📝 Walkthrough

Walkthrough

The macOS root bridge now tracks press gestures, dispatches coordinate-bearing touch events, and sends a click only when a press ends without being marked as a drag. Gesture coordinates include the root or pane origin.

Changes

macOS Press Gesture Events

Layer / File(s)	Summary
Gesture tracking and event dispatch packages/geastack-apple/targets/macos/main/macos_renderer.mm	The bridge records the hit target and press coordinates, sends touch start, move, and end events, and includes pointer and touch coordinates. Movement greater than 16 units on either axis marks a drag. Single-root and pane synchronization update the bridge origin for tree-space coordinates.

Before / after behavior

• observed — Modified behavior in packages/geastack-apple/targets/macos/main/macos_renderer.mm: GeaRootClickBridge changes from a click handler to a press handler and adds origin, start/last-coordinate, and drag state for tracking gestures.
• observed — Modified behavior in packages/geastack-apple/targets/macos/main/macos_renderer.mm: fire: now converts the recognizer location to tree coordinates using the root origin and dispatches events with pointer, coordinate, and touch-point payloads. The old event helper supplied only type and target.
• observed — Modified behavior in packages/geastack-apple/targets/macos/main/macos_renderer.mm: On press begin, the bridge records the hit target and coordinates and sends TouchStart; on changed states, it sends TouchMove when coordinates differ and marks a drag when either axis moves more than 16 units. On termination it sends TouchEnd at the last coordinates, and sends Click only for an ended press that was not marked as dragged. The previous implementation sent no move events and clicked after every ended press.
• observed — Modified behavior in packages/geastack-apple/targets/macos/main/macos_renderer.mm: ensureRootClickBridge now accepts and stores a tree-space origin. It still creates and attaches a recognizer only when none exists, but refreshes the origin on every call; previously an existing bridge caused an immediate return without updating state.
