Detailed Description

Member Function Documentation

QSGMetalTexture::QSGMetalTexture(QNativeInterface::QSGMetalTexture &&)

Default constructs an instance of QSGMetalTexture.

QSGMetalTexture::QSGMetalTexture(const QNativeInterface::QSGMetalTexture &)

Default constructs an instance of QSGMetalTexture.

QSGMetalTexture::QSGMetalTexture()

Default constructs an instance of QSGMetalTexture.

QNativeInterface::QSGMetalTexture &QSGMetalTexture::operator=(QNativeInterface::QSGMetalTexture &&)

Move-assignment operator.

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

Copy-assignment operator.

[virtual protected] QSGMetalTexture::~QSGMetalTexture()

Destroys the instance of QSGMetalTexture. The destructor is virtual.

[static, since 6.0] QSGTexture *QSGMetalTexture::fromNative(int texture, QQuickWindow *window, const QSize &size, QQuickWindow::CreateTextureOptions options = {})

Creates a new QSGTexture wrapping an existing Metal texture object for window.

The native object is wrapped, but not owned, by the resulting QSGTexture. The caller of the function is responsible for deleting the returned QSGTexture, but that will not destroy the underlying native object.

This function is currently suitable for 2D RGBA textures only.

Warning: This function will return null if the scene graph has not yet been initialized.

Use options to customize the texture attributes. Only the TextureHasAlphaChannel and TextureHasMipmaps are taken into account here.

size specifies the size in pixels.

Note: This function must be called on the scene graph rendering thread.

This function was introduced in Qt 6.0.

See also QQuickWindow::sceneGraphInitialized(), QSGTexture, Scene Graph - Metal Texture Import, and Scene Graph - Vulkan Texture Import.

int QSGMetalTexture::nativeTexture() const

Returns the Metal texture object.
