Detailed Description#

See also

setGraphicsDevice() QQuickRenderTarget

__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.

isNull()#

Return type:: bool

Returns true if this is a default constructed graphics device that does not reference any native objects.
