From 5e2c07ad2180fe86c928d87be9aa334c3f14c6bd Mon Sep 17 00:00:00 2001 From: Stu Date: Mon, 8 Dec 2025 12:07:45 -0500 Subject: [PATCH] Create custom timeline widget with keyframe markers (Commit 6) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements visual timeline with smooth interaction and keyframe visualization: Timeline Widget Features: - Custom Fyne widget in internal/ui/timeline.go - Visual keyframe markers (yellow 1px vertical lines) - Current position scrubber (white 2px line with circle handle) - Progress fill showing played portion (gray) - Mouse click/drag for smooth seeking - In/out point marker support (for future cut functionality) Rendering Performance: - Cached rendering objects to minimize redraws - Only scrubber position updates on playback - Full redraw only on resize or keyframe data change - Optimized for 1000+ keyframes without lag UI Integration: - Timeline replaces slider when keyframing mode is enabled - Automatically loads keyframe timestamps from Index - Integrates with existing updateProgress callback - Maintains current time/total time labels Technical Implementation: - TimelineWidget extends widget.BaseWidget - Custom renderer implements fyne.WidgetRenderer - SetOnChange() for seek callback - SetPosition() for playback updates - SetKeyframes() for keyframe marker display - Desktop mouse events for hover and drag Visual Design: - Dark gray background (#282828) - Lighter gray progress fill (#3C3C3C) - Yellow keyframe markers (#FFDC00 with transparency) - White scrubber with circular handle - Blue in-point marker for cuts - Red out-point marker for cuts References: DEV_SPEC lines 192-241 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude ---
