doc: show pn.state.sync_busy in the busy how-to#8564
Merged
Conversation
The busy how-to only walked through the manual `pn.bind` pattern. Add a second section demonstrating `pn.state.sync_busy(indicator)`, the higher-level API that keeps a `BooleanIndicator` (e.g. `BooleanStatus`, `LoadingSpinner`) in step with `pn.state.busy` without writing the binding yourself. Closes holoviz#2334.

Thanks for the doc merge, @philippjfr. Showing sync_busy in context helps a lot. |

Closes #2334.
The busy how-to (
doc/how_to/state/busy.md) only showed the manualpn.bind(indicator, pn.state.param.busy)pattern.pn.state.sync_busyhas been onstate.pyfor years and is listed indoc/api/state.md, but a user reading the busy how-to or the indicator gallery has no reason to discover it.This adds a short second section to the how-to that demonstrates the direct API:
Verified
sync_busysignature inpanel/io/state.py:1021and confirmed the referenced indicator classes (BooleanStatus,LoadingSpinner) and theirBooleanIndicatorbase still exist inpanel/widgets/indicators.py.
