__init__()¶

Constructs a default QQuickGraphicsDevice that does not reference any native objects.

__init__(other)

Parameters:: other – QQuickGraphicsDevice

static fromOpenGLContext(context)¶

Parameters:: context – QOpenGLContext
Return type:: QQuickGraphicsDevice

Returns a new QQuickGraphicsDevice referencing an existing OpenGL context.

This factory function is suitable for OpenGL.

Note

It is up the caller to ensure that context is going to be compatible and usable with the QQuickWindow . Platform-specific mismatches in the associated QSurfaceFormat, or threading issues due to attempting to use context on multiple threads are up to the caller to avoid.

static fromRhi(rhi)¶

Parameters:: rhi – QRhi
Return type:: QQuickGraphicsDevice

Returns a new QQuickGraphicsDevice referencing an existing rhi object.

Note

Similarly to fromOpenGLContext() , the caller must be careful to only share a QRhi (and so the underlying graphics context or device) between QQuickWindows that are known to be compatible, not breaking the underlying graphics API’s rules when it comes to threading, pixel formats, etc.

static fromRhiAdapter(adapter)¶

Parameters:: adapter – QRhiAdapter
Return type:: QQuickGraphicsDevice

Returns a new QQuickGraphicsDevice referencing an existing adapter QRhiAdapter object.

Not applicable to QRhi backends and graphics APIs where QRhiAdapter does not have a real implementation.

Equivalent to fromAdapter() for Direct 3D, and fromPhysicalDevice() for Vulkan.

Note

Ownership is not taken for adapter, and it must stay valid at minimum until the scene graph intializes, which most likely happens when the associated QQuickWindow becomes exposed.
