fix(sidebar): move focus to editor when hiding a focused sidebar by BrettKinny · Pull Request #1490 · eugenioenko/ttt

BrettKinny · 2026-11-10T03:59:31Z

hideSidebar → if focus is in the sidebar, FocusEditor() first. Same as HideBottomPanel, but conditional: hiding the sidebar while e.g. the terminal has focus leaves focus alone.

In hideSidebar (not HideSidebar) so drag-to-close and empty-state hide are covered too.

Tests: internal/app/sidebar_hide_focus_test.go

sidebar focused → hide → editor focused (fails without fix)
terminal focused → hide → unchanged (fails with unconditional focus move)

Bug Fixes
- Hiding the sidebar now moves keyboard focus to the editor when focus is in the sidebar or the installed plugins tree. If focus is elsewhere, such as in the bottom panel, it remains there.

hideSidebar left focus on hidden panel → keys went to invisible explorer. Mirrors HideBottomPanel; only moves focus if sidebar had it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Walkthrough

When the sidebar is hidden, hideSidebar moves focus to the editor if focus is in the sidebar or plugins installed tree. Tests verify these focus changes and confirm that focus in the bottom panel remains unchanged.

Changes: Sidebar focus behavior

Layer / File(s)	Summary
Focus classification, sidebar hiding, and tests `internal/app/commands_view.go`, `internal/app/app.go`, `internal/app/sidebar_hide_focus_test.go`	`focusedRegion` classifies focus in the plugins installed tree as sidebar focus. When the sidebar has focus, `hideSidebar` moves focus to the editor. Tests cover sidebar focus, plugins tree focus, and unchanged bottom-panel focus.

The change improves sidebar hiding without introducing a known merge-blocking risk, though an existing overflow-menu focus case remains unfixed.

Explanation

Issue #1489 requires focus to move to the editor when the focused sidebar is hidden. App.hideSidebar checks focusedRegion() before hiding the sidebar and calls FocusEditor() when focus is in the sidebar. focusedRegion() also recognizes PluginsPanel.InstalledTree. Tests cover sidebar and plugin-tree focus moving to the editor, and focus outside the sidebar remaining unchanged.

Test focus after drag-to-close

Add a sidebar-focused test that closes the sidebar through resizeSidebar(0) and asserts editor focus. The toggle test cannot detect a regression that bypasses hideSidebar in the resize path; the existing drag tests do not assert focus.

Recognize inactive sidebar panels when hiding

If a user focuses a sidebar panel and selects a different panel from the overflow menu, the menu restores focus to the previous adapter. focusedRegion then classifies that adapter as "editor", so hiding the sidebar leaves focus there. Ordinary keyboard input can still go to the hidden panel instead of the editor. Include inactive sidebar panel targets in the hide focus check.
