Gfx::OutletPreviewLayer Class Reference
Inheritance diagram for Gfx::OutletPreviewLayer:
Process::EffectLayerView Process::LayerView Gfx::GeometryViewer::Layer Ui::TextureView::Layer Ui::VideoScope::Layer

Detailed Description

The view of a process that shows what its own texture outlet produces.

While the view is shown in a graphics view, a preview output follows the outlet. Being an output of the graph, the preview pulls the process, which then renders whether or not its outlet is cabled further.
