B5: Platform View Architecture

The source provides an architectural overview of Layer 5 in Chromium, which is responsible for interfacing the browser’s content output with the native operating system view layer. This layer is structured around two key cooperating classes: the RenderWidgetHostView (RWHV) and the WebContentsView (WCV). The RWHV is the platform-specific component that directly manages the visual output, tasked with displaying the rendered web content via the Viz compositor service and forwarding all native user input events to the appropriate browser host. Conversely, the WCV functions as the higher-level container for the entire browser tab's content, acting as the factory and parent for the RWHV and coordinating the web page area with peripheral browser elements like infobars. Through this tandem operation, Layer 5 successfully provides the essential platform glue that ensures accurate pixel representation and input channeling within Chromium's multi-process architecture.
