- drawPng uses top-left corner, drawText uses baseline
- Icon bottom (Y=42) now aligns with baseline at Y=42
- Icon top is at Y=26 (42-16), occupies Y=26 to Y=42
- Read icons/cut.png (not cut.png) to match embed directive
- Offset icon Y by iconSize so bottom aligns with text baseline
- drawText uses baseline positioning, drawPng uses top-left corner
- drawText positions glyphs by baseline, drawPng uses top-left corner
- Subtract iconSize from iconY so icon bottom aligns with text baseline
- Icon now renders within status bar instead of overlapping top
- Takes image.Image, position (x,y) in Dp, size (width,height) in Dp
- Tint color with alpha < 255 applies color overlay using clip.Rect
- Converts Dp to pixels using Renderer.toPx()
- Uses paint.NewImageOp for image rendering
- Takes image.Image, position (x,y) in Dp, size (width,height) in Dp
- Tint color with alpha < 255 applies color overlay using clip.Rect
- Converts Dp to pixels using Renderer.toPx()
- Uses paint.NewImageOp for image rendering
- StateReader interface in ui package (Scale(), ScreenWidth(), ScreenHeight())
- State implements StateReader
- Renderer reads scale/window size via interface, never imports editor
- State fields are private (screenWidth, screenHeight, scale) with accessor methods
- No SetScale/SetWindowSize calls from main.go — Renderer reads from State directly
- 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
