Surface() [1/3]

MayaFlux::Portal::Forma::Surface::Surface ( SurfaceConfig  config )

explicit

Construct a Surface from a SurfaceConfig.

Surface takes shared ownership of all three components. The caller is responsible for ensuring the Layer and Context were constructed against config.window. Wires the built-in close handling (Bridge::stop_sync plus a deferred window release) per config.should_detach_on_close(), then runs config.on_close if set. See SurfaceConfig's own doc for the composition rule between the two.

Parameters

config

Window, Layer, Context, and close-handling behavior.
