RegionPanelElement

Overview

Abstract base class for all widgets inside the Region Panel. Subscribes to the focused region and to a global updateRegionUI signal.

Serialized

• RegionVariable currentRegion
• RegionEvent currentRegionChanged
• VoidEvent updateRegionUI

Lifecycle

• Awake() — registers to both events.
• OnSelectedRegionChanged() — if the region exists, calls UpdateUI(); otherwise DisableUI().
• OnDestroy() — unregisters both handlers.

Derive from this and implement UpdateUI(); optionally override DisableUI().
