Detailed Description

Provides a way of specifying the render surface.

The Qt3DRender::QRenderSurfaceSelector can be used to select the surface, where Qt3D renders the content. The surface can either be window surface or offscreen surface. The externalRenderTargetSize is used to specify the actual size of the surface when offscreen surface is used.

When DPI scaling is used by the system, the logical surface size, which is used by mouse events, and the actual 'physical' size of the surface can differ. The surfacePixelRatio is the factor to convert the logical size to the physical size.

Member Function Documentation

QRenderSurfaceSelector::QRenderSurfaceSelector(Qt3DCore::QNode *parent = nullptr)

Constructs QRenderSurfaceSelector with given parent.

[slot] void QRenderSurfaceSelector::setExternalRenderTargetSize(const QSize &size)

Sets render target size if different than underlying surface size. Tells picking the correct size.

Note: Setter function for property externalRenderTargetSize.

See also externalRenderTargetSize().

[slot] void QRenderSurfaceSelector::setSurface(QObject *surfaceObject)

Sets surfaceObject.

Note: Setter function for property surface.
