#+TITLE: Mouse Support (v0.10.0)
|
|
#+DATE: 2026-05-11

|
#+AUTHOR: Amr Gharbeia / Hermes

|
* Overview
|
|
|
|
Mouse event propagation through the component tree. The input system
|
|
already parses SGR mouse sequences into ~mouse-event~ structs. This
|
|
module adds:
|
|
|
|
1. A ~mouse-mixin~ class with event handler slots
|
|
2. Hit-testing: given (x,y), find the deepest component owning that cell
|
|
3. Event dispatch: route ~mouse-event~ → component handlers, bubble up
|
|
4. ScrollBox integration: wheel → scroll
|
|
5. Text selection: drag highlight + clipboard copy
|
|
|
|
** Contract
|
|
|
|
- ~mouse-mixin~ — mixin class with ~:on-mouse-down/up/move/scroll~ slots
|
|
- ~handle-mouse-event component event~ — dispatch to the right handler
|
|
- ~hit-test root x y~ → deepest component at (x,y)
|
|
- ~selection~ — highlighted text region (start-x, start-y, end-x, end-y)
|
|
- ~get-selection~ → selected text as string
|
|
- ~copy-to-clipboard text~ → pipe to xclip/wl-copy
|
|
|
|
