ZSurfaceViewEventHandler

interface ZSurfaceViewEventHandler(source)

Handler for surface view lifecycle and rendering events.

Implementations are typically created when a surface view is attached and receive callbacks for readiness, per-frame rendering, and resize. The platform ZSurfaceView should call dispose before clearing its reference to the handler so that the scene graph and renderer are properly torn down.

Functions

dispose

abstract fun dispose()

Disposes the handler and releases resources (scene graph, renderer). Should be called by the platform SurfaceView before clearing the handler reference.

onReady

abstract fun onReady()

Called when the surface is ready for rendering (e.g. context created, first frame).

onRender

abstract fun onRender()

Called each frame to perform rendering.

onResize

abstract fun onResize(width: Int, height: Int)

Called when the surface size changes.
