Events - menu | OPX//77

Client-local only: they reach handlers inside opx_infinity's client VM, not other resources.

Client, local. Raised after the owner's callback for every action on every menu.

AddEventHandler('opx:on:menu:action', function(payload) end)

Client, local. A menu opened, or the last one closed. Raised on change only. The HUD listens to it.

AddEventHandler('opx:on:menu:state', function(state) end)

Page channels

All on the interactive surface. Every payload carries the menu handle; a payload with a stale handle is dropped.

Channel	Direction	Payload	Meaning
`menu:key`	page → Lua	`{ handle, key, repeat }`	`key`: `up`, `down`, `left`, `right`, `enter` or `back`. Only sent when the page holds the keyboard (`focus = 'full'`).
`menu:choose`	page → Lua	`{ handle, index }`	A row was clicked: move there and activate it.
`menu:dismiss`	page → Lua	`{ handle }`	Escape on the page; closes with reason `dismissed`.
`focus:set`	page → Lua	`{ owner, focus }`	Shared by every view; the menu answers for owner `menu` only.
`menu:open`	Lua → page	first frame plus `anchor, width, maxHeight, height, focus, closable`	Re-sent until the page is ready.
`menu:frame`	Lua → page	`{ handle, title, trail, rows, first, total, hint }`	The visible window of rows.
`menu:close`	Lua → page	`{ handle }`	Take the menu down.
