Struct components::rendering::backend::WidgetRenderFactory

pub struct WidgetRenderFactory { /* private fields */ }

A rendering provider for a WidgetComponent. WidgetComponents will typically ask the rendering provider for a concrete control Renderer instance to associate with a given control. Framework specific rendering providers will extend this struct and return a Renderer instance for the requested type. i.e if (type == ::Canvas) return MyCanvasRenderer()
