simvx.editor.panels.animation

Animation Timeline Panel – Keyframe animation editor with visual timeline.

Provides a Godot-style animation dope sheet for editing AnimationPlayer clips. Users can select tracks, insert/move/delete keyframes, scrub the playhead, and control playback – all with full undo/redo support.

Layout: +—————————————————-+ | [clip v] Player | << Play Pause Stop >> Loop | |———+——————————————–| | ruler | 0 0.25 0.5 0.75 1.0 1.25 … | |———+——————————————–| | pos.x x | <> <> <> | | pos.y x | <> <> | | rot x | <> <> <> <> | +—————————————————-+

The panel is the canonical public surface (AnimationPanel). Two private sibling helpers own cohesive responsibility groups and are injected with a back-reference to the panel:

• class:

  _TimelineRenderer – all dope-sheet drawing (header, ruler, track rows + keyframe diamonds, playhead, context menu).

• class:

  _TimelineInput – mouse/keyboard/scroll routing, header/track hit testing, and the context-menu interaction model.

Coordinate conversion, clip/selection model, transport, and the undoable keyframe/track operations remain on the panel itself (they mutate panel state and push to the editor undo stack). Helpers read and drive that state through the back-reference; the panel exposes thin delegators for every method the helpers moved so its external surface is unchanged.

[‘AnimationPanel’]

class simvx.editor.panels.animation.AnimationPanel(editor_state, **kwargs)

Bases: simvx.core.Control

Animation timeline panel for keyframe editing.

Displays an AnimationPlayer’s clips as a dope-sheet timeline. Supports playback controls, keyframe insertion/deletion/dragging, and interactive scrubbing – all routed through the editor undo stack.

Drawing and input routing are delegated to two private sibling helpers (:class:_TimelineRenderer, :class:_TimelineInput); the clip/selection model, coordinate maths, transport, and undoable operations live here.

Args: editor_state: The central State instance.
