Detailed Description¶

The 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.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property externalRenderTargetSizeᅟ: QSize¶

Holds the size of the external render target.

Access functions:

externalRenderTargetSize()
setExternalRenderTargetSize()
Signal externalRenderTargetSizeChanged()

property surfaceᅟ: QObject¶

Holds the surface

Access functions:

surface()
setSurface()
Signal surfaceChanged()

property surfacePixelRatioᅟ: float¶

Holds the surfacePixelRatio of the surface.

Access functions:

surfacePixelRatio()
setSurfacePixelRatio()
Signal surfacePixelRatioChanged()

__init__([parent=None])¶
