  • Security Manager
  • Resource Manager
  • Window Manager
  • Compositor
  • Input Manager
  • Clipboard & Drag & Drop
  • Window Relationships
  • Menu Loop

  • Object Manager
  • Path Parser
  • Registry
  • File System Watcher

Methods

init()

Initializes the system, loads registry, starts desktop and taskbar.

Provides access to all subsystems:

  • getErrorManager()
  • getSecurityManager()
  • getResourceManager()
  • getWindowManager()
  • getCompositor()
  • getInputManager()
  • ... and all other subsystems

Subsystem Connections

The integration module connects subsystems:

  • Compositor ↔ Window Manager (window info)
  • Input Manager ↔ Window Manager (message sending)
  • Window Relationships ↔ Window Manager (window operations)
  • Focus Manager ↔ Window Manager (message sending)
  • Timer Manager ↔ Window Manager (WM_TIMER messages)

Usage Example

const FreeWorldSystem = require('./system/integration');

// Initialize system
const system = new FreeWorldSystem();
system.init();

// Access subsystems
const wm = system.getWindowManager();
const input = system.getInputManager();
const clipboard = system.getClipboard();

// Use system
const window = wm.createWindow('My App', 800, 600);
window.show();

// Shutdown
process.on('SIGINT', () => {
    system.shutdown();
    process.exit(0);
});
