Research direction

Start by locating the window attribute setters and the platform integrations for WM_SETTEXT and KVO on NSWindow.title. Define the event coverage for title and the listed window attributes, including setter-driven changes and externally reported changes where supported; done means consumers can update custom title-bar controls from those events.

Written by the indexing model from the issue text.

Description

enhancement

There are no events when a window's attributes change, whether by the app or by the system: title, resizable / minimizable / maximizable / closable, always-on-top, and so on. A generic custom title bar can't update its buttons when some other part of the app calls setClosable(false).

Proposal: a WindowAttributesChangedEvent (or a few specific ones), emitted by the setters and, where the platform reports it, by external changes (for example WM_SETTEXT, KVO on NSWindow.title).
