EditorCommand.h File Reference

EditorCommand is the discriminated union of every UI-thread→DOM mutation in the editor. New tools (path, node-edit, etc.) extend this variant as they land - one new case per logical operation, NOT one per ECS write. More...

Detailed Description

EditorCommand is the discriminated union of every UI-thread→DOM mutation in the editor. New tools (path, node-edit, etc.) extend this variant as they land - one new case per logical operation, NOT one per ECS write.

Canvas, tool, and application writes flow through EditorApp::applyMutation(), which pushes an EditorCommand onto the per-frame CommandQueue. The queue drains and coalesces at frame boundaries. Incremental source-pane edits use the separate guarded AsyncSVGDocument::applySourceEdit() seam; see Editor Architecture.
