Module: reefvision.desktop

Source: ./reefvision/desktop.reef

Overview

reefvision.desktop — Desktop + Application event loop (design §10.1–10.2)

object Desktop extends view.Group: windows are children via add. object Application is passive (not an Active Object). It owns terminal lifecycle, double-buffered cells, key/mouse decode, and the poll → dispatch → dirty-draw → flush loop.

Usage: mut app = new desktop.Application(theme.default_theme()) app.desktop().add(win) if app.open() while app.running() app.do_step() end while app.close() end if

F2 cycles built-in themes; F3 cycles canvas fill textures. Nested modals: app.message_box. Host I/O is reef_rv_* only (no curses). MenuBar is desktop chrome at row 0 (set_menubar), not a Group child.
