- ConfigEvent: ONLY from app.ConfigEvent, sets width/height in State
- FrameEvent: gets scale from gtx.Metric.PxPerDp, sends ScaleEvent only if changed
- ScaleEvent: updates State.Scale
- Renderer reads windowW/windowH from State (SetWindowSize), not gtx.Constraints
- Renderer reads scale from State (SetScale), not gtx.Metric.PxPerDp
- main.go: ConfigEvent calls SetWindowSize, FrameEvent calls SetScale
- State.Scale stores the scale factor (default 1.0)
- ScaleEvent applies SetScale() which updates State.Scale
- Logic.Scale() accessor returns current scale
- Renderer.SetScale() updates renderer's scale from State
- main.go: uses logic.Scale() to get scale, calls renderer.SetScale()
- No more references to gtx.Metric.PxPerDp in render.go or main.go
- ConfigUpdate interface with apply(*State) method
- ConfigEvent and ScaleEvent both implement ConfigUpdate
- Logic.ConfigChan() accepts both types
- Type switch in Run() differentiates ConfigEvent vs ScaleEvent
- main.go sends both on same ConfigChan()
- Logic layer has separate ConfigChan and ScaleChan
- ConfigEvent: width/height in Dp, set on ConfigEvent
- ScaleEvent: scale factor, set on FrameEvent when scale changes
- Logic has ScreenSize() accessor for layout/rendering pipeline
- Logic has SetScale() to update scale and recompute layout
- main.go: ConfigEvent stores pixels, converts to DP using current scale
- main.go: FrameEvent gets actual scale, sends ScaleEvent if changed
The op.Record macro was leaving a clip on the stack that prevented
subsequent elements from drawing. Use clip.Rect{}.Push()/clip.Pop()
instead for immediate push/pop.
- Add ui.Dp and ui.Px as distinct named types
- Logic layer works exclusively in Dp (positions, sizes, regions)
- Renderer converts Dp→Px at Gio interop boundaries
- Capture gtx.Constraints once at start of Draw() for consistent positioning
- main.go converts app.ConfigEvent pixels to Dp before passing to logic layer
- Update documentation with new coordinate system architecture
- Create internal/editor/state.go with State struct and EditorLayout
- Create internal/editor/logic.go with Logic struct and Run method
- Logic owns all state, provides channels for config, frames, input, results
- Main goroutine uses editor.NewLogic() and logic.Run()
- Proper separation for testing later

Elements implemented:
- StatusBar (top bar with filename, action icons, conflict/search icons)
- BottomBar (bottom bar with cursor position, byte position, word wrap button)
- Button (interactive button element)
- AlphaIndex, SearchBar, Cursor, MergeHunk, Toast, Spacer (stubs)
Layout:
- EditorLayout function computes regions for StatusBar and BottomBar
- Filename truncation with ellipsis (mocked filename for testing)
- Mocked data: "very_long_filename...", "Ln 47, Col 12", "1024 / 50000"
Renderer:
- drawStatusBar: draws filename line + icon line
- drawBottomBar: draws cursor pos, byte pos, word wrap button
- drawButton: draws button text
- drawIconButton: draws icon buttons
Window resize:
- configChan setup in main.go
- ConfigEvent handling in event loop
- Layout recomputation on resize
Builds and runs successfully.
