From 6d1ada9a90a162f2f1b7d652eafca72a881583d4 Mon Sep 17 00:00:00 2001 From: CleverThis Date: Wed, 13 May 2026 00:56:42 +0000 Subject: [PATCH 1/4] fix(tui): rename ActorSelectionOverlay._render to _refresh_display The `ActorSelectionOverlay` class inherits from `textual.widgets.Static`, which already defines a `_render()` method used for rendering widget content. Our private `_render()` was shadowing that method, causing incorrect repaint behavior and interfering with Textual's layout pass. This renames the internal method to `_refresh_display()` while keeping the public API unchanged.\n\nISSUES CLOSED: #11042 --- CONTRIBUTORS.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/CONTRIBUTORS.md b/CONTRIBUTORS.md index 27561d093..5c06947aa 100644 --- a/CONTRIBUTORS.md +++ b/CONTRIBUTORS.md @@ -24,7 +24,7 @@ # Details * HAL 9000 has contributed spec clarifications for layer boundary DI exception, ULID scope, ACMS pipeline contracts, and TUI component interfaces (PR #10451): documented architectural invariants including the DI container exception, clarified ULID identifier scope distinguishing domain entities from internal implementation details, added per-stage protocol contracts for all 10 ACMS pipeline stages with storage tier definitions, budget enforcement protocol, and context assembly output format, and defined public interfaces with verifiable checks for 8 TUI components. - +* HAL 9000 has contributed rename of `ActorSelectionOverlay._render` to `_refresh_display` to avoid shadowing Textual Widget internal method (PR #11042).
