs an instance of QEGLContext.

QEGLContext::QEGLContext(const QNativeInterface::QEGLContext &)

Default constructs an instance of QEGLContext.

QEGLContext::QEGLContext(QNativeInterface::QEGLContext &&)

Default constructs an instance of QEGLContext.

[virtual protected] QEGLContext::~QEGLContext()

Destroys the instance of QEGLContext. The destructor is virtual.

[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] EGLContext QEGLContext::nativeContext() const

Returns the underlying EGLContext.

QNativeInterface::QEGLContext &QEGLContext::operator=(const QNativeInterface::QEGLContext &)

Copy-assignment operator.

QNativeInterface::QEGLContext &QEGLContext::operator=(QNativeInterface::QEGLContext &&)

Move-assignment operator.
