Module hosted_window 

The window around an app its host shows in its own process.

An app in a process of its own reaches its window’s bar and its tab over its shell connection (crate::window_toolbar, crate::shell_tabs), which knows the asking app by its process. Apps a host mounts in its own process (the desktop’s Terminal tabs) share that process and its thread, so they cannot use those: the host lends each of them the window it shows it in, a HostedWindow (through HostContext::lend). On it the app declares its bar’s slots and asks to close its tab; the host draws the slots in the bar, hands back what the person did with them, and closes the tab the way the desktop closes any tab, the window with it when it was the window’s only tab.

The app’s side may be used from any thread: a shell that exits is seen by the thread reading its terminal, and the tab closes even while it is not the one the window shows.

An app need not know it shares a process: while a host’s TileHost runs the app it shows in a window (TileHost::set_hosted_window), crate::window_toolbar’s calls act on that window, so an app written for a process of its own declares its slots and hears its events the same way in either. What the host does with the windows is one crate::window_slots::WindowSlots in every desktop.

One window a host shows an app in, shared by the host and the app. Clones are the same window.
