sco_widgets_v1.remove_panel

Catalogue snapshot — development preview

SDK 2.3.0 · game pack 0.6.0 · source e616ed69d8f9f77b0f4827881c86d91e4a7d1689 Published release: sdk-v2.3.0 (immutable approved assets; this development preview is not an approved release). Source-backed inventory is not a runtime or in-game verification claim.

Removes an owned panel. Absent ID returns NOT_FOUND; success ends pending callbacks for that generation and permits immediate ctx destruction, including inside its callback. Failure preserves the panel.

Limitations / unestablished guarantees

• C# provides bounded copied UTF-8 trees and registry-rooted callbacks; Windows NativeAOT host loading remains unverified locally.
• Lua uses bounded declarative tables, registry-rooted callbacks and shared sandbox budgets; no native FFI or draw callbacks.
• Host adapter controls appearance/placement; native plugins are not sandboxed. Headless tests do not verify GPU rendering or gameplay.

Parameters and buffers

sco_result (*remove_panel)(sco_plugin* self, const char* id);
Removes an owned panel. Absent ID returns NOT_FOUND; success ends pending callbacks for that generation and permits immediate ctx destruction, including inside its callback. Failure preserves the panel.

Results and failures

OK; WRONG_THREAD off game thread; UNAVAILABLE stopped service/host; BAD_ARG invalid/released owner or malformed ID; NOT_FOUND absent owned panel. Failure leaves registration unchanged.

Absent capability

query_service NOT_FOUND absent service; UNAVAILABLE incompatible version. No game capability or renderer requirement.

Ownership

Host releases copied tree and borrowed callback registration, never frees plugin ctx; caller may free ctx after success.

Thread affinity

Game thread only; WRONG_THREAD elsewhere. Callbacks game thread under owner callout guard.

Callback context

Event, text and panel ID borrowed during callback only; callback ctx is plugin-owned.

Reentrancy

Callbacks may invoke commands or replace/remove own panel; generation change drops remaining stale events, new tree renders next pass. Registry lock not held during plugin code.

Cleanup and cancellation

Successful replacement/removal and ordinary owner release discard stale-generation events and end borrowed callbacks. Fault guard stops delivery; retained-provider faults skip ordinary resource release until restart. No separate cancel token.

Language mappings

Status labels are copied verbatim from the catalogue: direct is native access; typed-wrapper is wrapper-backed; restricted is a subset/adaptation; unsupported means no supported route is established. No status implies universal safety.
